Made by the dimerization of hexachlorocyclopentadiene in the presence of aluminum chloride.
In 1976 the EPA ordered a phasing out of the use of mirex for pest control and brought in a ban with exemptions on June 30, 1978.Production History
Activities associated with the disposition of residual pesticides.
Direct use as a pesticide.
Most likely to enter surface waters as a result of soil runoff.
Strongly adsorbed on sediments in aquatic systems.Mode of Entry in Aquatic Environment
Mirex is a GABA (gamma-aminobutyric acid) antagonist. It binds to GABA receptors, reducing the flow of Cl- ions.
Results in convulsions.
Toxicity increases with increasing ambient temperature.Molecular Mode of Toxic Interaction
