| Abstract/Contents: | Presents a study with the following objectives: "1. Conduct field investigations for pesticide offsite movement such that the data can be used to calibrate regulatory computer model scenarios for turf. 2. To calibrate PRZM/EXAMS scenarios for turf such that the scenarios can be used in tier-2 exposure assessments for turf pesticides. 3. To modify the code of PRZM as necessary based upon the collected data to best represent the turf environment." States that "this year's research focused on collecting current and historical data on specific pesticide degradation products in golf course leachate from lysimeters constructed into golf course greens." Reports that "although the degradation product of chlorothalonil, hydroxychlorothalonil, formed in significant quantities in soil, it should be rapidly and extensively degraded by sunlight in aquatic systems. Photodegradation was predicted to be responsible for 81% of the degradation." This three-year study began in 2000. |

| USGA Summary Points: | Chlorpyrifos was not detected in any sample and chlorothalonil was detected in one sample. The degradation products, trichloropyridinol and hydroxychlorothalonil, were detected in 63% and 87% of the samples, respectively. The highest concentrations were typically associated with periods of greater rainfall. Although the degradation product of chlorothalonil, hydroxychlorothalonil, formed in significant quantities in soil, it should be rapidly and extensively degraded by sunlight in aquatic systems. Photodegradation was predicted to be responsible for 81% of the degradation. |
