The insecticide has been shown to damage the immune system, nervous system, lungs and cause cancer. Adsorption and gas-liquid chromatography separate toxaphene into at least 175 polychlorinated 10-carbon compounds including Cl 6, Cl 7, Cl 8, Cl 9, and Cl 10 derivatives. ( 2) Toxaphene formulator means a person who produces, prepares or processes a formulated product comprising a mixture of toxaphene and inert materials or other diluents into a product intended for application in any use registered under the Federal Insecticide, Fungicide and Rodenticide Act, as amended ( 7 U.S.C. For In 1976 toxaphene was close behind methyl parathion as the se~ond most heavily used insecticide in the "delta states" of Arkansds, Louisiana, and Mississippi (0.2 million kilograms) and was the sixth most h~avily used insecticide 1n the ~orn belt (0.2 million kilograms) (Schmitt and Winger 1980). Oils and soaps are most effective against scale insects, aphids, whiteflies, and phytophagous mites. The Safe Drinking Water and Toxic Enforcement Act. ). *Toxapheneshould be handled as a CARCINOGEN and a TERATOGEN--WITH EXTREME CAUTION. They act by coating and suffocating small insects or their eggs.

It acts on the neurons, causing an imbalance in sodium and potassium ions, similar to that of the cyclodiene insecticides. is acceptable, provided that you: 1. 2nd September, 1968. Thus OPs and MCs act in the insect's CNS but not at the neuromuscular junction. Decreases in Toxaphene concentrations have been observed throughout the Great Lakes in all media following its ban in the mid-1980s. Recoveries . The E-screen test also revealed that estrogenic chemicals may act cumulatively; when mixed together they induce estrogenic responses at concentrations lower than those required when each compound is administered alone. The use of organochlorine insecticides in the realm of public health is stressed with significant advances made along these lines through the use of DDT against typhus and malaria. It was once widenly used, but it is now banned in most areas due to its toxicity and tendency to bioaccumulate in the environment.
