This study assessed the acute and chronic risk of pesticides, singly and as mixtures, for fish
using comprehensive chemical data of four monitoring studies conducted in small-and …

This paper presents the ecotoxicological assessment and environmental risk evaluation of
complex pesticide mixtures occurring in freshwater ecosystems in southern Sweden. The …

The risks associated with pesticides in small streams remain poorly characterized. The
challenges reside in understanding the complexities of (1) the highly dynamic concentration …

Surrogate species are used in standard toxicity tests for the environmental risk assessment
of chemicals. Test results are then extrapolated to the situation in the field, which is often …

Given the multitude of pesticides used in agriculture, adjacent streams are typically exposed
to pesticide mixtures. Previous studies analysed the ecological risks of a few pesticide …

Background Due to their high biodiversity, small water bodies play an important role for
freshwater ecosystems. Nonetheless, systematic pesticide monitoring in small creeks with a …
