“Per- and polyfluoroalkyl substances called PFAS contaminate some pesticides used in mosquito control in Massachusetts and permitted in Vermont. These chemicals never fully break down in the environment, are very soluble in water and bio-accumulate in organisms, including humans. They interfere with hormonal systems (endocrine disruption) at parts per trillion, and are linked to growth, learning and behavioral problems in infants and children, fertility and pregnancy problems, including pre-eclampsia.

Public Employees for Environmental Responsibility identified PFAS compounds at significant levels in insecticides for mosquito control used in Massachusetts and permitted in Vermont. Clarke Company claims the source of PFAS to be the lining of the large plastic barrels in which the pesticides are stored and transported. However, other pesticides contaminated with PFAS are stored in metal drums. So where did the PFAS come from? Scientists in Europe have reviewed the range of PFAS chemicals, their many forms and uses, and indicate that PFAS are used in pesticide products and in pesticide adjuvants as well as in many other household products such as clothing, cookware and cosmetics.

Thanks to the Conservation Law Foundation for working with Public Employees for Environmental Responsibility on this serious issue and urging both the Agency of Natural Resources and the agriculture agency to use their authority and take bold action to guard the health of Vermonters and the land and waters upon which we depend for life.”
