Environmental fate: Animals:Rapidly oxidised by rat liver microsomal oxygenases via dechlorination, O-demethylation and side-chain oxidation (J. Agric. Food Chem., 1989, 37, 1088).Soil:Major aerobic metabolites are derivatives of oxanilic and sulfonic acids. DT50 in soil c. 20 d (field). Koc 121-309.Plant:In plants, metabolism involves natural product conjugation of the chloroacetyl group, and hydrolysis and sugar conjugation at the ether group. Final metabolites are polar, water-soluble, and non-volatile
