We measured five estrogens in the wastewater samples from the municipal wastewater treatment plants (M-WWTPs), livestock wastewater treatment plants (L-WWTPs), hospital WWTPs (H-WWTPs) and pharmaceutical manufacture WWTPs (P-WWTPs) in Korea. The L-WWTPs showed the highest total concentration (0.195-10.4 μg L(-1)) of estrogens in the influents, followed by the M-WWTPs (0.028-1.15 μg L(-1)), H-WWTPs (0.068-0.130 μg L(-1)) and P-WWTPs (0.015-0.070 μg L(-1)). Like the influents, the L-WWTPs (0.003-0.729 μg L(-1)) and the M-WWTPs (0.001-0.299μgL(-1)) also showed higher total concentration of estrogens in the effluents than the H-WWTPs (0.002-0.021 μg L(-1)) and P-WWTPs (0.011 μg L(-1) in one sample). The L-WWTPs (37.5-543 μg kg(-1), dry weight) showed higher total concentrations in sludge than the M-WWTPs (3.16-444 μg kg(-1), dry weight) like the wastewater. The distribution of estrogens in the WWTPs may be affected by their metabolism in the human body, their transition through biological treatment processes, and their usage for livestock growth. Unlike the concentration results, the daily loads of estrogens from the M-WWTPs were the highest, which is related to the high capacities of WWTPs.
我们在韩国的城市污水处理厂（M-WWTP）、牲畜污水处理厂（L-WWTP）、医院污水处理厂（H-WWTP）和制药厂污水处理厂（P-WWTP）的废水中测量了五种雌激素。L-WWTP 的进水雌激素总浓度（0.195-10.4μg/L）最高，其次是 M-WWTP（0.028-1.15μg/L）、H-WWTP（0.068-0.130μg/L）和 P-WWTP（0.015-0.070μg/L）。与进水相似，L-WWTP（0.003-0.729μg/L）和 M-WWTP（0.001-0.299μgL(-1)）的出水雌激素总浓度也高于 H-WWTP（0.002-0.021μg/L）和 P-WWTP（一个样品中 0.011μg/L）。L-WWTP（37.5-543μg/kg（干重））的污泥中总浓度高于 M-WWTP（3.16-444μg/kg（干重）），与废水相似。WWTP 中雌激素的分布可能受到其在人体中的代谢、通过生物处理过程的转化以及用于牲畜生长的用途的影响。与浓度结果不同，M-WWTP 的雌激素日负荷量最高，这与 WWTP 的高容量有关。
