This work investigated the behaviors of seven glucocorticoids, eight androgens, and nine progestogens compared to six estrogens in a municipal sewage treatment plant (STP) in Beijing, China. Among all of the hormones considered, androgens were the dominant steroids detected in all samples (total concentrations up to 10 216±912 ng/L for influents, 171±10 ng/L for effluents, and 647±52 ng/g for dehydrated sludge samples), followed by estrogens (102±8 ng/L, 14±2 ng/L, and 14±1 ng/g), progestogens (57±6 ng/L, 8±2 ng/L, and 13±3 ng/g), and glucocorticoids (42±2 ng/L, 0.7±0.1 ng/L, and 1.2±0.3 ng/g). With the exception of 19-nor-4-androstene-3,17-diol (NAD, 67%), removal rates for androgens were relatively high (98-99%), while those for glucocorticoids, estrogens, and all progestogens except 6α-methylhydroxyprogesterone (MHPT) were 85-99%, 78-99%, and 73-96%, respectively. Glucocorticoids, androgens, and progestogens were mainly removed by degradation as with estrogens, while different behaviors were observed in the aerated grit chamber, anaerobic tank, anoxic tank, and aerobic tank units. Many of the detected glucocorticoids, androgens, and progestogens were eliminated in the anaerobic tank, but estrogens were largely degraded in the aerobic one. Significant increases in the mass of 21α-hydroxyprogesterone (21-HPT) and MHPT in the anaerobic tank and anoxic tank, respectively, were due to deconjugation.
本研究考察了 7 种糖皮质激素、8 种雄激素和 9 种孕激素与中国北京某城市污水处理厂（STP）中的 6 种雌激素的行为。在所考虑的所有激素中，雄激素是所有样品中检测到的主要类固醇（总浓度高达进水 10216±912ng/L，出水 171±10ng/L，脱水污泥样品 647±52ng/g），其次是雌激素（102±8ng/L，14±2ng/L，14±1ng/g）、孕激素（57±6ng/L，8±2ng/L，13±3ng/g）和糖皮质激素（42±2ng/L，0.7±0.1ng/L，1.2±0.3ng/g）。除 19-去甲-4-雄烯-3,17-二醇（NAD，67%）外，雄激素的去除率相对较高（98-99%），而糖皮质激素、雌激素和所有孕激素（除 6α-甲基羟孕酮（MHPT）外）的去除率分别为 85-99%、78-99%和 73-96%。糖皮质激素、雄激素和孕激素与雌激素一样主要通过降解去除，而在曝气砾石室、厌氧池、缺氧池和有氧池中观察到不同的行为。许多检测到的糖皮质激素、雄激素和孕激素在厌氧池中被消除，但雌激素在有氧池中被大量降解。21α-羟孕酮（21-HPT）和 MHPT 在厌氧池和缺氧池中的质量显著增加分别是由于去共轭化。
