许多研究人员报告称，环境中存在微量的天然雌激素，并且由于其可能对生态系统产生不利影响而受到越来越多的关注。在这项研究中，分析了城市生物固体、家禽粪便 (PM) 和牛粪 (CM) 以及废蘑菇堆肥 (SMC) 中七种雌激素的存在情况。在采样的生物固体和粪便中检测到 17 α-雌二醇、17 β-雌二醇、17 α-二氢马雌酮和雌酮，浓度范围为 6 至 462 ng/g 干固体。 SMC 中还检测到 17 α-雌二醇、17 β-雌二醇和雌酮，浓度范围为 4 至 28 ng/g 干固体。在实验室中使用去离子水 (milli-Q) 模拟解吸实验，并检查水相中是否存在雌激素以确定其解吸潜力。从城市生物固体和 SMC 中分别观察到 0.4% 和 0.2% 雌激素的解吸率非常低。报告了对不同固体废物来源的雌激素总量贡献的估计。动物粪便（PM 和 CM）在自然环境中产生大量雌激素。
The presence of natural estrogen hormones as trace concentrations in the environment has been reported by many researchers and is of growing concern due to its possible adverse effects on the ecosystem. In this study, municipal biosolids, poultry manure (PM) and cow manure (CM), and spent mushroom compost (SMC) were analyzed for the presence of seven estrogen hormones. 17 alpha-estradiol, 17 beta-estradiol, 17 alpha-dihydroequilin, and estrone were detected in the sampled biosolids and manures at concentrations ranging from 6 to 462 ng/g of dry solids. 17 alpha-estradiol, 17 beta-estradiol, and estrone were also detected in SMC at concentrations ranging from 4 to 28 ng/g of dry solids. Desorption experiments were simulated in the laboratory using deionized water (milli-Q), and the aqueous phase was examined for the presence of estrogen hormones to determine their desorption potential. Very low desorption of 0.4% and 0.2% estrogen hormones was observed from municipal biosolids and SMC, respectively. An estimate of total estrogen contribution from different solid waste sources is reported. Animal manures (PM and CM) contribute to a significant load of estrogen hormones in the natural environment.
