BENTHIC MICROBIAL COMMUNITIES AS INDICATORS OF ECOLOGICAL DISRUPTION BY PHARMACEUTICALS AND PERSONAL CARE PRODUCTS
Pharmaceuticals and personal care products (PPCPs) are biologically active compounds that are present in freshwater ecosystems throughout the world. At current environmental concentrations, PPCPs are generally not toxic, but the production of synthetic chemicals, including PPCPs, is increasing a rate greater than those of other agents of global change. Furthermore, the ability of these compounds to disrupt ecological processes in freshwater ecosystems is often overlooked, and ecological disruption is generally not considered as part of regulatory criteria. We will discuss our research demonstrating that exposure to environmentally relevant concentrations of a variety of PPCPs can alter the activity, taxonomic, and genomic composition of benthic microbial communities. Due to the critical role that microbes play in streams, these findings have significant implications for the health of these ecosystems and are indicative of ecological disruption. Therefore, we suggest that benthic microbial communities can be useful indicators of ecological disruption by pharmaceuticals and personal care products and should be considered in the evaluation of the environmental safety of these compounds.
