Cypermethrin, as a kind of synthetic pyrethroid pesticides which have an increasingly widespread use, has caused a certain amount of residue in the soil. Due to its possibly carcinogenic to human, its residues in the soil should be concerned. And for its complex composition of soil as well as other components of pesticide residues, making the extraction, separation, purification and enrichment of cypermethrin more difficult, the reports about cypermethrin residues in soil was very small. This paper described the fundamental nature of cypermethrin, and preliminarily sum up its existence, behavior and analysis progress in soil.
