1 Concentration and Aquatic Toxicity of RIFA Insecticides and Other Organophosphates in Surface Water March 1999-June 2000 Dave Kim, Johanna Walters, Kean S. Goh August 29, 2000 Irvine, CA

2 Outline Introduction Monitoring Concentration vs toxicity Urban vs. Nurseries Irrigation Runoff vs. Storm Runoff Runoff mitigations Conclusions

32 Conclusions

33 Detections: Irrigation Runoff Single detect: hydramethylnon, pyriproxyfen Nursery: Bifenthrin, Diazinon, Chlorpyrifos, Malathion, Dimethoate <8 ppb Urban: Diazinon, Malathion, Chlorpyrifos <1.5 ppb

34 Detections: Storm Runoff Nursery –bifenthrin, diazinon, malathion, chlorpyrifos, fenoxycarb <6 ppb Urban –diazinon, malathion, chlorpyrifos <1.5 ppb

35 Toxicity: Irrigation Runoff Nursery sites: –18: Bifenthrin, Diazinon, Chlorpyrifos, Malathion –1 unknown –2 non toxic Urban and integrated sites: –27:Diazinon, Malathion, Chlorpyrifos –27 unknown –21 non toxic

36 Toxicity: Storm Runoff Nursery –All 18 samples 100% mortality Bifenthrin, Diazinon, Malathion, Chlorpyrifos Urban –All 18 samples 100% mortality Diazinon, Malathion, Chlorpyrifos Unknown
