These findings highlight the analytical accuracy of the EPA’s testing process and further challenge the previous study’s claims of PFAS contamination in pesticide products.
EPA’s Testing Methodology
Utilizing a newly developed and validated analytical methodology, laboratory analysis was conducted by the EPA to investigate the presence of PFAS in pesticide products containing surfactants.
The EPA’s testing methodology specifically targeted the detection of PFAS in pesticide products formulated with surfactants, which are commonly used as wetting agents to enhance the spreading and adhesion of the active ingredients.
The use of this method allowed the EPA to accurately determine the presence or absence of PFAS in the tested pesticide products.
The EPA’s testing accuracy was compared to a previously published study in the Journal of Hazardous Materials, which reported the presence of PFOS in six out of ten pesticide products tested.
However, the EPA’s evaluation using two different test methods did not detect the presence of PFOS or any additional PFAS in any of the pesticide products.
Notably, the EPA’s level of detection was found to be 2,500 times more sensitive than the limit of detection reported by the study author.
Additionally, the EPA’s method eliminated interference from oils and surfactants present in the pesticide formulations, reducing the likelihood of false positive detections.
These findings highlight the reliability and accuracy of the EPA’s testing methodology in determining the presence of PFAS in pesticide products formulated with surfactants.
