A recent study reveals a troubling trend in the use of per-and polyfluoroalkyl substances (PFAS), also known as forever chemicals, in pesticide products. Researchers from the Centre for Biological Diversity, Environmental Working Group, and Public Employees for Environmental Responsibility have discovered that PFAS are not only intentionally added to pesticides but can also leach from fluorinated storage containers, posing a significant threat to human health and the environment.
PFAS compounds like Perfluorooctanoic acid (PFOA) and Perfluorooctane sulfonate (PFOS), known for their extreme toxicity, are increasingly found in common pesticides. These chemicals contaminate waterways, degrade rivers and streams, and are used on widely available agricultural products such as corn, wheat, kale, strawberries, and in insect sprays. The findings, published in the journal Environmental Health Perspectives, highlight the widespread and insidious nature of this contamination.
“Toxic PFAS have no place in our food, water, or homes, posing a serious threat to our health and environment,” stated David Andrews, a senior scientist at the Environmental Working Group. Andrews emphasized the growing concern, noting, “The increasing use of PFAS pesticides will lead to higher levels of PFAS in the environment. Their presence not only endangers agricultural workers and communities but also jeopardizes downstream water sources, where pesticide runoff can contaminate drinking supplies. This situation further illustrates why we must end all non-essential uses of these persistent ‘forever chemicals’.”
The study underscores a critical gap in the current regulatory framework, which does not fully assess the risks posed by PFAS. Researchers are calling for immediate action, including banning the fluorination of plastic containers, identifying all inert ingredients on pesticide labels, and enhancing immunotoxicity testing for PFAS ingredients.
Nathan Donley, the environmental health science director at the Center for Biological Diversity, described the findings as “truly frightening.” He added, “Pesticides are some of the most widely dispersed pollutants in the world. Lacing pesticides with forever chemicals is likely burdening the next generation with more chronic diseases. The Environmental Protection Agency needs to get a grasp on this fast-emerging threat right away.”
As the use of PFAS in pesticides continues to rise, it becomes increasingly urgent to address this issue to protect public health and the environment. The call for stricter regulations and better monitoring is a critical step towards mitigating the impact of these hazardous chemicals.
