Hazard/Risk Assessment: ecological risk assessment of pesticides on muskrats (ondatra zibethicus) inhabiting an agriculture area in illinois, USA

摘要

A retrospective risk assessment was used to investigate whether pesticide use adversely affected populations of muskrats (Ondatra zibethicus), semi-aquatic mammals inhabiting agriculture drainage ditches in northwestern Illinois. Assessment endpoint benchmark concentrations in water were calculated for muskrats from laboratory rat multiple-generation reproduction no-observed- effect levels. The pesticide root zone models and exposure analysis modeling system simulated pesticide fate and revealed expected environmental concentrations (EECs) of pesticide in receiving water.
