The effects of culture filtrates, mixed populations, and common microbial exudates on bacterial transformations of three agricultural and industrial chemicals were investigated. Test chemicals included methyl parathion, diethyl phthalate, and 2,4-dichlorophenoxyacetic acid butoxyethyl ester. The presence of various cultures, filtrates

Daily administration of 2,4-dichlorophenoxyacetic acid-n-butyl ester to rats (2,4-D ester, 150 mg/kg/day SC) initially produced depressions in photocell locomotor activity and increases in landing foot splay. Maximal tolerance developed to these effects following ten days of repeated exposure. By themselves

Fertilized hen eggs were externally treated with 3.1 mg 2,4-dichlorophenoxyacetic acid butyl ester (2,4-D ester) before starting incubation. Liver lipid composition, (14C)2,4-dichlorophenoxyacetic acid (14C-2,4-D) subcellular distribution and covalent binding to proteins and lipids of chicks hatched from these eggs were
