Review of the environmental fate and effects of two UV filter substances

Sunscreens containing UV filter substances, such as octocrylene (OCR) and butyl-methoxydibenzoylmethane (BMDBM), have been increasingly used to protect human skin against UV radiation. Both substances have been detected in monitoring studies in the freshwater and marine environment, and there has been concern about potential effects on aquatic organisms. In the present work, the environmental fate […]

Publication: Evidence for specific receptor-mediated toxicity of pharmaceuticals in aquatic organisms

The toxicity of 17 active pharmaceutical ingredients (APIs) was investigated using standardized acute and chronic tests with Daphnia magna and 2 algae species. Chronic toxicity was generally greater for Daphnia than for algae. Compilation of additional data resulted in 100 APIs for which the acute-to-chronic ratio (ACR) was determined for Daphnia. The frequency of high…

New project started: ARISTO

As acknowledged by the European Food Safety Authority (EFSA) soil microorganisms play a key role in ecosystem functioning and there is a lack of appropriate methods to assess impacts on them. ARISTO, the European Industry-Academia Network for Revising and Advancing the Assessment of the Soil Microbial Toxicity of Pesticides, started in 2021 and addresses this […]
