Sourcing, Timing, and Extent of Microplastic Mobilization by Urban Flooding

Summary

Researchers studied how urban flood events mobilize microplastics stored in urban watersheds, finding that storm flooding dramatically increases the transport of accumulated plastic particles into waterways and downstream environments. As climate change intensifies urban flooding frequency, understanding microplastic mobilization dynamics is critical for predicting pollution loading into aquatic ecosystems and designing stormwater management systems that reduce plastic discharge.
