Impacts

The primary outcome of this research was the development of extraction and analytical methods for quantifying antibiotics from various media, including wastewater, soils and manure. This aspect of the work was considerably more extensive than anticipated, and has provided us with a strong foundation to conduct ongoing research by our research team and pursue further funding sources. Less abstract, we have provided a range of deliverables and continue to produce publications.

We have achieved our short-term impacts of increasing knowledge of antibiotics in manure management systems and continue to develop materials that contribute toward our intermediate and long-term expected impacts.
