天然和合成雌激素可以通过粪便、生物固体或废水进入农业土壤。本研究评价了（i）长期田间应用这种有机土壤添加剂的影响和（ii）14种不同的有机添加剂在一个农业土壤中对（14）C-标记的17 β-雌二醇，雌酮和17 α-炔雌醇的矿化和吸附的短期影响。长期施用有机废弃物导致土壤有机碳（SOC）含量增加，导致雌激素吸附增加。雌激素的矿化增强高达147%或抑制高达50%，这取决于网站和有机废物，但不相关的吸附参数的变化。短期的有机废物的修正案直接增加雌二醇矿化高达70%，在处理过的土壤中相比，在未经处理的控制5%。雌激素的吸附随有机废物的加入量而增加，但有机废物的log K（oc）值为3.1-3.2 L kg（-1），与未处理土壤中的3.5 L kg（-1）相比，显示出较低的雌激素吸附潜力。有机废物改良剂对雌激素行为的影响取决于改良剂的类型和老化。短期有机废物的土壤应用程序导致增强微生物雌激素矿化可能是由于共代谢过程。在具有悠久历史的有机废物修正案的土壤中，雌激素吸附的控制因素是增加的SOC含量。在这些土壤中观察到的雌激素矿化的积极或消极影响还没有得到很好的理解。令人惊讶的是，雌激素吸附到土壤固相的增加，无论是通过短期或长期的有机废物的应用不控制雌激素矿化。
Natural and synthetic estrogens can reach agricultural soils with manures, biosolids, or wastewater. This study evaluates (i) the effects of long-term field application of such organic soil amendments and (ii) the short-term effects of 14 different organic amendments in one agricultural soil on mineralization and sorption of (14)C-labeled 17beta-estradiol, estrone, and 17alpha-ethinylestradiol. Long-term organic waste applications resulted in increasing soil organic carbon (SOC) contents, causing increased estrogen sorption. The mineralization of the estrogens was enhanced by up to 147% or depressed by up to 50%, depending on site and organic waste, but not related to changes in sorption parameters. Short-term organic waste amendments directly increased estradiol mineralization to up to 70% in the treated soil compared with 5% in the untreated control. Estradiol sorption increased with the amount of incorporated organic waste, but the log K(oc) values of 3.1-3.2 L kg(-1) for organic wastes showed a lower sorption potential for estrogens compared with 3.5 L kg(-1) in the untreated soil. The effects of organic waste amendments on estrogen behavior depend on amendment type and aging. Short-term organic waste applications to soil resulted in enhanced microbial estrogen mineralization likely due to cometabolic processes. In soils with a long history of organic waste amendments, the controlling factor for estrogen sorption is an increased SOC content. The observed positive or negative effects on estrogen mineralization in these soils are not well understood. Surprisingly, the increase in estrogen sorption to the soil solid phase either through short-term or long-term organic waste application does not control estrogen mineralization.
