Development of an enzyme-linked immunosorbent assay for alachlor and its application to the analysis of environmental water samples

(...) Cross-reactivity studies showed that these antibodies were capable of distinguishing alachlor from other structurally similar chloroacetanilide herbicides, including metolachlor, and that they showed little cross-reactivity toward the major soil metabolites of alachlor. (...) The concentration of alachlor in environmental water samples was measured by ELISA, and the results were compared with those obtained by a GC/MS method
