Effects of Animal Manure Storage and Disposal on the Fate and Transport of Manure-Borne Hormones

弗朗西斯凯西北达科他州州立大学法戈奖号：CBET-0730492动物粪便储存和处理对粪便中激素的命运和运输的影响这项研究的长期目标是双重的。首先，澄清集约化畜牧业生产在环境暴露于激素方面的作用，这是评估该行业风险的关键信息。第二，评估商业使用的禽畜废物储存和处置方法对激素的归宿和迁移潜力。需要这些信息来验证可能降低激素风险的处理和处置方法。选择猪养殖是因为它们在所有封闭式动物饲养操作（CAFO;即1000个动物单位）中具有最大的潜力，特别是分娩设施（猪妊娠和分娩的地方），可以产生并向环境提供最有效的雌激素。

First, to clarify the role of intensive livestock production with respect to environmental exposure to hormones, information that is crucial to the assessment of risk from this industry. Secondly, evaluate the fate and transport potential of hormones with respect to commercially-employed livestock waste storage and disposal practices. This information is required to validate handling and disposal practices that can potentially mitigate the risk of hormones.Swine operations were chosen because they have some of the greatest potentials of all confined animal feeding operations (CAFOs; i.e. 1000 animal units), especially farrowing facilities (where pigs gestate and birth), to produce and contribute the most potent estrogens to the environment.
