Photodegradation of Agricultural Herbicides in Lake Erie Coastal Wetlands

Objectives:  1) Elucidate the role of indirect photolytic degradation of alachlor and atrazine in the water column under natural sunlight conditions. 2) Quantify the effect of photobleaching on NDOM and the role that this process might have on ASOC degradation at the OWC site. 3) Study the propensity for sunlight, NDOM, and nitrate to degrade other ASOCs e.g., atrazine, metribuzin, and metolachlor under synthetic sunlight. 4) Identify important daughter products resulting from the photolysis experiments.  5) Model the degradation kinetics for ASOCs in OWC based upon the parameters derived from the photolysis experiments.
