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.
