Impact/Purpose:
Presentation to the Consortium for Research and Education on Emerging Contaminants October 2021.
Description:
The lack of established water quality criteria or guidelines for many contaminants of emerging concern (CECs) in surface waters represents a significant challenge to state and regional risk assessors charged with protecting our nations waters and associated aquatic ecosystems from harmful impacts of toxic chemicals. The present study demonstrates how data and tools from new approach methodologies for chemical safety assessment can be employed to characterize the spatial extent and temporal variability of toxicologically relevant biological activity of complex mixtures of contaminants present in surface water. The approaches inform identification of priority chemicals that may warrant further as well as potential effects to monitor in organisms exposed in situ. As such, the tools and approaches demonstrated in the present study can be adopted by Regional, state, and local authorities to aid in evaluating the potential impacts on contaminants on their natural resources and guide investments in future monitoring and management.
