In 2019 and 2020, EPA published the following documents: A white paper reevaluating the FQPA safety factor for pyrethroids. xref Water at pH 7 is neutral, meaning there are an equal number of hydrogen and hydroxyl ions in the solution. Permethrin is more toxic when formulated with corn oil, dimethyl sulfoxide, and propylene glycol than when in an aqueous suspension (perhaps because of greater solubility of permethrin in organic solvents than in water) . It would also not be expected to persist in soil or water systems. Pyrethroids vary in susceptibility to sunlight. 0000001785 00000 n Pyrethroids and pyrethrins are primarily released to the air because of their use as insecticides. %PDF-1.4 %���� From this it was concluded that permethrin could persist in sediments(4).

Environmental Fate: Permethrin and resmethrin have very low solubility in water (54, 55), and bind tightly to soil and sediment particles, rarely leaching into groundwater. Permethrin is more persistent in sediment, as well as in soil where it can have a half-life of 5 to 42 days. Sigma-Aldrich offers a number of Permethrin products.
