{"cited_by_count":215461,"description":"This cluster of papers focuses on the fate, behavior, biodegradation, and environmental impact of surfactants and their degradation products in various environmental compartments. It covers topics such as the occurrence, microbial degradation, toxicity, and ecological risks associated with surfactants, quaternary ammonium compounds, chelating agents, and their effects on wastewater treatment processes.","display_name":"Environmental Chemistry and
