Abstract
Bacterial cultures were incubated with pesticides at concentrations ranging from 1 to 5,000 ppm. The species selected are important in one or more of the following biogeochemical processes: nitrogen fixation, nitrification, denitrification, sulfur oxidation, sulfate reduction, carbon dioxide fixation, and respiratory carbon dioxide evolution. The pesticides used were atrazine, alachlor, carbaryl, parathion, trifluralin, ana 2,4‐D. Bacterial cultures were exposed to commercial formulations of these pesticides and to pesticide samples from active disposal pits.
