Monoclonal antibodies were obtained against atrazine and its metabolite hydroxyatrazine by immunizing mice with atrazine or hydroxyatrazine protein conjugates. By competitive ELISA, we observed that the antibodies raised against hydroxyatrazine cross-reacted mainly with hydroxypropazine. The antibodies raised against atrazine cross-reacted with propazine, prometone, prometryne, and to a much lower extent with a few other s-triazines and hydroxy-s-triazines. Atrazine could be detected in water samples down to 50 ppt. Average recoveries measured by ELISA from soil samples fortified with atrazine or hydroxyatrazine were comparable to those measured by GLC or HPLC. Soil samples of unknown atrazine content were analyzed by GLC, GC-MS, and by ELISA. The results show that the ELISA immunoassay represents a valuable detection method for trace amounts of atrazine and hydroxyatrazine in soil.
