Acrolein

Acrolein is a toxic chemical that presents itself as a clear to yellowish liquid that evaporates quickly and is highly flammable. As it vaporizes, it has an unpleasant smell and tends to accumulate in low areas since it is heavier than air. Acrolein is used as a precursor ingredient in many different kinds of manufacturing industries including plastics, paint, leather finishings, and paper coatings. It is also used as a biocide to control plant and algae growth in water systems.

Acrolein exposure usually occurs in the form of inhalation. Acrolein is formed from the combustion of certain organic compounds. As such, it is commonly formed from the burning of fossil fuels, animal and vegetable fats, and tobacco. It is a common, albeit minimal, by-product of forest fires.

The health effects of short-term exposures to acrolein are fairly well understood. Acrolein is severely irritating to skin, eyes, and mucous membranes. If inhaled, it causes respiratory distress, an asthma-like reaction, and delayed pulmonary swelling. Contact with the skin or eyes produces irritation and lacrimation, and can result in chemical burns.

The long-term health effects of acrolein are much less studied. There are some indications that prolonged exposure can cause respiratory sensitization, a process through which exposure to a chemical leads to hypersensitivity of the airways when exposed again to the same or similar chemicals. Potential adverse reproductive effects or links to cancer have not been explored well enough to draw any conclusions.

It is perhaps this uncertainty over long-term health effects that most concerns residents of East Palestine, OH. After the train derailment dumped more than 1 million pounds of various industrial chemicals in the community, authorities responded by removing some of the contamination and performing controlled burns on the rest. These activities have released dangerous levels of acrolein into the air, as an analysis of EPA data by Texas A&M researchers revealed. Despite accurately assessing the immediate health impacts of acrolein on the community, it is a shame that the same researchers then downplayed the risks of prolonged exposure by saying that “it would take months, if not years, of exposure to the pollutants for serious health effects.” This is simply not true, as we have very little information about long-term exposure to even low levels of acrolein. The situation in East Palestine is extremely worrisome, and researchers downplaying the health risks the community is facing is very counterproductive to the situation.

From Texas to New Jersey – The perilous transport of Vinyl Chloride that puts us all at risk

Photo source: https://www.post-gazette.com/local/2023/02/07/vinyl-chloride-east-palestine/stories/202302070109

By Leila Waid.

Recently, Toxic Free Future (TFF) released a research report on how much vinyl chloride is transported through the U.S. daily. Vinyl chloride is a carcinogenic chemical used to make PVC plastic products. Over the past year, vinyl chloride has constantly been mentioned in the news, partly due to the train derailment in East Palestine, Ohio, last February. The toxic burn of vinyl chloride and other hazardous material resulted in the immediate evacuation of residents within a one-mile radius and has plagued the community with fears and uncertainties about their health since then.

Notedly, the Norfolk Southern train derailment was not the only time a vinyl chloride contamination occurred due to a train accident. In 2012, Paulsboro, New Jersey, experienced a similar disaster. In that community, residents also faced exposure to vinyl chloride after a train accident occurred.

TFF set out to quantify how many people live in the vicinity of the trains that carry this toxic material every day. How many people live their day-to-day lives not realizing that the disasters that hit East Palestine and Paulsboro are not some far-away tragedy that couldn’t possibly happen to them but are instead closer to home than they could have ever imagined? TFF’s report highlights the shocking reality that many live near these train tracks where this toxic material is constantly being transported. The study analyzed the train route of OxyVinyls – a company that was involved in both of the train derailments discussed above – because they have the furthest distance between the procurement site, in Texas, and the PVC manufacturing plant, in New Jersey.

Shockingly, TFF’s report found that over three million individuals, of which 670,000 are children, live within a one-mile radius of the train routes carrying this extremely toxic chemical. Over one year, 1.5 billion pounds of the toxic chemical are carried across train tracks. And 36 million pounds of the chemical is being transported at any given point across the entirety of the U.S.

Of course, someone might think to argue, “I don’t live near the train tracks, so this doesn’t affect me.” However, even individuals not directly in the vicinity of the train tracks still experience adverse effects from the production and use of vinyl chloride. The first reason this affects everyone is that vinyl chloride production releases air pollution, which can travel great distances and cause various health issues. The second reason this issue should concern everyone is that vinyl chloride and PVC production releases over three metric tons of greenhouse gas, further exacerbating the climate crisis. Even the extraction process necessary for vinyl chloride is harmful to the environment. Hydrofracking has a variety of environmental contamination concerns and also releases methane – a potent greenhouse gas. Even abandoned fracking wells have been found to emit methane.

So, how do we address this issue? First, advocate your policymakers for stronger railroad regulations so that other accidents like those in East Palestine or Paulsboro do not occur. Second, pressure government action and stronger EPA regulation around vinyl chloride production. And third, vote with your wallet. Do not purchase materials made out of PVC plastic and pressure retail stores, such as the Home Depot, to phase out selling PVC products.

Trihalomethanes (THMs)

Trihalomethanes (THMs)

Trihalomethanes (THMs) are a class of chemical compounds which contain three halogen atoms. Common THMs include chloroform, fluoroform, and chlorodifluoromethane. While THMs are used in some industrial processes like refrigeration, people are most likely to be exposed to them through drinking water. Most water utilities use small amounts of chlorine as a disinfectant to keep water supplies clean. While adding chlorine is generally accepted to be an important practice to protect public health, this chlorine can react with organic matter in the water and create THMs. Drinking contaminated water is generally considered to be the most serious route of exposure to THMs, though one study has found that bathing with contaminated water causes even higher exposure. THMs are odorless and flavorless, so people may not know if they have been exposed.

Many types of THMs have adverse health effects upon exposure, and there are four that are known to be particularly harmful to human health:

  1. Chloroform is known to cause lung, liver, and kidney damage, and in high doses can lead to death. In studies of laboratory animals, drinking chloroform-contaminated water caused liver and kidney cancer. The Environmental Protection Agency (EPA) classifies it as a likely cancer-causing agent in humans. 
  2. Bromoform can cause neurological impairments, unconsciousness, and death. In studies of laboratory animals, drinking bromoform-contaminated water caused liver and kidney cancer. EPA classifies it as a probable cancer-causing agent in humans.
  3. Dibromochloromethane is less well understood, but in studies of laboratory animals, drinking contaminated water caused liver and kidney cancer. EPA classifies it as a possible cancer-causing agent in humans.
  4. Bromodichloromethane is known to cause liver, kidney, and immune system damage. It can also cause reproductive system damage and lead to miscarriage and low birth weight. In studies of laboratory animals, drinking bromodichloromethane-contaminated water caused intestinal, kidney, and liver cancer. EPA classifies it as a probable cancer-causing agent in humans.

Because of the danger of THM exposure, EPA regulates the maximum amount of total THMs allowed in tap water. While this can help keep people safe, regulating the total THMs may not necessarily be effective because each type of THM can cause health effects on their own. Furthermore, little is known about the health effects of simultaneous exposure to multiple THMs. EPA has maximum contaminant level goals (MCLGs) for each of the four THMs listed above, but these goals are not enforced by laws or regulations, so they have no power to keep people safe. Because most people get their water from chlorinated municipal water supplies, and because THMs have such serious health effects, more must be done to keep people safe from exposure. This includes more studies to understand the effects of simultaneous exposure to multiple THMs and enforceable standards for individual THMs in drinking water.

Cyanide

Cyanide

Cyanide is a chemical usually found in compounds with other chemicals. Cyanide compounds can be found in some bacteria, fungi, algae, and the seeds of stone fruits. One of the most dangerous cyanide compounds is hydrogen cyanide, a colorless gas that smells like almonds. It is used in industrial processes such as electroplating, metallurgy, metal mining, plastics production, organic chemical production, and photographic developing. Hydrogen cyanide can enter the air surrounding industrial settings where it is used. It can also be produced by combustion engines, tobacco smoke, and the burning of acrylonitrile plastics. (CHEJ has previously written about acrylonitrile here). Because acrylonitrile is used in many consumer plastics, building fires are one of the most common ways people are exposed to hydrogen cyanide.

Breathing hydrogen cyanide for even short amounts of time is incredibly dangerous and can lead to death. When cyanide enters the body it stops cells from being able to produce energy, interfering with many life-sustaining functions of the brain and heart. Early symptoms of cyanide exposure occur within minutes and include headache, dizziness, elevated heart rate, shortness of breath, and vomiting. This can then progress to seizures, decreased heart rate, low blood pressure, coma, heart attack, and death. People who survive exposure can have lifelong neurological impairments. Factory workers who inhaled low levels of hydrogen cyanide over years have reported trouble breathing, chest pain, vomiting, and headaches. Exposure to other cyanide-containing compounds results in the same health effects. Because of the extreme toxicity of cyanide exposure, the use of cyanide-containing compounds and the use of compounds that can produce cyanide when burned should be restricted in order to protect public health.

One Year Anniversary of the Train Derailment in East Palestine, OH

Photo credit: Abigail Bottar / Ideastream Public Media

By Leila Waid.

It’s hard to believe that it has already been one year since the Norfolk Southern train derailed in the small and quiet community of East Palestine, OH. The community members have faced uncertainty and fear of how their health has been impacted by the exposure to toxins, such as vinyl chloride, present at the burn site. Burning vinyl chloride can produce dioxins, a chemical that poses immense danger to human health. Over the year, many residents have spoken out about the health risks they are experiencing, such as increased asthma in their children, skin rashes, bleeding from the ears, and new diagnoses of cancer. Also, residents have pointed out how the train derailment has impacted them financially. One of the residents, Ashley McCollum, talked with ABC News about how she has been displaced from her home for the past year. Unfortunately, Norfolk Southern, who had been paying for her and her family to stay in a hotel, said they would no longer fund her accommodations. Now Ashley and other displaced residents have a hard choice to make – return to the community they believe will make them sick or come up with alternative living arrangements with their own finances.

This harsh abandonment that many residents have experienced feels all the more infuriating when considering how much Norfolk Southern has spent on lobbying. According to Public Citizen, “the company and its subsidiaries spent $2,340,000 lobbying the federal government in 2023 – up 30% from the $1,800,000 it spent the year before.” Interestingly, no new railroad safety legislation was passed by Congress after the Norfolk Southern train derailed. One would imagine that when such a severe accident occurs that threatens the health of thousands of people, the policymakers would immediately work in a bipartisan manner to make sure that such an accident never happens again. Notedly, both the House and the Senate introduced bills to increase railroad safety, but a year later, those bills have not moved forward. House of Representatives member Marcy Kaptur directly connects the lack of action by Congress on the bills to the lobbying being carried out by railroad companies, such as Norfolk Southern.

Without stricter regulation, who knows when and where the next derailment might occur and which American town could be the next East Palestine.

Frustrated by the lack of answers and support, the impacted community in East Palestine created the Unity Council for the East Palestine Train Derailment. One of the most recent actions the Council undertook was a “ceremony of solidarity,” an event held on the first anniversary of the train derailment to raise awareness about the suffering the community is still going through. The Council wanted to showcase to the country that what happened in their community could happen anywhere in the country.

The ceremony was conducted in partnership with We Refuse to Die, an environmental justice campaign utilizing art to communicate the message. Artists and activists have a long history of working together effectively to enact change. By moving people emotionally, artists can tap into the feelings and emotions of individuals that motivate them toward change. In this case, the campaign was focused on showcasing that, just because individuals in East Palestine may have been forgotten about by the railroad industry and politicians, they are still here and will continue to fight until they can rebuild what was stolen from them by the explosion.
