Determination and Risk Assessment of Phenolic Endocrine-Disrupting Chemicals in the Rivers of Wuhan

Pollution from phenolic endocrine-disrupting chemicals (PEDCs) poses a significant challenge to aquatic ecosystems. However, information on their occurrence and risks in Wuhan’s two primary rivers is limited. This study analyzed nine PEDCs and water quality parameters, detecting four: 4-n-nonylphenol (22–109 ng/L), octylphenol (25.9–73.7 ng/L), bisphenol A (93.3–258 ng/L), and bisphenol S (0.42–3.30 ng/L). Concentration differences between March and April suggested rainfall may influence. Pearson’s correlation analysis showed water temperature positively correlated with PEDCs, while atmospheric pressure, dissolved oxygen, and oxidation-reduction potential were negatively correlated. Risk assessment indicated low-to-moderate risks for these PEDCs in the rivers.
