Great Lakes Are Improving from Legacy Chemicals but Fracking May Change That

Environmental Health News recently reported that,

“The Great Lakes hold 20 percent of the world’s fresh surface water. The good news is that legacy contaminants are decreasing more quickly than previously reported in three of the Great Lakes, but have stayed virtually the same in two other lakes, according to new research… Polychlorinated biphenyls (PCBs), the pesticide DDT and other banned compounds dropped about 50 percent in fish in Lakes Michigan, Ontario and Huron from 1999 through 2009, although there were no significant changes in Lakes Superior and Erie fish, according to the study to be published this month in the journal Science of the Total Environment.

“These are very positive results. The lakes are improving and slowly cleaning themselves up,” said Thomas Holsen, co-director of Clarkston University’s Center for the Environment and co-author of the study . “Even with the decreases, it will be 20 to 30 years until the decades-old contaminants in Great Lakes fish decline to the point that consumption advisories can be eliminated,” Holsen said.”

All good news, except as we clean up the old chemicals like Polychlorinated biphenyls (PCBs), the pesticide DDT and other banned compounds they are being replaced by newer ones, such as flame retardants that are building up in fish and wildlife and chemicals we are not yet even looking for from oil and gas development.

Today corporations are beginning hydro-fracturing (fracking) all around the Great Lakes to extract gas. It is against the law to frack under the lakes but there are no laws about fracking near streams, creeks, rivers that empty into the lakes. This is insane. Hundreds of very toxic chemicals are injected under pressure into the ground to fracture the shale formation. Not all of these chemicals are retrieved after the fracking is done. In fact the common gas well leaves behind about 30% of the chemicals, radioactive materials and brine. It’s unbelievable, hundreds of chemicals injected all around our fresh water lakes that both the U.S. and Canada have worked for decades to clean up.

This destructive activity is a prime example of governments’ tunnel vision. Oil and Gas development moves forward, cleanup of the lakes moves forward, air deposited of chemicals from many sources continues – – – it’s like shoveling the sidewalk in a blizzard, it won’t be cleaned until the snow stops falling. There is no sign of the chemical blizzards retreat.

I grew up near the lakes in Buffalo and understand their beauty and value. My sister and brother-in-law were active in advocating the cleanup of the lakes in the 1970’s. Our family vacationed on the lakes. It was exciting back then to hear that a serious effort from both sides of the boarder would advance to make the lakes swimmable, the fish safe enough to eat and so many other promises. Now over 35 years later reports are praising the cleanup of historical chemical deposits while at the same time new chemicals are allowed to enter the lakes without protest.

Fracking is not yet widespread around the great lakes. Yes there are some wells in PA, OH, MI but we can stop widespread fracking that would further contribute chemicals to our beautiful lakes by taking a stand and insisting that regulations are put in place and bans where necessary to protect this amazing gift of nature. It is up you and me to make it happen. For more information about the recent study of the Great Lakes, click here.

Using Blood Lead Levels to Set Cleanup Goals

Lead smelter in Kellogg, ID.The creativity of our government regulators never ceases to amaze me. I’ve seen a lot of incredibly stupid and callous decisions in my time, but this one is right up at the top. The US environmental Protection Agency (EPA) Region 10 and the Idaho Department of Environmental Quality somehow thought it was a good idea to use Blood Lead Levels in children to establish a remedial action objective (RAO) at the Bunker Hill Superfund site in Kellogg, ID. According to a recent peer reviewed paper published in the American Journal of Public Health, this decision is codified in EPA’s 1991 Record of Decision for the Bunker Hill site (1).

According to the authors, “the 1991 ROD for the Bunker Hill mine defined the EPA RAOs for child blood lead levels and stipulated the following criteria measures: (1) less than 5% of tested children should have blood lead levels greater than 10 micrograms per deciliter and (2) less than 1% of tested children should have blood lead levels greater than 15 micrograms per deciliter.” You got that. As long as no more than 5% of the children in Kellogg have blood lead levels greater than 10 micrograms per deciliter (ug/dl) and no more than 1% had levels great than 15 ug/dl, then the site cleanup efforts could be considered “successful” (1).

What was EPA thinking when they decided to use lead levels in children to define the effectiveness of a cleanup? And then, to accept that some children will have blood lead levels that exceed the recommended criteria is unconscionable. Even if this factor was not the sole criterion used to make decisions about the effectiveness of the cleanup, it is still unethical to use the children of Kellogg in this way.

The adverse health outcomes of exposure to lead are well understood. Earlier this year the Centers for Disease Control (CDC) revised its guidelines for lead lowering the blood lead level for protecting children’s health from 10 to 5 ug/dl. At the time CDC’s Advisory Committee for Childhood Lead Poisoning Prevention whose recommendations led to this change made it clear that no safe blood lead level in children has been identified.

Lead was mined at the Bunker Hill site for more than 100 years and at one time this was the home of the largest lead smelter in the United States. When the mine shut down in 1981, it left behind a toxic legacy of huge waste piles and residual contamination everywhere. Blood lead testing in children as earlier as 1976 found that 99% of Kellogg children living within 1 mile of the smelter who were tested had blood lead levels greater than 40 ug/dl (2). Today it is much less clear what the blood lead levels are because so few children are tested.

It is an injustice for EPA to treat the residents of Kellogg in this way. The residents In Kellogg have suffered disproportionately not only from lead exposure which continues to this day, but also from social disparities that include unemployment, poverty, and limited educational opportunity. Although there has been substantial cleanup at the site, it remains unclear whether there has been a corresponding improvement in community health and wellbeing. So much more needs to be done. This of course will never be achieved in communities like Kellogg, so long as decision makers think there’s nothing wrong with using the children as canaries in the mine fields.

It’s The Ground Game That Matters In Politics & Policy

The election is over and the analysis is being done. What worked, what didn’t and how can we learn from this experience? One strategy that everyone agrees worked was President Obama’s ground game; it made a difference.

On election night Donna Brazile a democratic advisor/strategist said that when the Obama campaign staff said they were going to re-energize their base and expand it she didn’t think expanding was necessary. She went on to say that she was wrong. Expanding the base was the right move.

Not surprisingly, that’s exactly what the environmental health and justice movement must do—energize and expand our base. The on-going top down strategy is not working we are not winning. For years the focus and majority of our resources have been placed in the Washington, D.C. environmental efforts rather than building the base . . . and it’s not working. The Climate Change legislation and energy issues, for example failed miserably.

Our movement needs a stronger ground game. We need to take the lessons learn from this past election and begin to build at the base in communities—not for a short term victory but to last over time with a continued effort toward growth. To accomplish this we need to shift resources to create a more balanced approach to change, investing in community groups as well as large D.C. environmental organizations.

Many believed that because of Citizen United that big money will dictate outcomes of issues and/or elections and community organizing is no longer critical to winning. They believe purchasing a full page ads, getting our messages right, investing in lawyers, scientists and so on is the way to win. Again Obama’s campaign demonstrated that all of that ads, message and so on is important but only when directly coupled to an organized, connected and strategic base of community organizations.

The Obama campaign is not the only example of where the ground game mattered. If you look at New York State and the issue around hydro fracturing you’ll see that the governor wanted to move fracking forward. However, due to a massive organizing at the base across the state fracking has been stopped at least temporarily. There were scientists, lawyers and lobbyists involved in that struggle as well, but it was the people at the streets that tipped the scale and forced the governor to rethink his position.

Today we have confirmation of what needs to happen for our issues to move forward—a strong ground game and shifting ample resources to sustain that effort. Large donors and foundations need to rethink their giving decisions and invest more dollars in the base. We need that base to work smarter not harder to energize and expand the reach, goals and breathe of people.

Hurricane Sandy was our most recent wake up call to the enormity of our problems. We can’t afford to move slowly. Today is the day, now is the time for everyone to think about how you can help to build, strengthen, and connect the grassroots efforts for change.

Health Effects Associated with Natural Gas Extraction using Hydraulic Fracturing or Fracking

Perhaps the most intense public health issue to hit the east coast in the past five years is the extraction of natural gas using hydraulic fracturing, more commonly referred to as fracking. This process involves mixing more than a million gallons of water, sand and proprietary toxic chemicals and injecting this mixture at very high pressure into horizontally drilled wells as deep as 10,000 feet below the surface. This pressurized mixture causes the rock layer to crack creating fissures or passage ways in the rock. These fissures are held open by the sand particles so that natural gas from the shale can flow back up the well. This technique has proven so effective at reaching previously hard-to-reach oil and gas reserves that it has spurred a boom in natural gas production around the country.

This boom in natural gas production has also spurred a boom in community activism in areas targeted for drilling such as the Marcellus Shale, a layer of sedimentary rock that spans nine states including NY, PA, and OH.  Drilling in these areas has brought controversy and anger to the impacted communities.

People who live next to these drilling sites are reporting a wide range of adverse health effects including respiratory difficulties, skin rashes, digestive disorders, and neurological problems. There are complaints of foul odors, water pollution, incessant noise and 24 hours per day production.

This past week-end I heard first hand about these problems, as CHEJ conducted two training workshops in western PA. The first workshop was in Dubois, in north western PA in Clearfield County. The host group was Pennsylvania Alliance for Clean Water & Air (PACWA). They shared a “List of the Harmed,” a report describing 565 people with adverse health and environmental problems related to fracking sites. This is an incredible collection of first hand accounts of the impacts of fracking that covers the entire country.There was more of the same the next day in Butler.

In preparing for a presentation on the health impacts of fracking, I searched the published literature for papers that addressed this issue. I found none, though my search led me to a colleague who is presenting a paper on this very topic at the annual meeting of the American Public Health Association this week in San Francisco. She alerted me to a paper in the published literature by Michelle Bamberger and Robert Oswald, researchers at Cornell University in NY. This paper, “Impacts of Gas Drilling on Human and Animal Health,” published this year in the journal New Solutions, was  the only paper that she had found.

This paper includes 24 case studies that describe animal health effects and some human health effects in 6 states. Owners of livestock were interviewed who had suspected water and air exposures associated with living near natural gas extraction wells. The livestock had suffered a variety of adverse health effects including reproductive, skin, digestive, urological, respiratory and neurological problems, and in some cases sudden death. The owners in many cases experienced health effects as well. These effects included respiratory and neurological problems, skin rashes and digestive problems. These findings are similar to what PACWA reported in their List of the Harmed.

Another excellent summary on the human health risks posed by fracking was prepared by scientists for the Grassroots Environmental Education organization. This paper, “Human Health Risks and Exposure Pathways of Proposed Horizontal Hydrofracking in New York,” was presented at a meeting with state officials in Albany, NY earlier this month.

At this time, there are very little scientific data (one paper) documenting adverse human health effects resulting from the extraction of natural gas using hydrologic fracturing. Meanwhile, grassroots activists are organizing and collecting their own data documenting adverse health effects in people living near natural gas drilling sites. It’s clear that a number of hazardous and toxic chemicals are used in and produced by the fracking process. It’s also clear that a number of very realistic and in some cases documented routes of human exposure exist. But without additional information, including on the proprietary chemicals mixed in with the drilling fluids, the public health risks of natural gas extraction from hydrologic fracturing will be difficult to quantify.

Halloween's Toxic Troubles

This Halloween, Hurricane Sandy left behind toxic troubles from sewage and flooded hazardous waste sites in the New York City area. Huffington Post reported that, “Left in the wake of Hurricane Sandy, the toxic stew may threaten the health of residents already dealing with more direct damages from the disaster. “Normally, sewer overflows are just discharged into waterways and humans that generate the sewage can avoid the consequences by avoiding the water,” said John Lipscomb of the clean water advocacy group Riverkeeper. “But in this case, that waste has come back into our communities.”

One particular concern is the Gowanus neighborhood in Brooklyn, which abuts a 1.8 mile canal that was recently designated a Superfund cleanup site by the U.S. Environmental Protection Agency due to a legacy of industrial pollution and sewage discharges. While a storm surge of up to 11 feet had been predicted, the confluence of Sandy and a full-moon high tide exceeded expectations: Waters rose a record 13 feet in New York Harbor. Judith Enck, regional administrator for the EPA region that includes New York, told The Huffington Post that preparations for such a pollution event are difficult regardless of how accurate the weather forecast. “Little can be done in the hours or days in advance of major storms that were experienced last night,” said Enck. “Instead, multi-year improvements need to be made. The situation illustrated the need to clean up urban waters and the benefits of a comprehensive Superfund cleanup.” The best officials could do was urge residents to steer clear of the contaminated waters.

While a storm surge of up to 11 feet had been predicted, the confluence of Sandy and a full-moon high tide exceeded expectations: Waters rose a record 13 feet in New York Harbor. A similar post-Sandy scene played out at New York City’s other Superfund site, Newtown Creek, a waterway that forms the border between Brooklyn and Queens. Combined sewage overflows, so-called CSOs, are also nothing new for New York City. A number of older U.S. communities — including a number of East Coast cities affected by Sandy — sit atop antiquated plumbing that carries sewage, industrial wastewater and rainwater together to treatment plants. As little as a quarter-inch of rain can be enough to overburden the multi-use pipes in New York City and trigger a CSO, according to Riverkeeper. “What happened last night in terms of CSO releases is what happens chronically in wet weather events throughout the year,” said Lipscomb, pointing out that 27 billion gallons worth of the mix spills into New York Harbor every year. “You can think about this like an Exxon Valdez accident, but instead of there being one contaminant it’s a zillion contaminants — from floatables to dissolvables to containers of contaminants — and instead of one location, there’s a zillion point sources,” Lipscomb said. “This is a stunning pollution event. I don’t think the harbor has ever taken a hit like today.” http://www.huffingtonpost.com/2012/10/30/hurricane-sandy-sewage-toxic-_n_2046963.html

When our children are sent off to day care – are they breathing in toxic phthalates?

When considering day care, more than a few related topics could come to mind: children, toys, play, and a safe environment are probably some to just name a few. However, although children at day care may be under the supervision of responsible adults and having a great time with their playmates, they may be at risk for a danger most parents would have no idea about — toxic chemicals in the day care environment.

A new study of day care centers found a toxic cocktail of chemicals lurking in the air and dust, including phthalates, chemicals that are so toxic they’ve been banned in toys across the globe.

The research, funded by the California Air Resources Board (CARB), is the first-ever detailed analysis of environmental contaminants and exposures for California day care centers. It covered 40 early childhood education facilities.

“Children are more vulnerable to the health effects of environmental contaminants, and many small children spend as much as 10 hours per day, five days a week, in child care centers,” said study lead author Asa Bradman, associate director of the UC Berkeley Center for Environmental Research and Children’s Health (CERCH).

Phthalates Widespread in Daycare Centers

Phthalates are chemicals commonly used to make vinyl building materials such as flooring soft and flexible.  These building materials are commonly used in schools and day care centers, even though safer biobased alternatives like linoleum are available.

In the new study, phthalates were found in 100% of the air and dust samples inside daycare centers.  The report noted that,

“Phthalate compounds, detected in 100% of the air and dust samples, have been shown to disrupt normal hormone function in animals. There are no health-based benchmarks to evaluate phthalate levels in air. Of all compounds measured in dust, the highest were the phthalates di(2-ethylhexyl) phthalate (DEHP) and butyl benzyl phthalate (BBP), with medians of 172.2 and 46.8 μg/g, respectively.”

Oy.  Every single sample.

Phthalates have no place inside day care centers or schools, and are brought to us by BIG CHEM.  They are harmful to children’s health.  The researchers stated that

“Phthalate compounds are on the California Proposition 65 list as developmental toxins, and have been found to contaminate indoor environments.Studies have associated phthalate exposures with bronchial obstruction, allergies, and asthma in young children, and they are likely endocrine disruptors in humans.”

US EPA: Children Face Highest Exposures to Phthalates

According to the EPA,

“Data from the National Health and Nutrition Examination survey (NHANES) indicates widespread exposure of the general population to phthalates. Biomonitoring data from amniotic fluid and urine have demonstrated that humans are exposed to phthalates in utero, as infants, during puberty, and in adult life, and that people are exposed to several phthalates at once…NHANES detected a DEHP urinary metabolite in 78% of the 2541 samples tested with women having a higher exposure than men. Children have been reported as having the highest exposures; specifically to DEHP, DBP, BBP and DnOP…Children are exposed to phthalates through environmental sources (e.g., air, water, food) as well as consumer products (e.g., toys)…Children’s estimated exposures are often greater than those in adults which may be due to increased intakes of food, water, and air on a bodyweight basis, as well children’s unique exposure pathways such as mouthing of objects and ingestion of non-food items. The 1999-2000 and 2001-2002 biomonitoring data in the Third National Report on Human Exposure to Environmental Chemicals demonstrate that children have the highest exposures to phthalates of all groups monitored, and other biomonitoring data indicate in utero exposures to phthalates.”

Phthalates Banned in Toys in the US and Around the World

Phthalates were banned in toys in the United States in 2008.  Similar bans have been enacted by the states of California, Washington and Vermont.

Restrictions or bans have been placed on phthalates in PVC toys in the entire European Union, Austria, Denmark, Finland, France, Germany, Greece, Italy, Japan, Iceland Mexico, Norway, and Sweden.

While phthalates have been banned in toys, similar protections do not exist for day care centers and our schools.

Insane right?

Why are they still allowed in daycare centers and schools?

Halloween Nightmare

I dreamed that just as I entered a Halloween haunted house the first monster I ran into was Frackenstine.  Just like the book Frankenstein written by Mary Shelley about a creature produced by an unorthodox scientific experiment I noticed that the Frackenstine that stood before me was also made up by combining many parts.  Frackenstines legs turned out to be the Ohio legislature that gave the monster his legs to make his way around Ohio, his torso was made of the Ohio oil and gas industry, his arms were the different state agencies that gave the monster the strength to strong-arm Ohio communities by not allowing citizens or local government to have any say into whether or not they wanted this massive industrial process to destroy their community.  The Frackenstine monster was so big I was having a hard time seeing who or what made up the head  but as I moved farther away from the monster I could see that the monsters head was Ohio’s own governor, Governor John Kasich who has become the mouthpiece and cheerleader for industry.

Down a long dark hallway I came to a closed door, as I opened the door I saw a room full of bubbling cauldrons.  As I looked around the room I saw thousands of Material Safety Data Sheets with all of the toxic chemicals blacked out.  There was also a flashing sign that warned of radiation.  While trying to read all of the signs I was suddenly approached by someone dressing in a hazardous materials moonsuit telling me that bubbling brew was safe and not to worry.  Even though he was dressed in protective garb he informed me that I was not allowed to know what was in the bubbling toxic brew and the door was quickly closed in my face.  As the door closed I could hear the sinister laugh of a crazy person who had spent too much time inhaling the toxic vapors of the bubbling cauldrons full of fracking fluid.

As I continued down the dark hallway I turned a corner and was face to face with a Vampire with blood dripping from his fangs. NO wait, it wasn’t blood dripping, I realized his fangs are drilling rigs that were dripping oil and he is hungry for more and more.  He can’t get enough; he is sinking his rigs into hundreds of thousands of acres of Mother Earth just to see if he can find more oil or gas to feed his needs.  I thought if I can just hold out until dawn the sun would destroy this vampire, but I was so wrong.

As I was about to exit the haunted house I heard the screams of the banshee foretelling the death of life as we know it.  No longer will we have local communities where we can cross the street without worrying about being hit by one of the thousands of trucks or being harassed by out of state workers that have no since of pride for the community.  We face industrial facilities in places where they have no business being in.

But wait, I suddenly realized I was not asleep, I was not having a nightmare.  What I had thought was a horrible nightmare was indeed reality for many communities in Ohio and across the nation that are faced with the nightmare known as fracking.

Let's Debate the Real Facts Tonight-When Jobs Are Raised

Tonight’s debate between President Obama and Mitt Romney is about foreign policy. However, the issue of jobs is going to be injected because that is THE talking point for both candidates. Yet green clean jobs and economic growth is almost never mentioned as if it were a curse word.

Neither candidate is likely to mention the fact, according to a recent report by the Brookings Institute, that sectors like clean energy, green building, and efficient transport employ 2.7 million workers — more than the biosciences and fossil fuel sectors. Furthermore, these jobs actually pay better than an average job. The Brookings report show, yet again, that environmental sustainability isn’t some passing fad or a feel-good exercise, it’s a natural progression of the economy. If we could only get our leaders to pay attention.

Another interesting fact that Brookings reported is that the jobs created from 2008-2009 grew at almost double what the overall economy grew during those same years. An analysis from the Center for American Progress found that clean-energy investments create about 16.7 jobs for every $1 million in spending. Spending on fossil fuels, by contrast, generates 5.3 jobs per $1 million in spending. Why isn’t this being talked about in the debates or on the campaign trail of either candidate? The most important take-away from the report is that the clean economy — which has become a large portion of our overall economy — comes with immense benefits beyond the obvious environmental factors. People will be less exposed to chemicals and other toxins associated with the fossil fuel industry, resulting in less disease, special educational teachers and millions of dollars spent cleaning up the mess.

China is likely to be mentioned in this debate but I’ll bet neither candidate will talk about China’s investments in clean energy. According to the report American firms are losing market share both at home and abroad to competitors from other nations. An enormous part of the answer has to do with China’s ability to channel vast sums of affordable capital into innovative large-scale deployment projects—something that the U.S. continues to struggle with. The numbers speak for themselves. In 2010, China put into place a staggering $54.4 billion in clean energy investments. Of this, asset financing—funding for hard assets like wind farms and solar arrays—accounted for more than $47 billion of the total. By contrast, U.S. private investment in clean energy totaled $34 billion, with just $21 billion or so in asset finance. Now the gap is widening further, with Chinese asset finance investment in at $10.9 billion as compared to just $2 billion in the United States. Could this investment by China be because China isn’t run by or owned by the large oil and gas industries?

The recent report confirms that these exciting clean-energy industries really are growing as fast as we think they are. The challenge is to get to our elected leaders and those running for election and demand that they stop talking about out-dated energy options and job creation and begin moving on the investments that will provide good wages, environmentally safer and economically better futures for all Americans.

Pioneering Green Carpeting Manufacturer Interface Ends its Defense of PVC

After years of defending PVC as an ecologically sustainable industrial material, Interface, one of the world’s largest carpet manufacturers and a pioneer in sustainable business, has announced that it will be eliminating virgin PVC from its entire product line by 2020.

The announcement comes as a welcome end to a long-standing conflict between the company and its core constituency of ecologically-minded consumers and businesses. In recent years, other major carpet manufacturers including Shaw and Milliken have phased PVC out of their product lines, but Interface had not followed suit. In a recent article in GreenBiz, the company’s sustainability team writes about the painful but productive process of incorporating vinyl’s full life-cycle impacts into its definition of sustainability.

Vinyl is the plastic environmentalists love to hate because of its life-cycle toxicity issues, which occur both upstream (emissions from plastic production) and downstream (if it gets burned under uncontrolled conditions). In addition, PVC always contains other chemical additives, some of which (e.g., heavy-metal stabilizers) may be quite toxic. While our Restricted Substances List adequately screens out toxic additives, it is not designed to account for these life-cycle toxicity issues.

As an early champion of lifecycle assessment (LCA), we were confident that we had a tool to account for the life-cycle of PVC. And while LCA has proven to be a reliable tool for more holistic decision-making, especially for considering carbon footprint or water impacts, it is notoriously weak at evaluating human health impacts like toxicity.

Even with robust life-cycle toxicity data (such as the chlorinated emissions from a PVC supplier), plotting it in a graph next to greenhouse gas emissions is scientifically meaningless and emotionally explosive, given that potential health impacts are far more personal and comprehensible.

Though it spent years defending PVC, in 2008 Interface began working more closely with its critics and adjusting its industrial criteria. The policy it has developed eliminates the use of virgin PVC by 2020, while reusing and diverting from the landfill millions of pounds of PVC carpet-backing currently in the waste-stream. It’s a major step forward for the carpeting industry, and we at CHEJ are glad to have Interface in our corner.

For me personally, first learning about Interface’s story was an “ah-ha” moment. I’d seen the movie “The Corporation,” in which Interface’s founder and long-time CEO, the late Ray Anderson, speaks dramatically of his conversion to an ecological approach to business. He realized that Interface’s extraction and production practices amounted to “the way of The Plunderer, plundering something that’s not mine, something that belongs to every creature on Earth.” I later read Natural Capitalism by Paul Hawken and Amory and L. Hunter Lovins, and learned with great excitement about the ways in which ecological thinking had transformed not only the contents of Interface’s carpet, but their whole business model.

Anderson and his team realized that businesses don’t want to own carpet — they want the service of floor covering. They combined this insight with the fact that when standard broadloom carpet is replaced due to worn spots, traditionally once every ten years, huge amounts of perfectly good carpet gets torn out and landfilled. There is more carpeting in US landfills than almost any other product, much of it toxic.

In response to these two realities, the company fundamentally rethought their business approach. Interface created modular carpet tiles, allowing worn areas to be replaced individually; they then leased these tiles to businesses rather than selling them, taking the worn tiles back to the factory; and they developed a higher quality, less toxic, resilient carpet product called Solenium to cover the tiles, which could be completely remanufactured into itself, retaining the value of the materials and further reducing waste.

Reading about this type of holistic, innovative approach to industry was eye-opening. It was proof that businesses can make money by being smart and following their values, by protecting their customers’ health and the environment rather than endangering it. Interface is to be commended for finally incorporating PVC-elimination into its vision. I look forward to seeing where that vision it takes the company next.

BPA in Receipts – The chemical that’s everywhere, or so it seems

It’s very likely that you’ve heard of a chemical called BPA or bisphenol A. It’s been in the news because it’s an endocrine disrupting chemical used in making plastic products and in the lining of metal cans. The problem is that BPA leaches out of plastic bottles, canned foods and other products and gets into the food and drink. Trace amounts of BPA have been found in the urine of at least 90% of Americans.  BPA mimics the hormone estrogen in the body and has been linked to reproductive and developmental abnormalities as well as other adverse health effects.

[fusion_builder_container hundred_percent=”yes” overflow=”visible”][fusion_builder_row][fusion_builder_column type=”1_1″ background_position=”left top” background_color=”” border_size=”” border_color=”” border_style=”solid” spacing=”yes” background_image=”” background_repeat=”no-repeat” padding=”” margin_top=”0px” margin_bottom=”0px” class=”” id=”” animation_type=”” animation_speed=”0.3″ animation_direction=”left” hide_on_mobile=”no” center_content=”no” min_height=”none”]

Source: American Chemical Society

Concerns about these adverse health effects led Canada to define BPA as a toxic substance and 11 states to ban its use in baby bottles and sippy cups. The FDA followed suit in July of this year. Concerns remain however about BPA leaching into infant formula, food and beverages. Approximately eight billion pounds of BPA are used each year worldwide.

Although diet is the primary route of exposure to BPA, research has shown that it can also be absorbed though the skin in a less familiar way – the handling of receipts of all kinds. BPA is the primary chemical used in cash register and thermal receipts commonly used in stores, ATM machines, gas stations, various tickets, and many other uses. BPA is used as a color developer for the printing dye. It’s applied as powder coating that acts in the presence of heat to produce an image without ink. The problem here is that the chemical is not bound to the paper, so it rubs off when you handle the receipt. It gets on your fingers and quickly gets into your blood stream. If you handle receipts every day, and it accumulates in the body, you increase your risk. This is especially a concern for workers who handle receipts all day long, or for pregnant women.

While there’s no way to tell if a receipt contains BPA or not, a number of studies have tested receipts for BPA. One study reported in the New York Times of 103 thermal receipts collected from cities in the U.S., Japan, South Korea and Vietnam in 2010 and 2011 found 94% of the receipts to contain BPA. All of the receipts in the U.S. had traces of BPA, even some marked as BPA-free. A study by researchers in Boston found 8 of 10 cash register receipts had BPA, and a study by the Environmental Working Group in 2010 found 14 of 36 receipts collected from fast food restaurants, retailers, grocery stores, gas stations and post offices tested positive for BPA.

Although studies in animals have found that very low concentrations of BPA can produce adverse effects, it’s unclear what level of exposure in people can produce adverse effects. It’s also unclear how much exposure from thermal receipts contributes to a person’s total exposure to BPA. Diet remains the primary route of exposure. It is clear, however, that there are readily available alternatives to BPA and this is another source of chemical contamination that can easily be eliminated.
