Microplastic Pollution Mitigation from Fresh and Marine Water Bodies
AI summary Read the abstract
This review examines natural processes that remove microplastics from aquatic environments and discusses mitigation strategies to reduce the input of microplastics through treated wastewater discharges. The chapter notes a significant discrepancy between estimated microplastic inputs to the ocean and the much lower quantities actually measured, suggesting active removal mechanisms warrant further investigation.
Microplastics constitute a widespread and ever-increasing pollutant in global water systems. Notably, the estimated amount of microplastics in the ocean is much less than the estimated input. The natural processes that make microplastics disappear from the water environment and ways to mitigate the extent of microplastics entering into water systems with treated wastewater are discussed. This chapter describes in detail microplastic contamination mitigation methods from fresh and marine water bodies.

AI summary Read the abstract
This review provides a comprehensive look at how microplastics enter, move through, and are removed from wastewater treatment plants. Researchers found that while treatment processes can remove a significant portion of microplastics from water, large quantities still escape into rivers and oceans. The study highlights the need for improved treatment technologies and better monitoring to reduce microplastic discharge from these facilities.

Microplastics in Wastewater Treatment Plants: Characteristics, Occurrence and Removal Technologies
AI summary Read the abstract
This review summarizes how wastewater treatment plants are a major pathway for microplastics entering the environment, covering the types, sizes, and sources of microplastics found in wastewater. While treatment plants can remove many microplastics, significant amounts still escape into rivers and oceans through treated water and sludge. The authors evaluate various removal technologies and recommend advanced treatment methods to better prevent microplastics from reaching water supplies.
