[Occurrence Characteristics and Ecological Risk Assessment of Microplastics in Sewage Sludge across China].

Summary

Researchers found high levels of tiny plastic particles (microplastics) in sewage sludge across China, and their analysis shows this pollution poses a serious risk to the environment. This matters because sludge is often used as fertilizer on farmland, meaning these microplastics could end up in our soil, water, and potentially the food we eat—making better waste treatment and pollution controls an important public health priority.
