Abstract
Abstract Residues of chlordane were extracted from a field-contaminated clay loam soil with various solvents under a variety of conditions. Mixtures of hexane-acetone and hexane-2-propanol recovered only 1.93–2.64 ppm total chlordane residues from the air-dried soil as compared to 3.88–4.10 ppm (highest recovery) when 20% water was added to the soil prior to extraction by these solvents. Effects of the amount of water in the soil at the time of extraction, contact time with solvent or water, and extraction methods were also studied.
