Summary

Researchers reviewed how sewage treatment plants handle microplastics, finding that while these facilities remove a large fraction from wastewater, they also concentrate microplastics in sewage sludge that is then spread on agricultural land — potentially transferring plastic pollution from water to soil and food systems.

Microplastics (MPs), usually plastic fragments smaller than 5 mm in size, are ubiquitous in the environment and pose an increasing threat to the entire ecosystem as an emerging micropollutant. MPs not only contribute to the accumulation of the plastics in the...
