Aqueous Film Forming Foam (AFFF) has long been addressed as a lifesaver in firefighting. Its effectiveness in extinguishing fuel fires has made it a key property in airports, military bases, and industrial facilities.
However, the very properties that make AFFF so effective also pose significant health risks to those exposed to it. While cancer has been the most publicized health concern associated with AFFF, it is far from the only one.
This article talks about various health issues linked to AFFF exposure, extending beyond cancer to include thyroid disorders, reproductive problems, and other lesser-known risks.
The Cancer Connection
AFFF contains per- and polyfluoroalkyl substances also known as PFAS. According to the National Institute of Environmental Health Sciences, PFAS is a group of man-made chemicals known for their persistence in the environment.
These ‘forever chemicals’ have been linked to various types of cancer, raising concern among firefighters and communities near AFFF-use sites.
Studies have shown increased rates of kidney, testicular, and prostate cancers in individuals with high PFAS exposure, states Environmental Protection Agency. The cancer risk has led to numerous lawsuits against AFFF manufacturers, with AFFF lawsuit settlement amounts reaching millions for affected individuals.
According to TorHoerman Law, the settlement amount varies depending on the tier category in which the health issue falls. Tier 1 plaintiffs are the ones who have experienced the most severe health issues. Therefore, the settlement payouts range between $2,00,000 and $5,00,000.
Tier 2 includes less severe though significant health problems. Their settlement payout ranges between $1,50,000 and $3,00,000. For less severe and minor health implications, Tier 3 offers settlement payouts between $20,000 and $75,000.
Understanding AFFF’s Primary Health Threat
The cancer risk associated with AFFF exposure comes from its ability to disrupt cellular functions. PFAS can accumulate in the body over time, interfering with normal cell growth and division. This disruption can lead to the formation of tumors and the spread of cancerous cells.
Long-term exposure, even at low levels, may increase cancer risk significantly. Firefighters, in particular, face higher cancer rates due to their frequent contact with AFFF during training and emergency responses.
Research has shown that PFAS can be detected in blood samples years after exposure, highlighting the long-lasting nature of this threat. The persistent nature of these chemicals means that even brief exposures can have long-term health consequences.
This reality has resulted in the increased inspection of AFFF use and a push for alternatives that do not contain PFAS. However, the legacy of AFFF use continues to affect many communities, with contaminated soil and water sources posing ongoing health risks.
Thyroid Disruption
While cancer dominates discussions about AFFF health risks, thyroid disorders represent another significant concern. The thyroid gland plays a crucial role in regulating metabolism, growth, and development.
Science Direct reports that PFAS can interfere with thyroid hormone production and function, leading to a range of health issues. Studies have shown links between PFAS exposure and conditions such as hypothyroidism, hyperthyroidism, and thyroid cancer.
Impact On Hormonal Imbalance
The mechanism by which PFAS affects thyroid function is complex. PFAS can mimic or interfere with natural thyroid hormones, disrupting the delicate balance necessary for proper bodily functions.
This disruption can manifest in various ways, from subtle changes in metabolism to more severe thyroid disorders. Symptoms of thyroid dysfunction may include unexplained weight changes, fatigue, hair loss, and mood swings.
These symptoms can significantly impact the quality of life and maybe mistakenly attributed to other causes. Long-term thyroid disruption can have far-reaching effects on overall health. The thyroid plays a role in heart function, bone health, and cognitive processes.
Disruptions to thyroid function can therefore impact multiple body systems. Children and pregnant women are particularly vulnerable to thyroid disruption, as thyroid hormones are crucial for fetal development and childhood growth.
Reproductive Health Concerns
The impact of AFFF exposure on reproductive health is an area of growing concern. Both male and female reproductive systems can be affected by PFAS, potentially leading to fertility issues, pregnancy complications, and developmental problems in offspring.
These effects highlight the multigenerational nature of PFAS health risks. Research has linked PFAS exposure to decreased fertility rates, hormonal imbalances, and changes in reproductive organ function.
AFFF’s Hidden Threat To Fertility
In men, PFAS exposure has been associated with reduced sperm count and quality, as per NCBI. Studies have also suggested links between PFAS exposure and testicular cancer, further underscoring the reproductive health issues for men.
Women exposed to PFAS may face increased risks of pregnancy-induced hypertension and preeclampsia. These conditions can pose serious health risks to both mother and child. The effects of AFFF exposure on fetal development are particularly concerning.
PFAS can cross the placental barrier, potentially impacting fetal growth and development. Studies have suggested links between prenatal PFAS exposure and low birth weight, developmental delays, and increased risk of certain childhood diseases.
Other Health Risks And The Broader Impact Of AFFF Exposure
Beyond cancer, thyroid disorders, and reproductive issues, AFFF exposure has been linked to a range of other health concerns. These include liver damage, kidney dysfunction, and immunological effects.
The impact on the immune system is particularly noteworthy, as it may increase vulnerability to various diseases and infections. Studies have suggested that PFAS exposure may reduce vaccine effectiveness, reports Nature. This concern has gained new relevance in light of recent global health challenges.
Cardiovascular health is another area of concern. Some research has indicated links between PFAS exposure and increased cholesterol levels, potentially contributing to heart disease risk.
Additionally, there is growing evidence suggesting that PFAS may play a role in the development of autoimmune disorders. These conditions, where the body’s immune system attacks healthy cells, can have wide-ranging and weakening effects on health and quality of life.
The neurological impacts of AFFF exposure are also under investigation. Some studies have suggested potential links between PFAS exposure and neurodevelopmental issues in children, including attention deficit disorders and reduced cognitive function.

Frequently Asked Questions (FAQs)
How can AFFF exposure occur in everyday life?
People can be exposed to AFFF through occupational settings, like firefighting or industrial sites, or environmental contamination when AFFF seeps into groundwater. Drinking water contaminated with PFAS is a major source of exposure for communities near military bases, airports, and firefighting training facilities.
Is there a safe level of exposure to PFAS found in AFFF?
There is currently no universally accepted ‘safe’ level of PFAS exposure, as even low levels can pose long-term health risks. Regulatory agencies have set advisory limits for PFAS in drinking water. However, due to their persistence in the environment and body, even small amounts can contribute to cumulative health risks over time.
How can individuals minimize the health risks of AFFF exposure?
To minimize AFFF exposure, individuals can avoid working with or near the foam. Additionally, wear proper protective gear if handling AFFF, and stay informed about local water contamination issues. Testing water sources and using filtration systems designed to remove PFAS can also help reduce the risk of consuming contaminated water.
It is crucial to prioritize the development and adoption of safer alternatives to AFFF. Efforts to clean up contaminated sites and provide healthcare support to affected individuals must also continue.
By addressing the full spectrum of health risks associated with AFFF exposure, we can work towards protecting generations from its harmful effects. The legacy of AFFF serves as a reminder of the importance of safety evaluations for industrial chemicals and the need to protect public health.
