This review examined the origin, fate, and impacts of nano- and microplastics in water and wastewater treatment processes, finding that small particle sizes and diverse polymer compositions make complete removal challenging across conventional and advanced treatment stages. The authors identify detection limitations and process instability as key barriers to effective water treatment for nanoplastics.
Where do they go? A review of the wastewater treatment process and its impact on the fate of microplastics
This review examines the fate of microplastics across the physical, chemical, and biological stages of wastewater treatment plant (WWTP) processes, finding that WWTPs act as both sources and destinations for microplastics while not being designed to remove them, and surveying new removal strategies.
Detection and removal of microplastics in wastewater: evolution and impact
This review covers methods for detecting and removing microplastics from wastewater, which is a major pathway for microplastics to enter the environment. Microplastics in water can carry heavy metals, disease-causing organisms, and chemical additives, and are eventually consumed by aquatic life that enters the human food chain. The authors emphasize that better wastewater treatment technology is needed to reduce human exposure to microplastics through water and seafood.
