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. 17α-estradiol, 17β-estradiol, 17α-dihydroequilin, and estrone were detected in the sampled biosolids and manures at concentrations ranging from 6 to 462 ng/g of dry solids. 17α-estradiol, 17β-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.
许多研究人员报告称，环境中存在天然雌激素激素，其浓度很低，但由于其对生态系统可能产生的不利影响，这种情况引起了越来越多的关注。在这项研究中，对城市生物固体、家禽粪肥（PM）和牛粪肥（CM）以及蘑菇废料（SMC）进行了七种雌激素激素的存在分析。在所采样的生物固体和粪肥中，浓度范围为 6 至 462ng/g 干固体的 17α-雌二醇、17β-雌二醇、17α-二氢马烯雌酮和雌酮被检测到。在 SMC 中也检测到浓度范围为 4 至 28ng/g 干固体的 17α-雌二醇、17β-雌二醇和雌酮。使用去离子水（milli-Q）在实验室中模拟解吸实验，并检查水相中是否存在雌激素激素，以确定它们的解吸潜力。从城市生物固体和 SMC 中分别观察到雌激素激素的解吸率非常低，为 0.4%和 0.2%。报告了不同固体废物来源的总雌激素贡献的估计。动物粪肥（PM 和 CM）在自然环境中对雌激素激素的负荷有很大贡献。
