Exposure Characterization Tools for Ecological Risk Assessment of Pesticides in Water

Statistically based soil–climate exposure scenarios for aquatic pesticide fate modeling and exposure assessment in the Pampa Region of Argentina

“…Considering the large rural areas that are treated with pesticides each year in the Pampa region, it is crucial to effectively and accurately evaluate the risk these pesticides pose to water quality and aquatic ecosystem health. In most countries, the regulation and management of pesticide products relies on a methodology known as environmental risk assessment (ERA; Spadotto & Mingoti, 2019). The goal of ERA is to assess the likelihood that adverse ecological effects may occur by comparing the predicted environmental concentrations (PECs) of the pesticide with the concentration below which unacceptable effects will most likely not occur, that is, the predicted no-effect concentrations (PNECs; Schäfer et al, 2019).…”
