U.S. EPA study reveals PFAS leaches into pesticides stored in fluorinated plastic containers

In its efforts to investigate the presence of PFAS in pesticides since late 2020, the U.S. EPA in their latest study, examined the potential for three different brands of fluorinated high density polyethylene (HDPE) pesticides containers to leach PFAS chemicals into water and methanol over time (both these liquids were used as surrogates for pesticides). It was found that fluorinated containers released PFAS into water and methanol in high quantities upon storage time of over 20 weeks. The U.S. EPA EPA is now asking pesticide makers to analyze their products for PFAS and remove those that are contaminated with PFAS from the market.
