This volume provides a collection of research findings on the distribution and risk associated with emerging contaminants (ECs) in water and wastewater across the globe, and effective remediation techniques and technologies. The book covers various monitoring techniques for ECs in water and wastewater and its related impacts on the ambient environment, and offers valuable information on cost-effective monitoring techniques and sustainable treatment technologies for ECs. The authors detail the risks and biological effects of ECs and legacy persistent organic pollutants (POPs) in freshwater and marine systems, including their adverse interactions with aquatic organisms, while also discussing the associated impacts on human health. The book comprehensively covers current research outcomes on treatment methods, cost-effectiveness, and infrastructure needs for effective removal of ECs. It will be of interest to students, researchers, and scholars in environmental science and engineering, water and wastewater, toxicology, environmental biotechnology, soil sciences, and microbial ecology.
