Pesticide-loss Simulation and Health Risk Assessment during the Flood Season in Watershed Systems

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 water quality and pose risks to human health. During flood season, floodwater could wash off large amount of pesticide residues to rivers and lakes. A pesticide-loss simulation and health-risk assessment (PSHA) system was developed to predict pesticide losses …
