Summary

Researchers analyzed microplastics in sewage sludge from a wastewater treatment plant in Shaanxi, China, finding that 97% of particles were smaller than 400 micrometers, with PVC (polyvinyl chloride) making up the largest share — a particularly concerning finding given PVC's higher toxicity risk index. The study underscores how sewage sludge acts as a major accumulation point for microplastics, concentrating pollution that can then spread when sludge is applied to farmland.

Microplastics (MPs), as a new type of pollution, could result in serious environmental pollution due to its special properties. Meanwhile, the damage of MPs to environment could be reflected by the MPs characteristics in sewage sludge, one of dominant sinks of MPs. Therefore, this study investigated the abundance and characteristics of MPs of sewage sludge derived from Yangling, Shaanxi province. Results showed that among of all detected MPs, the particle size ranged from 8 μm–1 mm, especially 8–400.00 μm, accounting for 97.27%. Moreover, the microplastics were dominantly in the shape of fragment in white. Additionally, 41.18% of the microplastics were identified as PVC, which led to higher risk index in Yangling. Furthermore, human density, human activities, environmental factors, and industrial types were responsible for the different details of microplastics in sewage sludge. Concluded from these results, more attention is supposed to pay on MPs pollution in Yangling zone.
