Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that have been used in a variety of products for decades. Known as “forever chemicals,” they do not break down in the environment and can accumulate in human bodies. A recent study from the University of California, Berkeley, has found that cancer-linked PFAS disproportionately affects Asian Americans, raising concerns about heightened health risks in this community.

A Growing Problem

The study, published in the journal Environmental Health Perspectives, analyzed blood samples from over 1,000 people. It found that Asian Americans had an average of 2.3 times higher levels of PFAS than white Americans. While the researchers are not entirely sure why this disparity exists, they speculate that diet, immigration patterns, and occupational exposure could be contributing factors.


Asian Americans are more likely to consume fish and shellfish, which can be contaminated with PFAS. The chemicals often find their way into water bodies and subsequently accumulate in marine life.


Many Asian Americans have immigrated from countries where cancer-linked PFAS exposure is more prevalent, potentially leading to higher baseline levels of these chemicals in their bodies.

Occupational Exposure

Asian Americans are more likely to work in industries such as manufacturing and electronics, where cancer-linked PFAS is common.

The Health Risks of Cancer-Linked PFAS

Risks of cancer-linked PFAS

PFAS have been linked to a myriad of health problems, including cancer, thyroid disease, and decreased fertility. Studies have shown that high levels of PFAS can increase the risk of certain types of cancer by up to 20%. Children are especially vulnerable, as their bodies are still developing, and exposure to cancer-linked PFAS can lead to developmental issues. The study’s findings are particularly alarming for Asian Americans, who appear to be at a higher risk for these health complications.

Social and Policy Implications

The findings could significantly affect healthcare policies targeting Asian American communities. Public health campaigns and interventions could be designed to specifically address the risks and sources of PFAS exposure in these communities. Moreover, the data could be used to advocate for stricter regulations on PFAS usage in industries that disproportionately employ Asian Americans.

What Can Be Done? Individual Actions

  1. Avoid PFAS-Containing Products: Opt for cookware that does not have non-stick coatings and choose carpets and furniture that aren’t marketed as stain-resistant.
  2. Dietary Changes: Limit the consumption of fish and shellfish from waters known to be contaminated with PFAS.
  3. Produce Safety: Wash fruits and vegetables thoroughly, as cancer-linked PFAS can be present on the surface.
  4. Water Safety: Consider using certified water filters to remove PFAS and opt for bottled water if your local water supply is contaminated.

Governmental Actions

PFAS in food packaging

  1. Regulation: Governments can restrict the use of PFAS in consumer products. Some European countries have already banned PFAS in food packaging.
  2. Cleanup: Invest in cleaning up contaminated sites, especially in communities that are disproportionately affected.
  3. Public Awareness: Launch public health campaigns to educate people about the risks of PFAS and how to minimize exposure.
  4. Research: Fund more studies to understand the long-term health implications of PFAS exposure and to develop safer alternatives.

Additional Steps

  1. Cleaning Products: Choose cleaning products that are PFAS-free.
  2. Clothing and Furniture: Avoid using stain-resistant treatments on clothing and furniture.
  3. Water Testing: Regularly test your water supply for cancer-linked PFAS, especially if you live near a manufacturing plant or a military base that uses firefighting foam.

Final Words

The study’s findings highlight the urgent need to address PFAS exposure, particularly among Asian Americans. By taking individual and collective actions, we can mitigate the health risks associated with these harmful chemicals. The issue is not just a concern for Asian Americans but for everyone, as PFAS are pervasive in the environment. However, the disproportionate impact on Asian Americans calls for targeted interventions and policy changes to protect this vulnerable population. By working together, we can make a difference in safeguarding the health of our communities.
