Permethrin breaks down quickly in the environment. The vapor phase reacts with sunlight to degrade the chemical within a few hours. If released to soil, permethrin is expected to have no mobility. Some will be broken down quickly as a vapor, while the remaining chemical will be absorbed by the soil and biodegraded in less than four weeks. If released into moving water, permethrin is expected to absorb to suspended solids and sediments. Degradation would occur within a few days.
