Isolation and purification of {sup 14}C-atrazine metabolites from field grown sugarcane and sorghum
- Corning Hazleton, Inc., Madison, WI (United States); and others
Sugarcane and sorghum plants were grown in separate field plots and treated with [2,4,6-{sup 14}C]-Atrazine (according to standard agricultural practices and at levels approximating the maximum usage rate) in partial fulfillment of EPA registration requirements. Sugarcane leaves were collected just before the final (fourth) test material application and at final harvest; canes were collected only at final harvest. Atrazine and a total of 20 metabolites of atrazine, accounting for 45.1% of the total radioactive residues, were isolated and characterized from prefourth application sugarcane leaves. Sorghum forage samples were collected 30 days after treatment (30 DAT), and at silage stage; mature fodder and grain were collected at final harvest. Two additional metabolites of atrazine were isolated and characterized from 30 DAT sorghum. Flowcharts describing the extraction and fractionation procedures used for isolation and purification of selected metabolites will be presented. The mass spectra as well as proposed metabolic pathways for these metabolites will be presented in an accompanying abstract.
