Distribution of Microplastics in the Catawba River Basin
AI summary Read the abstract
Researchers mapped the distribution of microplastics across the Catawba River Basin in North and South Carolina, providing baseline data on plastic particle concentrations in an urban river system that supplies drinking water to millions of people in the southeastern United States.

Movement of Microplastics in the Catawba River Basin
AI summary Read the abstract
Researchers tracked the movement and abundance of microplastics throughout the Catawba River Basin, identifying urban runoff, wastewater treatment plant effluent, and stormwater as primary contributors to microplastic loading in this major southeastern U.S. watershed. Rivers function as critical transport corridors that carry microplastics from inland population centers downstream into estuaries and ultimately coastal marine environments.
Microplastic Characterization in the Chesapeake and Delaware Bay Watersheds
AI summary Read the abstract
This study characterized the presence, types, and abundance of microplastics across the Chesapeake and Delaware Bay watersheds, two major estuarine systems on the US East Coast. The results provide a regional pollution baseline and underscore how densely populated coastal watersheds function as concentrated conduits delivering microplastics to ecologically sensitive marine environments.
Microplastic Characterization in the Chesapeake and Delaware Bay Watersheds
AI summary Read the abstract
Researchers characterized microplastic pollution across the Chesapeake and Delaware Bay watersheds, documenting polymer types, particle sizes, and spatial distribution patterns in one of the most ecologically and economically important estuarine systems on the U.S. East Coast. High microplastic loads in these heavily fished and recreationally used waters raise concerns about contamination of commercially harvested seafood and recreational exposure pathways for millions of coastal residents.
The Importance of Plastic Debris as a Source of Microplastics in Richland Creek, North Carolina
AI summary Read the abstract
Researchers investigated how existing plastic debris in Richland Creek, North Carolina fragments and contributes to the standing microplastic load in freshwater, finding that in-stream debris is a major local source of secondary microplastics. In-situ fragmentation of larger plastic litter means that even waterways distant from industrial sources can generate their own microplastic contamination, extending the geographic reach of plastic pollution in drinking water sources.
Occurrence, Distribution, and Removal of Microplastics from Aquatic Ecosystems
AI summary Read the abstract
Researchers investigated the occurrence, distribution, and removal strategies for microplastics in aquatic ecosystems, reviewing how their pervasive presence and resistance to conventional treatment create persistent risks for both environmental and human health.
