        There are about 1,900 pesticides registered and 280 pesticides are using only grass protection in Korea. In this study, we evaluated the risk of applicators and passengers exposure by fungicides registered on lawn. Based on this study, we intend to contribute to the establishment of non-agricultural pesticide safety management system. The toxicity of acute oral and dermal exposure was investigated for major 29 fungicides registered for lawn. Restricted entry interval (REI) were set according to the degrees of toxicity were used in USA and Canada. We also assessed the risk of the fungicide applicators and passengers exposure with the current Korea pesticide operator exposure model (Ko-POEM) and US standard operating procedures (SOP) for residential pesticide exposure assessment guideline. The 29 pesticide products consisted of 24 active ingredients, and all 24 were classified as acute toxicity categories III, and REI was set to 12 hours. 12 hours REI can not be accessed until 4 hours after application. However, the certified farmer who wears protective clothing and personal protective equipment can enter for an hour after 4~8 hours and can do works that does not have direct contact with the pesticide sprayed crop after 8~12 hours. As a result of evaluating Ko-POEM using 6 hours 8 hectors spraying a day scenario, 7 items were evaluated as requiring additional high tier test. In the scenario that US SOP for residential pesticide exposure assessment guideline was applied, Hose-end sprayer and 4 hectors spraying a day were used. Results of evaluating, both the applicator and passenger were required additional test on 11 items. Because these results were evaluated using the worst case scenario, it was judged that further detailed study would be necessary.
