An artificial laboratory environment designed to determine microbial interactions with pollutant chemicals is proposed. The system is designed to obtain maximum reproducibility between replicates by dividing a single tank into separate closed chambers. Radiolabeled toxicants are added directly to the core-chambers and monitored for metabolic breakdown. Further information is obtained easily on changes in microbial, physiological indexes induced by the toxicants. Techniques for monitoring effects on the methyl parathion on the microbial population and the fate of this chemical are given.
