| Abstract: | A 4-yr research program that studied the transformation of alachlor and metolachlor in aquatic systems using field microcosms is presented. The field microcosms provided an accurate simulation of natural ecosystems while also permitting the controlled creation of numerous contamination scenarios and sufficient replication to allow statistical evaluation of the results. Different treatments were assessed including conditions as diverse as anaerobic, eutrophic waters typical of nutrient-rich wetland to aerobic, oligotrophic waters typical of the epilimnion of Canadian glacial lake. Herbicide transformation rate was most strongly affected by water temperature, oxygen conditions, nutrient levels within the system, and the specific herbicide assessed. |
