Hundreds of millions of microplastic particles could be flowing into UK rivers, hidden in raw sewage

Summary
Researchers found that raw sewage discharged into UK rivers may be carrying hundreds of millions of microplastic particles, suggesting that current estimates of environmental microplastic levels are significantly underestimated. This finding points to wastewater infrastructure as a major and underappreciated pathway for microplastics entering freshwater systems.
The amount of microplastics in the environment is being significantly underestimated, research shows.
