Environmental context estrogens can disrupt the normal functioning of endocrine systems, and their occurrence in drinking water sources could cause potential health risk. We investigated concentrations four lakes from Taihu Basin, found that BPA EE2 were elevated some sites. However, all environmental below national standards, caused no threat to local population. Rationale The Basin is a critical freshwater ecosystem susceptible contamination various anthropogenic activities. (also known as disrupting chemicals, EDCs) are exogenous substances systems. by EDCs primarily effluents sewage treatment plants livestock poultry farms. In this study, we assessed spatial distribution risks surface basin. Various statistical evaluations employed establish connections between measured concentration heavy elements, physicochemical parameters, identify these contaminants. Methodology Water samples 44 sampling points five Suzhou taken for evaluation estrogens. Gas chromatography–mass spectrometry was used identification estrone (E1), estradiol (E2), ethinyl (EE2) bisphenol A (BPA). Inductively coupled plasma–mass element samples. Results estrogen detected ranging 0.001 209 ng L–1, with highest attributed BPA, whereas E1, E2 comparatively lower. Correlation estrogens, parameters contents revealed positive correlation (P < 0.05) total chromium contents. Consequently, risk entropy value Shanghu Lake exceeded 0.5, indicating potentially high estrogenic activity. Discussion widespread raise urgent concerns, highlighting need frequent monitoring waters throughout year mitigate future. Our results suggest exists Potential methods disruptors have been proposed, which provide actionable plans stakeholders.
