Key Points

The research aims to assess the toxic effects of bisphenol A and its analogs in environmental scenarios.
Analyzed mixtures of bisphenol A and five analogs present in European surface waters.
Evaluated concentration-additive effects of these chemicals on biological responses.
Identified which analogs contribute most significantly to cytotoxicity and estrogenic effects.
BPS and BPB were the most common analogs detected in surface waters.
BPB and BPAF were primarily responsible for observed cytotoxicity and estrogenic effects.
Mixtures exhibited additive toxicity at environmental concentration levels.
