【摘要】：针对畜禽粪便还田后天然雌激素流失的问题,选择雌酮(E1)、17β-雌二醇(E2β)、17α-雌二醇(E2α)和雌三醇(E3)等天然雌激素,采用HPLC-MS/MS系统建立了仪器分析方法和样品前处理方法;并采用模拟还田的方式,研究了其在还田过程中天然雌激素向水相中的流失特征。结果表明,在模拟还田过程中,雌激素标准品和猪粪中的天然雌激素均可以流失到水相中;与猪粪中的天然雌激素相比,雌激素标准品更易向水相中流失,其流失速度和流失量均高于猪粪。研究结果表明,天然雌激素向水体中的流失受到土壤吸附、猪粪中有机质吸附和降解等因素的影响,而且其流失量与还田量不成正比。
[Abstract]:In order to solve the problem of natural estrogen loss after returning livestock and poultry feces to the field, natural estrogens, such as estradiol E1 (17 尾 -estradiol 17 尾 estradiol 17 伪 estradiol estradiol E 2 伪) and estriol E3) were selected. The instrument analysis method and sample pretreatment method were established by HPLC-MS/MS system. The characteristics of the loss of natural estrogen into water phase in the process of returning to the field were studied by using the method of simulated return. The results showed that in the process of simulated returning to the field. Both the estrogen standard and the natural estrogen in pig manure can be lost to the water phase. Compared with the natural estrogen in pig manure, the standard of estrogen is more likely to be lost in water phase, and its loss rate and loss amount are higher than that in pig dung. The results show that the loss of natural estrogen to water body is adsorbed by soil. The adsorption and degradation of organic matter in pig manure were not proportional to the amount of organic matter returned to the field.

【正文快照】： 环境雌激素能够对动物和人类产生潜在的危害,已被视为新型污染物而成为研究的一大热点[1]。在环境雌激素中,有一类是由人类与其他动物所产生的雌激素,称为天然雌激素。常见的天然雌激素有雌酮(E1)、17β-雌二醇(E2β)、17α-雌二醇(E2α)和雌三醇(E3)。这些雌激素能够同人类和
