Microplastics and nanoplastics in drinking water and food chain

The worldwide utilization of plastic products has produced enormous quantity of plastic wastes. On entering the environment, plastic wastes continuously break down to small fragments like microplastics (MPs) and nanoplastics (NPs). This chapter provides information on the occurrence of MPs/NPs in drinking water and food items, their source of entry, and detection methods in samples. Current techniques for removal of NPs and MPs in drinking water treatment plants have been discussed with challenges associated with them. Concentration of NPs and MPs in drinking water and food items for different countries have been provided with their impact on human health and aquatic environment. Finally, solutions for precise detection of MPs/NPs in samples and their effective removal in water treatment plants have been provided with future research directions.
