N-nitrosodimethylamine (NDMA)

Toxic Tuesdays

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

N-nitrosodimethylamine (NDMA)

N-nitrosodimethylamine (NDMA) is a chemical in a class of chemicals called nitrosamines. NMDA is a yellow liquid but readily evaporates at room temperature.

Until the 1970s it was used to make rocket fuel, but was then discontinued because of the resulting environmental contamination. In the United States today, NDMA is only made for scientific research purposes. However, NDMA can be formed as a byproduct when its commonly found precursors come into contact with each other.

These scenarios where NDMA forms as a byproduct occur in industrial settings like water treatment plants, pesticide manufacturing facilities, and pharmaceutical manufacturing facilities. This can result in NDMA entering soil, drinking water, and air.

NDMA can also be formed from precursors found in common consumer products like lotion, cosmetics, beer, cured meat, and smoked meat. When we use these products, we can be exposed to the NDMA in them. Furthermore, foods like cured meat, smoked meat, fish, cheese, and beer are high in compounds called nitrates, which our bodies can convert into NDMA once we eat them. These kinds of consumer products are how most of the population is exposed to NDMA.
 
Exposure to NDMA can cause liver damage in humans. Workers exposed to NDMA in industrial settings had higher risks of liver, blood, bladder, stomach, and prostate cancers. Increased NDMA exposure through food is associated with stomach and colorectal cancers. In studies of laboratory animals, NDMA exposure
caused liver injury and stillbirth as well as liver, lung, kidney, and testicular cancers. Based on all of this evidence, the US Environmental Protection Agency and the International Agency for Research on Cancer both classify NDMA as a probable cancer-causing chemical in humans.

Because NDMA can be found in industrial settings and a wide variety of consumer products, it can be hard to know our exposure risk. This makes it particularly important for the federal government to regulate NDMA precursor chemicals in manufacturing, personal care products, and food preservation in order to keep people safe from the adverse health effects of exposure.

Before recent hurricanes that have reduced towns and cities in the Southeast, there was a trend for Americans most affected by the climate crisis to move to the Midwest.  Now, the question is.. Will there be more?   In a recent article by Stephen Starr, Guardian, https://www.theguardian.com/us-news/2024/sep/22/climate-crisis-americans-move-midwest he noted that the 65,000 person city of Muncie, Indiana may not be the most exciting place in the world,  because it doesn’t have beaches, or year-round warm weather, it is now home to Laura Rivas, a former resident of North Miami Beach, Florida.  

Why?  It was the climate crisis and strengthened hurricanes, flooding and skyrocketing insurance premiums for homeowners or the inability to just obtain homeowner insurance.  Rivas noted, “every hurricane season was worse than the last to the point that insurance companiescouldn’t afford [to operate in Florida] any moreFor her, after receiving a notice that her insurance was being increased to $3,000/month, she knew it was time to go. 

Now she says “My mortgage and homeowner’s insurance are $600 a month, total,” “Five times less than my homeowners’ insurance for a home half the size in Florida.”

Rivas is not alone, many from Puerto Rico fled after 2017.  “It’s probably no coincidence that the majority of the Climate Migrants are coming from Texas, California and Florida, said Evan Hock of MakeMyMove, an Indianapolis-based company that partners with small cities across the country to offer incentives to remote workers to relocate. 

Currently, Hurricane, Helene has shown that there is no escape from the effects of the climate crisis, regardless of location, as noted by the recent weather-related events in the Southeastern states of Florida, Georgia, South Carolina, North Carolina, and Virginia.

Racial Disparities in PFAS Exposure Through Drinking Water

Toxic Tuesdays

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

Racial Disparities in PFAS Exposure Through Drinking Water

Per- and polyfluoroalkyl substances (PFAS) are a class of chemicals used in many consumer products and industrial processes since the 1950s. Because there isn’t federal regulation of their use or disposal, PFAS are commonly released into the environment. When PFAS are released, people can be exposed to them through air, dust, food, and water, so PFAS exposure is common in the United States. Biomonitoring studies have found that certain species of PFAS are present in the blood of almost all US residents.

Many species of PFAS are known to have adverse health effects on humans including increased cholesterol levels, changes in liver enzymes, decreased vaccine response in children, increased risk of high blood pressure in pregnant women, and decreased birth weight. Epidemiologic studies also show a link between exposure to certain species of PFAS and increased rates of kidney, prostate, and testicular cancer.

While there many ways to be exposed to PFAS, one of the most common is through contaminated drinking water. It is estimated that 200 million people in the US receive PFAS-contaminated drinking water. In 2018 New Jersey became the first state to adopt enforceable standards for PFAS in drinking water. It established maximum contaminant levels (MCLs) – which are the highest amount of a contaminant allowed in drinking water – for three of the most common species of PFAS: perfluorooctane sulfonate (PFOS), perfluorooctanoic acid (PFOA), and perfluorononanoic acid (PFNA). In April 2024, the US Environmental Protection Agency (EPA) announced the first federal drinking water standards for six PFAS including PFOS, PFOA, and PFNA.

In establishing MCLs for PFAS, New Jersey mandated statewide testing of all Community Water Systems (CWSs, the government-regulated water utilities) in the state. These CWSs tested by New Jersey serve 77% of the statewide population. A recent study used 2019-2021 CWS testing data along with Census data to evaluate if there are demographic differences in PFAS contamination of New Jersey residents’ drinking water. The study calculated quarterly averages for 491 CWs over this time period. It found that PFAS were detected above New Jersey’s MCL in 14% of CWSs, which serve 23% of the population. 

The study also mapped demographic information from census block groups – which are portions of census tracts and generally contain 600-3,000 people – onto the boundaries of each CWS. This created a map where the demographic makeup and quarterly average PFAS concentrations for each CWS were known. 27% of the non-Hispanic white population were served by CWSs with PFAS above New Jersey’s MCL. In contrast, 52% of the Asian population, 38% of the Hispanic population, and 34% of the Black population were served by CWSs with PFAS above New Jersey’s MCL.

These results demonstrate that not only is PFAS contamination prevalent in drinking water in New Jersey, but that there are racial disparities in PFAS contamination by CWS service area. Compared to white populations, Hispanic, Asian, and Black populations are more likely to receive drinking water that has PFAS contamination above the state’s safe threshold. These racial disparities in drinking water quality mirror racial disparities in the US more generally. Historical and ongoing housing discrimination leads to communities of color being excluded from living in certain areas. Throughout the country, pollution-emitting facilities are disproportionately located in nonwhite neighborhoods, driving health and environmental problems that disproportionately affect people of color. Industrial and military facilities that use PFAS and are located in nonwhite neighborhoods may contaminate the water supplying nearby CWSs, which could explain the racial disparities in drinking water discovered in this study.

It is important to note that EPA’s new MCLs for PFAS species are below New Jersey’s MCLs. Complying with these federal standards could reduce racial disparities in PFAS water contamination in New Jersey, but only with robust federal enforcement. People in New Jersey and across the US – especially people of color who have been disproportionately harmed – need enforceable standards and effective enforcement of those standards in order to be safe from PFAS in their drinking water.

Climate Change and the Impact on Maternal Health

By Leila Waid.

Climate change is already having an enormous impact on our world. All individuals are at risk from the debilitating effects of climate change due to an increase in events such as heat waves, flooding, wildfires, and other natural disasters. However, some individuals are more at risk than others and face higher disparities, such as pregnant women and neonates. 

One of the most significant consequences of climate change already being felt are the overbearing heat waves that roll in summer after summer. And every year, it just seems to get hotter and hotter. In fact, not only does it “seem” to, but it actually does get warmer. In fact, “summer 2024…was the warmest summer on record for the Northern Hemisphere, beating the previous record set in 2023 by .66 degrees Celsius, or 1.19 degrees Fahrenheit.” What will next year bring? What about the next five or ten years? And how will the most vulnerable among us be able to adapt to these changes?

Pregnant individuals and their fetuses are extremely vulnerable to health exhaustion and heat stroke. For example, a study found that exposure to high temperatures during pregnancy was associated with an increased risk of childhood lymphoblastic leukemia. Most alarmingly, the study found that the correlation was strongest during the first trimester – specifically at eight weeks of gestation. At eight weeks of pregnancy many individuals may not even know they are pregnant. Thus, this could potentially lead to higher levels of heat exposure since the pregnant person may not realize that they need to take preventive measures, such as staying hydrated and keeping out of direct sun.

Another study found that exposure to high temperatures during pregnancy was associated with an increased risk of the infant being born low-weight and pre-term. The study also found an association between high-temperature exposure and stillbirth. The risk was most pronounced for women in lower socioeconomic levels, with higher income providing a protective factor against the health risks.

And it is not only the fetus that suffers from exposure to high temperatures, but the pregnant person also faces increased health risks. A study found that heat exposure was associated with a 27% increased risk of severe maternal morbidity (SMM). The study defines SMM as a “near-miss for maternal mortality, referring to severe and unexpected conditions during labor and delivery.” Notedly, the study focused on both short-term and long-term exposure to heat and found that both exposure types were associated with an increase in SMM. These findings suggest that even one exposure to a heat wave could impact a pregnant individual’s health status.

Unfortunately, heat waves are not the only pathway through which climate change harms pregnant women health and well-being. For example, researchers are analyzing the effect that flooding has on pregnancy outcomes. A particular concern, especially in low-and-middle-income countries (LMIC), is how flooding can impede individuals’ ability to access much-needed healthcare services, especially in situations where walking to the healthcare center is the only option – such as in this research study conducted in Zambia. And even if transportation access is usually reliable, resources can still become scarce in emergency situations, with ambulances and medical workers being overwhelmed during flooding events. For example, a study found that pregnant women exposed to extreme floods in South Carolina had increased risk of SMM.

However, even putting aside the practical ways, such as transportation, by which flooding can complicate access to prenatal, labor, and post-natal care needs, there is also the emotional toll that the experience places on the pregnant individual. One study focused on comparing mental health outcomes for women who were pregnant during Hurricane Katrina and women who were not. The researchers found that pregnant people had much higher rates of Post-Traumatic Stress Disorder (PTSD) and depression compared to their non-pregnant counterparts.

As evident, the impact of climate change on pregnant people is multidimensional and compounding. But we are not hopeless or helpless in fighting to address this issue. Advocating for climate change policies is the best way to help address the health inequalities pregnant women face and guarantee they and their children can be healthy and thrive. We must ensure that the next generation is born into a greener, more beautiful world.

A Compensation Program for First Responders, Cleanup Workers and Others Impacted by the Toxic Cloud Released by the Collapse of the World Trade Center Towers in New York

September 11th
Photo from https://www.loc.gov/pictures/item/2002717279/

By Stephen Lester.

Today marks the 23rd anniversary of the horrific attacks on the United States that resulted in nearly 3,000 deaths and 6,000 injuries when al-Qaida hijackers crashed four jetliners into the twin towers in New York City, the Pentagon and a field in southwest Pennsylvania on Sept. 11, 2001. 

The legacy of the events from that day continues for the first responders, volunteers and nearby residents in New York City who were exposed to the toxic cloud that resulted when the two World Trade Center buildings collapsed. These people were exposed to a mixture of particulate matter and chemical agents, some of which are known human carcinogens or linked to various respiratory illnesses.

To help survivors and first responders involved in the attack, the September 11th Victim Compensation Fund (VCF) was established by the U.S. Department of Justice on Sept. 22, 2001 to provide compensation for individuals who suffered physical injuries or took part in the cleanup efforts in the aftermath of the attacks. The James Zadroga 9/11 Health and Compensation Act of 2010 would later reactivate the VCF and lead to the creation of the CDC’s World Trade Center Health Program (WTCHP) to provide additional medical benefits to victims.

The WTCHP offers medical screening, monitoring, and treatment to 9/11 first responders and survivors with presumptive WTC-related health conditions. The program also covers medically associated conditions that resulted from treatment or progression of WTC-related health conditions. To establish these associated illnesses, the WTCHP’s established a Scientific/ Technical Advisory Committee (STAC) of medical and environmental health specialists who conduct extensive scientific literature reviews to identify health conditions that may be related to the particulates and chemicals present in the toxic cloud. This committee also makes recommendations regarding additions to the program’s eligibility criteria and WTC-Related Health Conditions List. This fund is not only for those who were first responders, but to also for nearby residents and others who were impacted by chemicals in the toxic cloud. 

The main criteria for people to receive assistance through the Victim Compensation Fund are:

  1. Proof certified by a program-affiliated physician of 9/11-related physical injury or condition listed as WTCHP’s eligible presumptive illnesses. Certification indicates that an applicant’s condition is among one of the WTCHP’s presumptive conditions and their exposure to the 9/11 attacks likely caused, aggravated or contributed to that condition.
  2. Proof of presence at one of the attack sites or along debris removal routes during Sept. 11, 2001 through May 30, 2002.
  3. Proof that they belong to an eligible group (first responders and/or survivors).

Importantly, people do not have to show proof that their presence at an attack site or debris removal site caused their illness or injury in order to receive assistance.

The September 11th Victim Compensation Fund (VCF) has been extended to 2090 and plans to continue to secure funding. Officials at the Department of Justice, which runs the program warned in Time magazine in 2019 “that people exposed to the toxins released during the Sept, 11th attacks and their aftermath may not even be experiencing the full health effects yet. For instance, the world Trade Center was known to contain asbestos which causes mesothelioma, a deadly disease that can take decades to appear.” This stark observation has been borne out by researchers at the Mount Sinai World Trade Center Health Program Clinical Center of Excellence at the Mount Sinai School of Medicine who reported 

a 219% increased risk of thyroid cancer, a 41% higher risk of leukemia and a 25% increased risk of prostate cancer for workers involved in the response and cleanup. This study covered 12 years post exposure. Long-term effects are likely to continue well into the future. 

To date, the more than $12.9 billion in financial compensation was been given out through these programs. If you know anyone who was in New York on that day who feels they were exposed to the toxic cloud that engulfed lower Manhattan when the buildings collapsed, ask them to reach out to the September 11th Victim Compensation Fund (VCF). There’s may be an opportunity to be evaluated by medical experts familiar with chemical exposures.

The Government’s Approach to Evaluating Health Problems in Communities

Toxic Tuesdays

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

The Government’s Approach to Evaluating Health Problems in Communities

Communities exposed to toxic chemicals from industrial pollution struggle to get answers about whether the pollution has caused the health problems in their community. Groups organize to pressure the government to stop the pollution and to clean up the contamination. But these agencies have few answers and often little is done. Frequently states ask the Agency for Toxic Substances and Disease Registry (ATSDR) to investigate the health problems reported in a community. Initially, ATSDR is welcomed because people think that someone is finally going to provide some answers about the health problems in the community.

The Agency for Toxic Substances and Disease Registry (ATSDR) was created in 1980 to address health problems at Superfund sites. Their mission is to protect communities from harmful health effects related to exposure to both natural and man-made hazardous substances. ATSDR is the right agency to evaluate health complaints in a community and they have been doing so for more than 30 years. And for most of this time, the agency has repeatedly failed to answer the questions people raise about whether there’s a link between health problems and the pollution in the community. CHEJ has written much about ATSDR over the years1.

Last month an investigative report by the news service Reuters took an extensive look at ATSDR’s work. The report, “How a US health agency became a shield for polluters,” analyzed 428 reports issued by the agency from 2012 to 2023. Those reports contained 1,582 conclusions about potential harms at contaminated sites. Reuters found that in 68% of its findings, the ATSDR declared communities safe from hazards or did not make any determination at all. That record of finding little harm “strains credulity,” said one former EPA official quoted in the report.

Other key findings included:

  • The agency’s frequent declarations of no harm often are rooted in faulty research. At least 38% of the time, agency reports show, its researchers relied on old or flawed data.
  • At least 20 times from 1996 to 2017 the agency declared that a potential hazard posed no health risk – only to be refuted later by other government agencies or the ATSDR itself. The errors impact communities in AlabamaCaliforniaMissouriNew York and North Carolina.
  • Despite decades of criticism, the agency continues to publish research that relies upon practices its own review board called “virtually useless.”
  • The agency’s common practice of publishing inconclusive reports feeds a long-standing corporate strategy of using scientific uncertainty to deflect regulation and liability for polluted sites.

How is it possible that ATSDR has operated like this for so long? Some answers come from a symposium hosted by ATSDR in 2012 on the Future of Science at ATSDR2:

“In conducting its core work of assessing health risks at contaminated sites, ATSDR has faced a large workload with limited authority and resources to collect needed data. Moreover, concerned communities have voiced legitimate public health questions that ATSDR could not answer fully with existing scientific tools and knowledge.

This meeting documented many scientific limitations and challenges facing the agency. ATSDR’s Board of Scientific Counselors hired a consultant who reviewed the agency’s scientific work and came to these conclusions and observations:

  • An alarming gap persists between public expectations and the limited tools available to scientists to assess the public health effects of hazardous waste sites and uncontrolled releases. This gap is due, in part, to the inherently complex and uncertain relationship between diseases and chemicals emanating from hazardous waste sites and uncontrolled releases. Many substances commonly found at hazardous waste sites and in uncontrolled releases may also emanate from other sources and are routinely detected at low levels in air, water, food, consumer products, or other media. No field-based methods are readily available for measuring the portion of a particular ambient exposure or internal dose that is attributable to a specific hazardous waste site or uncontrolled release.
  • In the absence of scientific methods for assessing the unique contribution of releases from hazardous waste sites and uncontrolled exposures to disease, ATSDR scientists rely upon surrogate methods and designs (e.g., comparing exposures to disease rates in communities with a hazardous waste site with “background” levels). Such approaches, although squarely within the mainstream of environmental science, typically are not robust enough to detect adverse health effects caused by site-specific exposures to toxic chemicals.
  • EPA and ATSDR scientists calculate theoretical risk estimates based on a host of assumptions about contaminant concentrations, exposure duration, characteristics of the exposed population, acute and long-term health risks and other factors.
  • ATSDR relies predominately on environmental data collected by other agencies (primarily EPA and state agencies) for its health assessments. Such data often are not adequate or appropriate for addressing specific questions about current exposures and pathways.

Without good tools to evaluate the impact of chemical exposures on people, ATSDR, EPA and other government agencies will continue to struggle to address pollution and contamination in communities. It’s time to recognize and to acknowledge that scientists know very little about how exposures to toxic chemicals, especially to low level mixtures, lead to adverse health outcomes.

Instead of trying to link cause and effect (the agencies default approach), which is virtually impossible to achieve because of the inherently complex and uncertain relationship between disease and chemical exposure and the limited tools to evaluate health effects, isn’t it time to consider whether there’s enough information and evidence about exposure and adverse health problems in a community to take action to protect people exposed to toxic chemicals?

Until there is a change in how government approaches health problems in a community, you can expect ATSDR to continue to investigate health problems in communities using the same approach that’s reflected in the Reuters article.

“A National Sacrifice Zone” Radioactive Waste Problems In St. Louis

Photo Credit: SCFiasco/Flickr

By Sharon Franklin.

Reporters have found an increased cancer risk for some people who, as children, played in a creek contaminated with uranium waste.  This has caused a grade school to close amid radiation concerns. A landfill operator is spending millions to keep underground smoldering from reaching nuclear waste illegally dumped in the 1970s, according to documents reviewed by The Associated Press.  Both the federal government and companies responsible for nuclear bomb production and atomic waste storage sites in the St. Louis. Missouri area in the mid-20th century were aware of health effects that haunt this region.

Recent articles published by the Associated Press AP “How America’s push for the atomic bomb spawned enduring radioactive waste problems in St. Louis” and  Environmental Health News “A Forgotten Chapter: Downwinders Fight For Recognition and Justice”  highlights the risks, about spills, improperly stored contaminants and other problems that have been often ignored by both the federal government and the polluting companies. 

The government cleanup is complete, but the site is considered permanently damaged and will require oversight into perpetuity. Rather than remove the waste, the government built a 75-foot-tall mound, covered in rock, to serve as a permanent disposal cell for much of the waste. The government said the site is safe, but local residents remain worried, because they live near contamination sites and the uncertainty, because many grew up in the area and weren’t told about the risks for decades.  People in the St. Louis area remain concerned that more illnesses are caused by the contamination and some are pushing for legislation to compensate those who are sick.

Twisting the Language of Civil Rights Law, and Entrenching Environmental Injustice

By Charlie Reeves

As pollution seeps into low-income and minority communities at disproportionate rates, populations are continuously left unprotected. On Wednesday, August 21, 2024, a U.S. District Court in Louisiana ruled that the Environmental Protection Agency did not have the authority to investigate and determine if pollution-creating factories disproportionately impacted predominantly-minority areas. 

Title VI of the 1964 Civil Rights Act is intended to ensure that federal funds are never used to discriminate against anyone on the basis of race or ethnicity. The EPA, investigating and attempting to shut down chemical plants and other sources of industrial pollution that were affecting marginalized communities, was accused of going beyond the true scope of Title VI enforcement. The Louisiana court ruled that, due to the impacts of pollutants unintentionally affecting low-income and minority areas, there was no legal violation. 

The decision in Louisiana only applies to the state, but it represents a far greater concern within the push for environmental justice. The burden of proof is endlessly being placed onto the shoulders of the most vulnerable—the at-risk communities themselves—although it has been proven time and time again that racial minorities suffer disproportionately from the effects of fossil fuel pollution. The Environmental Protection Agency was originally sued by the state of Louisiana for no more than an investigation into the potential violation of civil rights law. Now the agency is barred from asking questions that could save lives and expose blatantly racist corporate decision-making. 

In Louisiana, Black communities have been repeatedly abandoned when it comes to environmental policy and injustices. In “Cancer Alley”, a stretch of predominantly Black communities surrounded by petrochemical plants with rampant toxic emissions, the cancer rate is seven times the national average. The EPA and the state of Louisiana have failed to help minority communities like this, sometimes known as “sacrifice zones”.

Sacrifice zones are clusters of industrial facilities with adjacent communities nearby, and they are devastating microcosms of environmental injustice, government neglect, and tricky legal loopholes used by greedy corporations. 

After the recent ruling, though, a more malicious handling of low-income and minority communities’ concerns has been revealed. By blocking the EPA from attempting to reveal discriminatory actions, Louisiana has set a concerning precedent. With the EPA’s regulatory powers being constrained into near-oblivion, and with the courts in many areas newly emboldened to dismiss concerns that lie at the intersection of civil rights law and environmental law, a framework has been established where injustice cannot even be properly identified as such.

Acrylamide

Toxic Tuesdays

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

Acrylamide

Acrylamide is a clear, odorless chemical. It has many industrial uses, including treating waste water
discharge from water treatment plants. It is also used in the production of industrial products like dyes,
paper pulp, grout, plastics, and construction materials. Many consumer products are also produced
using acrylamide, such as contact lenses, cosmetics, fabrics, textiles, and sugar. When acrylamide enters
the environment, people are most likely to be exposed to it by drinking contaminated water. Acrylamide
can enter drinking water through the water treatment process or through improper disposal from
industrial facilities that use it to manufacture products.

Exposure to acrylamide can have serious effects on the brain, causing numbness in the hands and feet,
disorientation, loss of balance, and muscle weakness. Skin contact with acrylamide can cause irritation,
dermatitis, and nerve damage. Studies in laboratory animals have found that acrylamide exposure can
also cause defects in the male reproductive system, but it is unknown if it has the same effects in
humans. Based on studies in laboratory animals, the US Environmental Protection Agency classifies
acrylamide as probably causing cancer in humans. The International Agency for Research on Cancer
classifies it as likely causing cancer in humans.

In 2002, acrylamide was discovered to form when foods rich in starch are grilled, baked, or fried above
250°F. This includes foods like potato chips, French fries, and breakfast cereals. The resulting acrylamide
can be found in the dark brown or burnt areas of these foods. Since this discovery, many regulatory and
public health agencies across the world have called for more research into whether this dietary
exposure to acrylamide increases the risk for cancer. The American Cancer Society says that based on
existing studies in humans, dietary acrylamide exposure is unlikely to be linked to increased cancer risk.
However, the ACS says that more research on this topic is needed to fully know if dietary acrylamide
poses a cancer risk. This research will be crucial in understanding how widespread cancerous acrylamide
exposure may be.

Protecting Children’s Health

By Gregory Kolen II.

As the world faces increasing environmental challenges, from climate change to pollution, the most vulnerable among us often bear the brunt of these impacts—our children. Environmental justice is not just about addressing the broad issues of pollution and climate change; it’s about ensuring that every child, regardless of where they live or the color of their skin, has the right to grow up in a healthy environment. Protecting children’s health through environmental justice is a moral imperative that requires urgent attention and action.

Children are particularly vulnerable to environmental hazards due to their developing bodies and behaviors. They breathe more air, drink more water, and eat more food per unit of body weight than adults, making them more susceptible to the harmful effects of pollution. Additionally, children’s natural curiosity often leads them to explore their environments, sometimes exposing them to toxic substances in soil, water, and air.

Pollution, from industrial emissions to pesticides in agricultural areas, disproportionately affects low-income communities and communities of color. These communities often live near highways, factories, and waste disposal sites, where the air is thick with pollutants that contribute to respiratory diseases, developmental delays, and other health problems in children.

The environmental injustices faced by children in marginalized communities are stark. For example, children in urban areas with high levels of traffic pollution are at a greater risk of developing asthma. According to the American Lung Association, children living in low-income neighborhoods are twice as likely to suffer from asthma as those in wealthier areas. This disparity is not just a health issue but a social justice one, as it reflects broader systemic inequalities.

In rural areas, the use of pesticides and poor access to clean water pose significant health risks. Children in agricultural communities are often exposed to harmful chemicals used in farming, leading to higher rates of neurodevelopmental issues and cancer. These children, often from migrant worker families, are caught in a cycle of poverty and environmental neglect.

Addressing these injustices requires strong environmental policies and advocacy at all levels of government. Environmental justice must be at the forefront of policy-making, ensuring that regulations protect the most vulnerable populations. This includes stricter controls on industrial pollution, improved standards for clean water, and the reduction of pesticide use near schools and residential areas.

Moreover, community-driven solutions are essential. Empowering communities to have a voice in the decisions that affect their environment is crucial for creating sustainable change. Grassroots organizations, often led by parents and local leaders, play a vital role in advocating for safer environments for their children. These groups have been instrumental in pushing for legislation that addresses environmental hazards in schools, playgrounds, and homes.

Protecting children’s health through environmental justice is not just about reducing pollution or cleaning up toxic sites. It’s about ensuring that every child, regardless of their socioeconomic background, has the opportunity to live in an environment that nurtures their growth and development. It’s about breaking the cycle of poverty and health disparities that plague marginalized communities.

We must hold industries accountable for their environmental impacts and demand that our leaders prioritize the health of our children in their policy decisions. Every child deserves to grow up in a safe, clean, and healthy environment. The fight for environmental justice is a fight for our future—one where all children have the chance to thrive.

Together, through advocacy, policy change, and community action, we can protect our children’s health and build a more just and equitable world.
