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编号：CBET-0730492动物粪便储存和处置对粪便携带的荷尔蒙的命运和运输的影响这项拟议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荷尔蒙暴露方面的作用，这些信息对于评估该行业的风险至关重要。其次，评估荷尔蒙在商业使用的禽畜废物储存和处置实践中的命运和运输潜力。选择猪饲养场是因为它们在所有密闭动物饲养作业(CAFO；即1000个动物单位)中具有最大的潜力，尤其是分娩设施(猪的孕育和分娩)，它们产生并对环境贡献最强的雌激素。

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.
