Use of immunoassays for biomonitoring of herbicide metabolites in urine Original Research Article

Commercially available ground-water immunoassays (RaPID Assay®) are being evaluated to determine their potential value for measuring herbicides or their metabolites in urine. Preliminary investigations of matrix effects and cross-reactivities indicate potential usefulness for the atrazine kit, but not the metolachlor kit, as a urinary biomonitoring tool.
