ABSTRACT
Release of aldicarb to the environment will occur from its manufacture and use as a systemic insecticide, acaricide, and nematocide for soil use. Aldicarb may volatilize from soil with the rate of its evaporation increasing with the rate of evaporation for water. Release of aldicarb to the environment will occur due to its manufacture and use as a systemic insecticide, acaricide and nematocide for soil use. Few of the studies concerning the degradation and persistence of aldicarb distinguish between chemical and biological degradation. Metabolites detected in aerobic soils included aldicarb sulfoxide and sulfone and their oximes and aldicarb sulfoxide nitrile; under anaerobic conditions no aldicarb sulfone or its hydrolysis products were detected. Based on the estimated Henry’s Law constant, volatilization of aldicarb from water should not be an important fate process. Exposure to aldicarb and aldicarb sulfoxide and sulfone will occur mainly through the ingestion and contaminated drinking water derived from contaminated ground water as well as contaminated food.
