Produktbeschreibung

Microplastics in Urban Water Management Enables readers to understand the true occurrence and fate of microplastics in drinking water, wastewater and sludge, and receiving water Microplastics in Urban Water Management focuses on the occurrence, fate, effect, and removal of microplastics in the urban water management systems, summarizing relevant methods for enhancing microplastics removal and degradation, providing comprehensive data from source to sink (including occurrence and fate of microplastics in urban water management), and covering practical applications, which are expected to provide some theoretical guidance for controlling or mitigating microplastics pollution and its environmental risks. The work also includes detailed multidisciplinary information on the way in which microplastics behave in urban water management, plus recent advances of nanoplastics, i.e., nano-sized microplastics, in the aquatic environment. In Microplastics in Urban Water Management, readers can expect to find detailed information on sample topics such as: * Techniques for microplastics detection, including sample collection, purification, identification, and quantitation, plus the definition, emergence, occurrence, and removal of microplastics * Elements of microplastics in wastewater treatment plants; for instance, the ecotoxicological effect on the biological treatment of wastewater and sludge * Why the discharge of microplastics from wastewater treatment plants is the important source of microplastics in the receiving waters * Potential environmental risks of microplastic contamination in receiving water systems and evidence that microplastics can absorb, collect and transport environmental contaminants as vectors For practicing toxicologists, biologists, environmental and chemical engineers, and ecology professionals, as well as researchers and graduate students in these disciplines, Microplastics in Urban Water Management is an essential all-in-one guide to understanding the current state of microplastics in our world and potential solutions for the future.
