Objective:
The objective of our research is to assess the occurrence, fate and transport of natural and synthetic steroid hormones at beef and dairy cattle confined animal feeding operations (CAFOs). As part of our project, we are focusing on steroid hormone transport through surface water runoff and groundwater.
Progress Summary:
Future Activities:
During the coming year, we plan to continue our efforts to understand the transport of steroid hormones in surface runoff and groundwater. Additional runoff microcosm experiments will be conducted to observe the effect of higher manure concentrations, equilibration time, and microbial community on endogenous steroid stability. Experiments observing the effects of moisture and shade on synthetic steroid stability in feedlot soil are also being conducted. An additional experiment observing TBA metabolite excretion in various breeds of cattle as a function of time also is being conducted. Data analysis for these experiments is ongoing.
