Project ID: 2011ND242B One major Research Question of this project is: Does E2 bound to DOC/COC have the same estrogenic potency as aqueous dissolved E2? This research question is essential, because it is apparent that one of the major fate and transport mechanisms of E2 in and to surface and subsurface water resources is related to its association with DOC/COC. 17Β-estradiol is very potent, and animal agriculture is a major source of this compound. A benefit of the proposed project will be to identify whether E2 bound to DOC/COC is a cause of concern. Furthermore, this proposed study will provide a new tool to this research area, which might be used to quantify the relative estrogenicity of hormone detections in the environment. This connection between toxicological significance and environmental detections of estrogens and other hormones is severely needed. To date, there is no real objective data that provides toxicological implications of hormone detections in the environment. Additionally, this research will be beneficial in the context of manure management, and the resulting fate and transport of E2 from manure and its impacts the receiving water quality. The association of estradiol to certain organic carbon fractions can provide insight into how to properly manage manure. |
