Abstract
Accurate transformation rates of pesticide residues in aquifer material are needed to predict the ultimate effects of pesticide leaching on drinking-water resources. Even slow transformation rates in the groundwater zone can lead to substantial reduction of the concentrations. In this study the transformation of the oxidation products of aldicarb was studied in incubations with water-saturated subsoils collected at four sites in the Netherlands. The transformation rates and products varied with soil type, redox potential, and the concentration of the products. The transformation was very fast in an anaerobic subsoil (half-lives some weeks) but much slower (one to several years) in more aerobic subsoils.
