Effects of pH upon the environmental fate of [14C]fenitrothion in an aquatic microcosm.
The environmental fate of [14C]fenitrothion was evaluated in aquatic microcosms held at pH 8.3 or 6.7. No general effect attributable to pH was observed; however, several significant interactions were identified. Of these, the findings that statistically higher amounts of radioactivity were present in water held at pH 6.7 and that significantly less metabolism of the parent compound occurred in the organisms at pH 8.3 were preeminent. These differences seen in metabolism and environmental fate between pH values are relatively minor and do not compromise the safety of the compound.
