Air Pollution: The Silent Killer

Photo credit: Freepik

By Leila Waid.

Air pollution poses a major risk to human health and is the fourth leading cause of death globally. Although air pollution regulations, such as the Clean Air Act, have drastically reduced the number of deaths and illnesses in the United States, there is still an unacceptably large number of deaths from air pollution. For example, two in five Americans live in areas that are above the threshold for safe air pollution exposure, as set by the EPA. 

Air pollution refers to particles, gases, and contaminants not found in pure air. They include dangerous material that is introduced into the atmosphere, usually through human activity, such as burning fossil fuel. The five air pollutants of highest concern – and those monitored under the National Ambient Air Quality Standards – are tropospheric ozone (ground-level ozone or the “bad” ozone), particulate matter, carbon monoxide, nitrogen oxides, sulfur dioxide, and lead. Of the six pollutants, particulate matter is one of the biggest threats to health. Particular matter is divided into two categories: PM10 and PM2.5. PM10 are particles less than 10 micrometers in size, and PM2.5 are those less than 2.5 micrometers. 

The World Health Organization has set the limit for PM2.5 at 5ug/m3 (microgrammes per cubic meter). Only 0.001 percent of the world meets this threshold. And in the U.S., the majority of Americans are exposed to much higher levels than that standard. Even more alarmingly, some researchers argue that there is no safe level of exposure to PM2.5. Various peer-reviewed studies, such as this epigenetic study, found that even exposure below the strict WHO standard can still cause adverse health effects. 

PM2.5 is a major environmental health concern because it is ubiquitous in the environment, causing dangerous levels of exposure for most of the world, and the microscopic and irregular shape of these particulates leads to them evading the body’s defense systems. Compared to PM10, PM2.5 is much more likely to enter the bloodstream. In general, the structure of our lungs – particularly the bronchioles and the alveoli – does a great job of expelling the foreign particles we inhale. However, PM2.5 can evade these defense mechanisms and cause havoc on our bodies and health. 

What are the health effects of PM2.5? The Health Effects Institute estimates that, globally, 40% of all Chronic Obstructive Pulmonary Disease (COPD) deaths and 20% of all diabetes deaths are associated with exposure to PM2.5. And in the U.S., it is estimated that PM2.5 attributed to 47,800 deaths in 2019. 

Air pollution is a silent killer. With the criteria pollutants, such as PM2.5, being invisible to the human eye, we don’t take this threat as seriously as we should. We utilize an out-of-sight, out-of-mind philosophy with air pollution, and most of us take for granted how vital clean air is to our health and well-being. Every day, we breathe in harmful chemicals from fossil fuel combustion and then don’t even realize the detrimental health effects of those actions. The adverse health effects of air pollution can appear as cancer, heart disease, respiratory issues, or a myriad of other medical diagnoses without the affected individual ever realizing the outsize role that air pollution played in that health outcome.

EPA Passes Regulations for Forever Chemicals: Good News and Bad News

Photo credit: Demphoto

By Stephen Lester.

Earlier month, the US Environmental Protection Agency (EPA) finalized drinking water standards for a group of substances known as Forever Chemicals. These chemicals include PFOA, PFOS, PFNA, PFHXs, PFBS, and GenX and are generally described as polyfluoroalkyl substances (PFAS). PFAS chemicals are present everywhere in the environment, degrade very slowly and posed health risks to people who are exposed to them. They are called forever chemicals because they break down so slowing that they are around for centuries, essentially forever.

This new regulation requires that these forever chemicals be added to the substances that EPA requires all public drinking water systems to routinely monitor. Some water companies will start testing for PFAS in drinking water as early as 2027 in 3 years, but these restrictions don’t go into effect until 2029, five years from now. This regulation does not apply to private or individual wells, just to large public water systems.

While it’s good news that PFAS chemicals will be restricted in drinking water by 2029, this decision also highlights the slow cumbersome way that chemicals are regulated in this country. Although EPA made clear that there are significant and severe adverse health effects associated with these chemicals, the agency did not restrict their production or use in consumer products, just their presence in drinking water, and not for another 5 years. So, Dupont, 3M as well as other companies will continue to make these chemicals for use in consumer products. Furthermore, this new regulation only applies to 5 of the thousands of different PFAS compounds that have been identified.

Why does this make any sense? It certainly does not make any public health sense. EPA acknowledges the adverse health effects of these chemicals at extremely low levels, to the point where some researchers feel that there is no safe level of exposure to PFAS chemicals, yet EPA takes no action to restrict the production of these substances and gives water companies five years to meet its new standards. And for the companies that manufactured these chemicals – primarily DuPont (and several subsidiaries) and 3M – there’s no action against them or accountability for producing these substances for more than 50 years, even though for decades they opposed any regulatory action by EPA.

Over these years of delay, these companies slowly began moving away from the  PFAS chemicals that were targeted as “bad actors” – PFOA and PFOS – and began producing and using other PFAS chemicals about which virtually nothing was known about their toxicity. EPA has allowed this to happen even though the adverse health effects for most of these substances are not known. Somehow EPA seems good with issuing no restrictions on the production of potentially toxic consumer products and instead offers general advice to the public on steps they can take to avoid PFAS chemicals if they choose to do so.

There is something seriously wrong with our system for regulating toxic chemicals when the companies that use dangerous toxic chemicals to make consumer products for profit get off Scot free and the EPA offers advice to individuals on how to avoid these toxic products.

Industry began using these polyfluoroalkyl substances in the 1940s in consumer products such as nonstick cookware (Teflon) and in food packaging, to waterproof clothes, stainproof furniture and in certain manufacturing processes. They were also widely used in firefighting foams to extinguished fires, especially at airports and on training grounds for firefighters. PFAS chemicals gained public notoriety about 10 years ago when they began showing up in drinking water at military bases, such as the Pease Air Force Base in Portsmouth, NH. The US military estimates that there are over 600 military bases with PFAS contamination.

The adverse health effects associated with these forever chemicals include reproductive effects; developmental effects such as low birth weight, bone variations, and behavioral changes; damaged immune function such as reduced ability to fight infections; interference with the body’s natural hormone functions, including the thyroid; kidney and testicular cancer; liver damage; and increased cholesterol.

1,4-dichlorobenzene (1,4-DCB)

Toxic Tuesdays

CHEJ highlights several toxic chemicals and the communities fighting to keep their citizens safe from harm.

< Back to Toxic Tuesdays

1,4-dichlorobenzene (1,4-DCB)

1,4-dichlorobenzene (1,4-DCB) – also known as p-dichlorobenzene (p-DCB) – is a colorless solid chemical that readily evaporates into the air. 1,4-DCB does not occur in nature, and it is often produced for use in deodorants or disinfectants because it has a strong odor that humans can smell at very low concentrations. It is commonly used in household products like mothballs and deodorizing sprays. It also has industrial uses as a pesticide ingredient and a precursor to commercial dyes. 1,4-DCB can enter the environment through its household uses, pesticides, and industrial waste disposal. 1,4-DCB mostly enters the environment as a vapor, and people are likely to inhale it in homes and buildings where it is used. Solid 1,4-DCB can also bind to soil and remain there for long periods of time, but people are less likely to be exposed to it in this way.

Inhaling high concentrations of 1,4-DCB can cause irritation or burning sensations in the eyes and nose. It can also cause coughing, nausea, difficulty breathing, dizziness, headaches, and liver dysfunction. Touching products that contain 1,4-DCB can also cause burning sensations on the skin. In studies of laboratory animals, 1,4-DCB exposure caused liver, kidney, and blood defects as well as liver cancer. The US Department of Health and Human Services and the International Agency for Research on Cancer both classify it as being reasonably anticipated to cause cancer.

Because of the danger to human health, the Environmental Protection Agency has set a maximum 1,4-DCB concentration that can be present in drinking water without observing adverse health effects. The European Union has gone even further, banning use of 1,4-DCB in mothballs and air fresheners because of its potential to cause cancer. Similar regulation in the US could protect more people from the health risks of 1,4-DCB exposure.

Barium

Toxic Tuesdays

CHEJ highlights several toxic chemicals and the communities fighting to keep their citizens safe from harm.

< Back to Toxic Tuesdays

Barium

Barium is a silver-colored metal which is found in the earth in compounds with other elements. Many barium compounds have industrial uses: barium sulfate is used as a drilling lubricant by the oil and gas industries to facilitate drilling through rock; barium carbonate is a rat poison; and barium oxide is used in the production of electronics and glass. Barium can enter the air through the production of barium-containing compounds and the improper disposal of barium-containing waste. It can then enter the soil and water. Barium compounds that do not dissolve in water can persist in the soil and water for a long time.

People are most likely to be exposed to barium by drinking contaminated water. Barium compounds that do not dissolve in water – like barium sulfate and barium carbonate – are not known to be harmful to human health. However, barium compounds that do dissolve in water – like barium chloride and barium hydroxide – can harm human health because they release barium ions into the body. Barium ions interfere with the normal electrical impulses generated in the brain, muscles, and heart. Exposure can cause gastrointestinal dysfunction such as vomiting, diarrhea, and abdominal cramps. It can also cause anxiety, disorientation, difficulty breathing, decreased blood pressure, numbness, muscle weakness, and paralysis. The eyes, immune system, respiratory system, and skin can also be damaged by barium exposure. The Environmental Protection Agency (EPA) has set a limit on how much barium can safely be in drinking water, but almost 800 Superfund sites are known to have barium contamination, suggesting that there may be potential for barium exposure in some communities.

Commitment to Tackling Risks Posed by Toxic Chemicals

Photo credit:  Ivan Bandura/Unsplash

Reshare by EHN Curators

In a recent development highlighting a personal commitment to addressing the perils associated with toxic chemicals, the current administration has intensified efforts to mitigate environmental and health risks.

According to Chris D’Angelo’s coverage in The Huffington Post:

  • The administration has initiated measures to limit hazardous waste and chemical exposures, including restrictions on open burning of waste explosives and the evaluation of cancer-causing chemicals.
  • Despite these efforts, the handling of the East Palestine, Ohio, train derailment, involving the burning of vinyl chloride, has drawn criticism for its potential health and environmental impacts.
  • The EPA’s proposed rule to limit the open burning of waste explosives aims to protect communities but does not directly address the concerns raised by the East Palestine incident.

“Toxic smoke, thick with poison, spreading through the air and into the lungs of our troops. When they came home, many of the fittest and best warriors that we sent to war were not the same — headaches, numbness, dizziness, cancer. My son Beau was one of them.”

— President Joe Biden

Hazardous waste and toxic chemicals can wreak havoc on public health and ecosystems. Chemicals that seep into soil and waterways can disrupt habitats, harm wildlife, and contaminate food chains. This not only affects biodiversity but can also compromise the resources people rely on, like clean drinking water and productive agricultural land.

One Billion Additional Dollars for Superfund – It’s Still a Drop in the Bucket

Photo Credit: Jane Tyska/Digital First Media/East Bay Times via Getty Images

By Sharon Franklin.

The Superfund program was established in 1980 to clean up sites contaminated sites with hazardous substances.  On February 27, 2023 CBS News reported that the Environmental Protection Agency (EPA) will attempt to speed the cleanup of 85 ongoing Superfund projects across America by infusing $1 billion of funds into the program. The EPA also identified twenty-five (25) toxic waste sites in 15 and two territories states that will get a funding boost. These one billion dollars represent the third and last installment of the $3.5 billion allocated under the 2021 infrastructure law signed by President Biden.

These sites can be found via the Superfund Enforcement Cleanup Work Map. A few of the long-contaminated sites slated for cleanup are:

  • A former smelting plant in East Helena, Montana.
  • An old textile mill in Greenville, South Carolina.
  • A beach area was blighted nearly 60 years ago by lead battery casings and other toxic material used to build a seawall and jetty in Raritan Bay, Old Bridge, and 2 other sites in New Jersey.
  • Four sites including West Hazleton at the former Valmont Industrial Park in Pennsylvania.
  • Three sites including the Clearlake Oaks Sulphur Bank mercury mine in California.

As many affected communities know first-hand, the Superfund program was not funded for years but has been replenished after Congress included a “polluter pays” tax in the 2021 infrastructure law. “The tax took effect in 2022 and is set to collect up to $23 billion over the next five years,” said New Jersey Democrat Representative, Frank Pallone, who pushed for reinstatement of the tax in the 2021 law.For New Jersey residents, the Superfund Program is very important because New Jersey has more Superfund sites than any other state, and half of its 9.3 million residents live within three miles of a Superfund site. Pallone also said, “Superfund sites threaten public and environmental health across the country,” including New Jersey, “but with today’s announcement, the Bipartisan Infrastructure Law is continuing to deliver on the promise we made to clean up backlogged sites and give our communities the peace of mind they deserve.”

Pallone’s remarks on Superfund concluded by saying “I really believe that all of our communities across the country deserve to enjoy their towns and use their space without fear of the health risks that come with living near a Superfund site,’‘   “Corporate polluters — not taxpayers— should pay to clean up the messes they created.”

As encouraging as this windfall is, we need to recognize that only 85 of the nation’s 1,300 Superfund site would be addressed through this program.

Acknowledging the Limits to Assessing Low Dose Mixtures of Toxic Chemicals​

Acknowledging the Limits to Assessing Low Dose Mixtures of Toxic Chemicals

Approximately 1 year ago a Norfolk Southern train carrying more than 150 cars, many of which containing toxic chemicals derailed in East Palestine, OH. Thirty-eight of the train cars derailed and a decision was made by Norfolk Southern to burn the contents of 5 tanker cars containing vinyl chloride and other toxic chemicals. This unleashed a huge black cloud of particulates that enveloped the surrounding neighborhoods and farms in both OH and PA.

Immediately after the burn, people in East Palestine began reporting adverse health symptoms including, headaches, nose bleeds, skin rashes, central nervous symptoms, thyroid problems and more. These and other adverse health problems have continued to plague the residents of this rural midwestern town.

EPA responded immediately by telling people that everything was alright, that there was no cause for alarm. EPA’s testing found no levels of “concern.” But the people in East Palestine could not accept this narrative because they knew things were not right. They knew the health effects they were suffering were real. They knew that EPA was not telling them the truth.

If EPA were honest with the people at East Palestine, they would have told them that they don’t understand why people are continuing to report so many illnesses while their data tells them that there should not be any adverse health problems in the community.

But if EPA did that, if they acknowledged how little is known about the link between adverse health effects and exposures to mixtures of chemicals, the people of East Palestine would demand action in the face of these uncertainties. Action like paying for people to relocate from the area so that they can stop being exposed to the toxic chemicals which are still in the air, getting the health care they need and moving on with lives.

It is clear from the situation in East Palestine that very little is known about how people respond to exposures to low level mixtures of toxic chemicals. It’s time to acknowledge that the scientific understanding does not exist to explain what is happening to the health of the people in East Palestine or other communities exposed to toxic chemicals. It’s time to recognize that we cannot rely on traditional toxicology to answer the questions people have about their exposures to low level chemical mixtures.

In an editorial about evaluating low dose exposures, Linda Birnbaum, former director of the National Institute for Environmental Health Sciences, described the traditional approach to evaluating health risks as “antiquated” and said that it needs to be replaced by a “better understanding of the actual characteristics of modern environmental chemicals.” Birnbaum went on to say that “It is time to start the conversation between environmental health scientists, toxicologists, and risk assessors to determine how our understanding of low doses effects and non-monotonic dose responses influence the way risk assessments are performed for chemicals with endocrine disrupting activities.”

It’s time to acknowledge that the tools we have are not able to answer the questions people ask about their exposures to toxic chemicals and give people the relief they are asking or, whether it’s cleanup, relocation, health care or something else.   

This is exactly what the government did for the Vietnam veterans exposed to Agent Orange; for the atomic bomb victims exposed to radiation fallout; for the 9/11 first responders in New York City; for the soldiers exposed to burn-pit smoke in Iraq and Afghanistan; and for the marines and their families at Camp Lejeune, North Carolina who drank contaminated water.

In each of these instances, the government recognized that the science linking exposure and health outcomes was impossible to assess and instead of requiring proof of cause and effect, they said, enough, we need to take care of our own and moved to a presumptive scientific approach that allowed veterans and first responders to get health care and other compensation. We should do the same for the people of East Palestine and in hundreds of other communities that have been exposed to low level mixtures of toxic chemicals.

It’s Time to Do Right by the People in East Palestine, OH – and Elsewhere

Photo credit: CNN

By Stephen Lester.

Nearly 10 months ago, a Norfolk Southern train with more than 150 cars, many of which contained toxic chemicals, derailed in East Palestine, OH. Thirty-eight of the train cars derailed and a decision was made by Norfolk Southern to burn the contents of 5 tanker cars containing vinyl chloride and other toxic chemicals. This unleashed a huge black cloud full of particulates that enveloped the surrounding neighborhoods and farms in both OH and PA.

Actions like paying for relocations so that they can stop being exposed to the toxic chemicals that are still in the air and getting the health care they need to move on with their lives.

The people in East Palestine deserve better. So do hundreds of other communities across this country where people have similarly been exposed to low levels mixtures of toxic chemicals. It is clear from the situation in East Palestine that very little is known about how people respond to chemical exposures, especially to low level mixtures. This is evident when the EPA and other public health agencies who rely on traditional toxicology and risk assessment are telling the people of East Palestine that everything is safe when it clearly is not.

It’s time to acknowledge that the scientific understanding does not exist to explain what is happening to the health of the people in East Palestine. It’s time to recognize that we cannot rely on traditional toxicology to answer the questions people have about their exposures to low level chemical mixtures. It’s time to do the right thing by the people in East Palestine and by hundreds of communities across the U.S. where people are being exposed to low level mixtures of toxic chemicals. It’s time to acknowledge that the tools we have are not able to answer the questions people raise about their exposure to toxic chemicals and give people the relief they are asking for, whether it’s cleanup, relocation, health care or something else.   

It’s what the government did for the Vietnam veterans exposed to Agent Orange; for the atomic bomb victims exposed to radiation fallout; for the 9/11 first responders in New York City; for the soldiers exposed to burn-pit smoke in Iran and Afghanistan and other overseas locations; and for the Marines at Camp Lejeune, North Carolina who drank contaminated water. Do the people of East Palestine deserve anything less than the soldiers and first responders who protect this country?

In each of these instances, the government recognized that the science linking exposure and health outcomes was incomplete and instead of requiring proof of cause and effect, they said, “Enough, we will take care of our own.” They moved to a presumptive scientific approach that allowed veterans and first responders to  health care and other compensation. We should do the same for the people of East Palestine and in hundreds of other communities that have been exposed to low level mixtures of toxic chemicals.

When We Fight, We Win!

By Sharon Franklin.

In July 2023, I wrote the blog, “There’s An Ethylene Oxide (EtO) Health Emergency in South Memphis, Tennessee.” In it, I discussed the air pollution created by the Sterilization Services of TN (SELC) in Memphis, Tennessee. According to an August report by Adrian Sainz from AP News, SELC will officially be closing its Memphis plant!

As background, SELC is a medical equipment sterilizing plant that has been emitting hazardous air pollution since 1976 (permitted to do this since 1985). Ethylene oxide (EtO) is used to clean catheters, syringes, pacemakers, plastic surgical gowns, and other items. On August 24, 2023, the Memphis Community Against Pollution, an environmental watchdog group requested a meeting. This meeting was in response to public concern about the chemical emissions and to petition the Shelby County Health Department for an emergency air pollution order.

Even the EPA understands that the plant’s use of EtO to sterilize medical equipment and materials could lead to cancer and other health risks. While short-term or infrequent exposure to EtO does not appear to pose a health risk, the EPA determined that long-term or lifetime exposure to the colorless and odorless gas could lead to a variety of health problems, including lymphoma and breast cancer. For 30 years, the EPA has regulated EtO emissions; however, in 2016 new scientific information revealed that the chemical is more toxic than previously reported. In April 2023, the EPA proposed limiting the use of EtO after finding a higher than expected cancer risk at facilities that use it for sterilizations.

The EPA claims that it is working with commercial sterilizers to take appropriate steps to reduce emissions. It said that its proposal will reduce EtO by roughly 80% by targeting 86 medical sterilization facilities across the country. The companies will also have to test for the antimicrobial chemical in the air and ensure their pollution controls are working properly. EPA Administrator Michael Regan stated that the “EPA is taking action to ensure communities are informed and engaged in [all] efforts to address ethylene oxide…” The agency further stated that “it is committed to addressing pollution concerns associated with [EtO] ‘in a comprehensive way that ensures facilities can operate safely in communities while also providing sterilized medical supplies.’”

Raul Garcia from Earthjustice argued that “[now] that EPA has new information on precisely where the worst health threats are, the agency must use its full authority to… require fenceline monitoring at these facilities [and] issue a strong new rule.” She also stated that, “No one should get cancer from facilities that are used to sterilize equipment in the treatment of cancer.”

Amanda Garcia, Senior Attorney at the Southern Environmental Law Center, recognized that the Sterilization Services of Tennessee closing the Memphis plant is “a major victory for nearby neighborhoods who have been fighting for cleaner air.” She is “pleased that [the community] may soon be able to breathe easier.”

East Palestine, OH: A Scientist Speaks Out

By Stephen Lester.

East Palestine, OH: A Scientist Speaks Out 

The situation in East Palestine, OH remains very frustrating for many residents. They are trying to make sense of the contrast between what EPA tells them with the many adverse health symptoms they are experiencing firsthand. Many residents continue to suffer from nose bleeds, headaches, skin rashes, thyroid problems and more caused by the horrific derailment and subsequent intentional burning of five tanker cars full of vinyl chloride. A highly toxic chemical known to cause cancer, liver damage, central nervous system and other adverse health effects. EPA continues to tell people that everything is fine and Norfolk Southern, the train operator, is tired of paying for temporary housing which some people have used to move out.

The letter below, reprinted in its entirety, is from an independent scientist who has taken air samples from inside the homes in of some people still living in East Palestine. This will give you some idea what people there are continuing to go through. The letter was addressed to the Ohio Senators Sherrod Brown and J.D. Vance and Ohio representative Bill Johnson. EPA has refused to respond to these independent test results and continues to ignore pleas for additional testing in homes in East Palestine. 

Senator Sherrod Brown, J.D. Vance

Congressman Bill Johnson

(sent by email)

Hart Senate Office Building, 201 2nd St NE, Washington, D.C. 20002

June 17, 2023

Dear Senators and Congressman representing Ohio:

I am a professor at Purdue University evaluating health risks of conditions that impact people and businesses in and around East Palestine, Ohio. I want to share important findings with you. After my June 10-12 investigation in East Palestine, I have serious concerns for the safety of children, adults, and businesses. During this, my sixth field investigation, I discovered, again, that acute chemical exposures are occurring inside some residential and commercial buildings near the derailment site and along the contaminated Sulfur Run. I provide four recommendations below.

There are still acute health threats inside buildings that agencies have yet to eliminate. Several buildings around the derailment site and along Sulfur Run still have the characteristic odor of chemical contamination. I have smelled it firsthand and we have been doing nearby environmental testing. Last week some occupants indicated that they became ill and have been avoiding certain buildings even after airing them out repeatedly. Some occupants have paid for indoor air testing which revealed butyl acrylate exceeding the ATSDR screening level, soot was present, and other chemicals present (e.g., ethylhexyl acrylate, benzene). Other occupants do not have financial ability to pay for indoor air testing, but I can confirm the odor was present. Norfolk Southern contractors did visit some buildings in February using inadequate air testing devices,[1] and in one case, their team left the building because of the unpleasant odor they encountered. Some occupants told me that Norfolk Southern said they will not help them because there is legal action against them. Some building occupants have told me they cannot spend more than 2 to 5 minutes inside their building without experiencing side effects. In February/March, the East Palestine Municipal Building (85 N. Market Street), where town council meets, was contaminated with chemicals from Sulfur Run. Agencies found chemicals entering through unplugged drain pipes beneath the building. This was corrected, but contamination in other residential and commercial buildings remains.

Actions needed are to:

  1. Decontaminate all residential, commercial, and government buildings surrounding the derailment site and along Sulfur Run. This will help maintain anonymity.
  2. Conduct chemical testing inside these buildings for soot and over several weeks for volatile organic compounds (VOC) and semi-volatile organic compounds (SVOC).
  3. Inspect and eliminate pathways where chemicals enter buildings from the Sulfur Run culverts that go underneath and alongside buildings (i.e., building pipes, drains, cracked concrete, sumps, etc.).

Evidence shows that this disaster has repeatedly exceeded the scientific and organizational capability of the USEPA and other agencies involved. You may consider recommending:

  • The assembly and charging of an independent team of public experts to advise decision makers about scientific issues with this disaster. Areas of expertise needed are air quality, water quality, materials, civil engineering, environmental engineering, mechanical engineering, public health, environmental health, epidemiology, groundwater, risk assessment, among others.

Please do not hesitate to contact me. I can be reached at awhelton@purdue.edu.
