Chronic exposure to allethrins alters the plasma biochemical profile of humans and may have adverse health effects. [2] Bioallethrin has been shown to cause oxidative damage, cellular toxicity and necrosis of human lymphocytes studied in vitro. [3] It is highly toxic to fish and aquatic invertebrates.
Cyfluthrin is a pyrethroid insecticide and common household pesticide. It is a complex organic compound and the commercial product is sold as a mixture of isomers.Like most pyrethroids (MoA 3a), [1] it is highly toxic to fish and invertebrates, but it is far less toxic to humans. [2]
