title: [Priority analysis for controlling endocrine disrupting chemicals in municipal wastewater treatment plants of China].
abstract: Ecological risk quotients and estradiol equivalent concentrations of 32 endocrine disrupting chemicals (EDCs) in 4 categories were calculated and analyzed using reported concentrations in secondary effluents from municipal wastewater treatment plants in China, considering both extreme scenario for maximum concentration and moderate scenario for median concentration. These EDCs include industrial chemicals, pesticides, natural estrogens, and pharmaceuticals. In extreme scenario, 12 chemicals of ecological risk and 9 chemicals of estrogenicity were identified. While in moderate scenario, 6 chemicals of ecological risk and 5 chemicals of estrogenicity were identified. After further scoring and ranking, 4 priority EDCs have been suggested for control in municipal wastewater treatment plants in China, including 17a-ethynylestradiol, estrone, nonylphenol, and bisphenol A.
