In this study the potential estrogenicity and toxicity of BP3 and BP4 as well as chlorinated BP3 product (5-chloro BP3), which could be produced during water chlorination in swimming pools, were studied. Toxic effects of UV filters were studied on bacteria Vibrio fischeri, algae Desmodesmus subspicatus, water fleas Daphnia magna and zebrafish Danio rerio. We found that UV filter BP3 was more toxic than BP4; the highest sensitivity was observed when water fleas Daphnia magna and algae Desmodesmus subspicatus were used as test organisms. BP4 revealed adverse effects on aquatic organisms only at concentrations of some tens milligrams per liter. The acute toxicity of chlorinated product (5-chloro BP3) did not increase significantly in comparison to BP3; increased toxicity was found only in a case of algae. The results of YES assay showed no estrogenic activity of both tested UV filters and chlorinated product. This study of toxicity and estrogenicity of UV filters revealed potential adverse effects of tested UV filters on aquatic organisms. Therefore, due to existing likelihood that UV filters may pass into the aquatic environment, cognition of possible effects of new UV filters on aquatic ecosystems is required before they are commercially available on the market.
