Summary

Quaternary ammonium compounds (QACs) are common disinfectants that enter waterways through household products. Researchers are studying their ecosystem effects using a whole-lake experiment in Canada’s Experimental Lakes Area. By examining microbial communities and other organisms, the project aims to determine how these persistent chemicals affect aquatic ecosystems and inform environmental regulation.
