Microplastics in freshwater environments

Résumé

Plastic pollution in aquatic environments is a recognized environmental threat on the global scale and is fed by the linear economy model of "make-use-dispose" which underpins both fossil fuel and plastic industries. This chapter examines the issue of microplastic pollution in different freshwater environments namely (1) rivers and tributaries, (2) lakes, (3) groundwater sources (4) glaciers and ices caps, and (5) deltas. Particular challenges, the geographical coverage of studies, and current knowledge gaps are highlighted for each freshwater category based on the currently available peer-reviewed literature. Sources and distribution of microplastics in freshwater bodies and associated repercussions to freshwater ecosystems and human health are also reviewed. A better understanding of microplastic interactions between human settlements and freshwater environments in different parts of the globe is required to better enact evidence-based mitigation measures which will be able to further limit the spread of microplastic pollution in the natural environment. Therefore, research on microplastic pollution in freshwater bodies around the world must be further supported to provide a reliable global database and compliant monitoring procedures. Additionally, further research can better inform policies and regulations around plastic use and emission into the environment at both the global and local scales.
