摘要: Abstract There have been growing concerns over the negative effects of pesticide usage on human health and environmental sustainability. Pesticide residues, if they enter water bodies, will impair quality pose risks to health. During flood season, floodwater could wash off large amount residues rivers lakes. A pesticide-loss simulation health-risk assessment (PSHA) system was developed predict losses evaluate associated during season. case study conducted in Auglaize-Blanchard Watershed Ohio calibrate verify proposed system. The results showed a reasonable prediction accuracy model performance. PSHA then applied estimate assess May 1997 April 1998, especially season from August. show that discharge contributed 90 percent total losses. chronic acute heal...
