WebCypermethrin (CP) is widely used for controlling agricultural and indoor vermin. Previous studies have reported the stereoselective difference of CP in biological activities. However, little is known about their potential mechanisms between metabolic phenotypes and endocrine-disrupting effects. WebCypermethrin is a synthetic pyrethroid used as an insecticide on a large scale. Cypermethrin is highly toxic to fish, bees, and aquatic insects, according to the National Pesticides Telecommunications Network. It is found in many household ants and cockroach killers, including Raid and ant chalk. Cypermethrin 10% emulsifiable concentrate (EC ...
