title: Mutagenicity of dieldrin in the Salmonella-microsome test.
abstract: Dieldrin was assayed in vitro for its mutagenic activity in several strains of S. typhimurium with and without Aroclor 1254 treated mouse liver homogenate (S-9M). The mutagenicity of the insecticide was expressed maximally in all strains in the presence of liver S-9M and less so in three strains without liver microsomes.
