Abstract
Degradation and movement of (+)-trans and (+)-cis isomers of permethrin [3-phenoxybenzyl (±)-cis, trans-3-(2, 2-dichlorovinyl)-2, 2-dimethylcyclopropanecarboxylate] in soil were studied under laboratory conditions. When (+)-trans and (+)-cis isomers of permethrin labeled with ^<14>C in the alcohol or acid moiety were applied to two types of soil (Kodaira and Azuchi) at the rate of 1.0 ppm and held at 25℃ in the dark under upland conditions, both isomers were rapidly decomposed with the half-lives of 6 to 12 days. The degradation rate of (+)-trans isomer was slightly faster than that of (+)-cis isomer in both soils. Major degradation products from both isomers were 3-(4′-hydroxyphenoxy) benzyl-3-(2, 2-dichlorovinyl)-2, 2-dimethylcyclopropanecarboxylate, 3-phenoxybenzyl alcohol, 3-phenoxybenzoic acid, 3-(2, 2-dichlorovinyl)-2, 2-dimethylcyclopropanecarboxylic acid, and its hydroxylation derivatives. Although both (+)-trans and (+)-cis-permethrin hardly moved through the soil with water, the degradation products such as 3-phenoxybenzoic acid, 3-(4′-hydroxyphenoxy) benzyl-3-(2, 2-dichlorovinyl)-2, 2-dimethylcyclopropanecarboxylate were slightly eluted with water.
