Monsanto PCB Lawsuit [2026 Update]

Polychlorinated biphenyls (PCBs) were extensively produced from the 1920s to the late 1970s, primarily by Monsanto, which was one of the largest industrial chemical manufacturers in the world.

Monsanto’s production of PCBs played a pivotal role in the electrification of America, as these chemicals were widely used for their insulating properties in electrical equipment, contributing significantly to the expansion and efficiency of electrical systems nationwide.

However, due to their environmental and health risks, PCB production was eventually banned under the Toxic Substances Control Act (TSCA), leading to a shift in industrial practices and safety standards.

Despite being banned decades ago, polychlorinated biphenyls (PCBs) persist in various environments, resulting in the filing of numerous lawsuits against manufacturers, primarily Monsanto.

Individuals, schools, and government entities have filed these lawsuits due to exposure and contamination concerns.

Monsanto has faced significant financial repercussions, paying out substantial sums in both verdicts and settlements.

Our law firm is actively investigating cases of potential prolonged exposure to PCBs originating from fluorescent lighting fixtures, caulks, and other construction materials in the St. Louis area.

Our goal is to identify and address these exposures to ensure the safety and wellbeing of those who spend significant time in these potentially contaminated buildings.

If you or a loved one were exposed to PCBs in a St. Louis school and subsequently developed health problems, you may be eligible to file a PCB Lawsuit and seek compensation.

Polychlorinated biphenyls (PCBs) are a group of synthetic organic chemicals that were formerly used in industrial electrical equipment, electrical devices, and even some consumer products.

PCBs were produced in large quantities due to their chemical stability and electrical insulating properties.

Monsanto was a key manufacturer of PCBs, contributing significantly to their widespread use after World War II.

The production of PCBs was eventually banned in 1976 by the Toxic Substances Control Act (TSCA), primarily due to their environmental persistence and potential harmful health effects, despite their initial popularity for electrical insulation and stability.

Where Were PCBs Manufactured?

According to the Agency for Toxic Substances and Disease Registry (ATSDR), more than 1.25 billion pounds of PCBs were produced in the United States between 1929 and 1977.

In the United States, key PCB manufacturing sites included:

1. Sauget, Illinois: Located near St. Louis, Missouri, this site was another significant Monsanto facility involved in the production of PCBs.
2. Anniston, Alabama: One of the most notable locations for PCB production. Monsanto’s facility in Anniston was a major center of PCB manufacturing for several decades.

At plants like those in Anniston, Alabama, and Sauget, Illinois, Monsanto was involved in the production of various PCB congeners alongside other chemicals.

Are There Different Types of PCBs?

A PCB congener refers to one of the multiple chemical forms in which polychlorinated biphenyls (PCBs) exist, distinguished by the number and position of chlorine atoms in their molecular structure.

There are 209 possible congeners, each with unique properties and levels of toxicity.

Different PCB mixtures were used for a range of applications, such as in electrical insulators, coolant fluids, and plasticizers, due to their chemical stability and non-flammability.

Commercial PCB mixtures came in various forms, commonly known by the trade name “Aroclor.”

Each Aroclor product was a different mixture, identifiable by a four-digit number – the first two digits denoting the PCB molecule and the last two indicating the percentage of chlorine by weight.

For example, Aroclor 1254 contained 54% chlorine.

Where Were PCBs Used?

Polychlorinated biphenyls (PCBs) were extensively utilized, particularly from the 1930s to the 1960s.

These substances represent a hidden yet integral component in the fabric of mid-20th-century life and technology.

It wasn’t until years after their implementation, when environmentalists and scientists began uncovering the harmful effects of these chemicals – from contamination of natural ecosystems to direct health risks such as cancer and reproductive issues – that the true cost of rampant PCB usage started to emerge.

Why Were Polychlorinated Biphenyls (PCBs) Used?

Polychlorinated Biphenyls (PCBs) found diverse applications historically due to their unique chemical properties, particularly in industries where flammability was a concern.

The diverse applications of PCBs and similar chemicals in large industries, ranging from electrical equipment to plastics, meant their use was widespread yet often unnoticed by the public.

It wasn’t until instances of catastrophic environmental contamination and emerging health issues became apparent that the veil was lifted on the extensive, yet largely hidden, impact of these chemicals.

The prevalence of Polychlorinated Biphenyls (PCBs) in schools across the United States presents a nationwide concern for student and staff health.

An estimated 13,000 to 26,000 school buildings, constructed or renovated between the 1950s and 1970s when PCBs were widely used, potentially contain these toxic substances.

This issue is not confined to any single region, as PCBs in schools have been a matter of concern from coast to coast.

The Environmental Protection Agency (EPA) has identified schools as critical areas for PCB monitoring, emphasizing the urgency of this widespread issue.

Educational facilities built during the peak years of PCB use incorporated these chemicals in various building materials, including caulking, lighting fixtures, and insulation.

The discovery of PCBs in school environments, such as the significant contamination found at Malibu High School in Southern California, underscores the scale and seriousness of this problem.

This nationwide issue necessitates comprehensive efforts for identification, remediation, and prevention to protect the health and safety of the school-going population.

How are People Exposed to PCBs in Schools?

People are exposed to PCBs in schools primarily through indoor air contaminated by PCB-emitting building materials, as highlighted by Herrick, Stewart, and Allen in their review on PCBs in US schools.

Individuals in schools face chronic exposure risks to PCBs due to the continuous presence of these toxic compounds in building materials like caulks, sealants, and fluorescent light ballasts, which release PCBs into the indoor environment over extended periods.

Research presented at the 8th International PCB Workshop at Woods Hole, MA, emphasized that the PCB concentrations in schools can exceed those found near large PCB-contaminated industrial sites.

Research conducted by the University of Iowa Superfund Research Program stressed that airborne PCBs in schools are a significant health hazard, with levels often surpassing safety thresholds.

The presence of PCBs in paints, dust, and other secondary sources in schools further contributes to the inhalation and dermal exposure risks for children and educators.

These studies and community actions underscore the urgent need for comprehensive testing and remediation strategies to mitigate PCB exposure in educational settings.

Why Were PCBs Used in School Buildings?

PCBs were used in school buildings primarily for their advantageous properties such as durability, chemical stability, and electrical insulation capabilities.

These characteristics made PCBs desirable in a variety of building materials, including caulks, sealants, and certain types of fluorescent lighting fixtures.

Their non-flammability was a key factor, especially in ensuring fire safety in schools.

PCBs also enhanced the longevity and performance of various materials, making them a cost-effective choice for long-term use in public buildings.

In window glazing and masonry materials, PCBs improved flexibility and water resistance, contributing to the structural integrity of school buildings.

However, at the time of their widespread use in construction, the environmental and health risks associated with PCBs were not fully recognized, leading to their extensive application in educational facilities.

How are PCBs Discovered in Schools?

PCBs in schools are often discovered through routine maintenance, renovation projects, or environmental assessments.

When older buildings undergo refurbishment, materials such as caulks, sealants, and lighting fixtures, common in construction prior to the 1980s, may tested for contaminants, including PCBs.

Elevated PCB levels are sometimes identified during these tests, prompting further investigation.

PCBs are sometimes accidentally discovered in schools during renovations or maintenance work when previously undetected contaminated materials are disturbed or tested.

Additionally, air quality assessments in older school buildings can reveal the presence of PCBs, especially if they have been released from deteriorating materials.

In some instances, health concerns or symptoms reported by school occupants lead to environmental testing that uncovers PCB contamination.

These discoveries often necessitate a comprehensive plan for remediation to ensure the safety and health of the school environment.

Lawsuits for PCB Exposures in Schools

Exposed workers and students may be eligible to seek compensation for medical problems and illnesses linked to PCBs.

Lawsuits for PCB exposures in schools often target Monsanto, the primary manufacturer of PCBs, for their role in the distribution and widespread use of these chemicals.

These legal actions typically argue that Monsanto was aware of the health risks associated with PCBs but continued to produce and sell them, leading to significant exposure and health issues in school environments.

Plaintiffs in these cases may seek compensation for health problems and illnesses directly linked to PCB exposure, emphasizing Monsanto’s responsibility in creating a public health hazard.

PCBs, recognized as potential occupational carcinogens, pose a significant risk to public health due to their toxic responses in the human body.

Studies by the Agency for Toxic Substances and Disease Registry (ATSDR) and the Environmental Protection Agency (EPA) have shown that PCBs accumulate in body fat over long periods, leading to an increased risk of various health issues.

The International Agency for Cancer Research (IARC) classifies PCBs as probable human carcinogens, highlighting their potential to cause cancer in humans.

According to the National Toxicology Program, prolonged exposure to PCBs can result in several health complications, including problems related to the immune and reproductive systems.

There is also evidence suggesting that PCB exposure can lead to hearing impairment, adding to the spectrum of its detrimental health impacts.

Medical tests are available to measure PCB levels in the body, which can help in assessing the extent of exposure and associated health risks.

These tests are particularly important for individuals in occupations with a higher likelihood of PCB exposure.

Overall, the persistence and bioaccumulation of PCBs make them a lasting concern in public health and environmental safety.

PCB Air Pollution

Breathing air contaminated with polychlorinated biphenyls is extremely dangerous.

Historically, PCB exposure was predominantly associated with dietary ingestion, but recent studies have highlighted the importance of inhalational exposure, particularly in urban and industrial areas where PCB use was extensive.

“A Review of Polychlorinated Biphenyls (PCBs) Pollution in the Air: Where and How Much Are We Exposed to?” is a 2022 study published in the International Journal of Environmental Research and Public Health that analyzes airborne exposure to PCBs.

The study reveals several key insights:

• Airborne PCBs, especially in urban and industrial environments, are often a result of volatilization from contaminated surfaces or the release during recycling and disposal processes, such as the burning and recycling of e-waste, which is now a major source of environmental PCB pollution.
• The concentration of PCBs in indoor environments is frequently higher than outdoor levels, indicating that indoor sources, such as construction materials containing PCBs, significantly contribute to human exposure through contaminated air.
• PCBs in the air are subject to long-range atmospheric transport, meaning they can be found in regions far from their original source of emission, contributing to global environmental contamination.
• The study emphasizes the need for further research on the health impacts of prolonged exposure to low-concentration PCBs in the air, as well as developing and implementing effective strategies to mitigate this persistent environmental and public health issue.

PCBs present in electrical equipment, schools, and older buildings may be putting public health at risk.
