Occurrence And Fate Of Microplastics In Urban Freshwater Systems
Summary
Microplastics were found in urban freshwater pond sediments at highly variable concentrations, with buoyant particles dominating by mass and water mixing playing a key role in distributing plastic particles through the water column.
MP content in the pond sediments varied up to two orders of magnitude.• Buoyant MPs made up 95.4 % of the MPmass and 83.5 % of the MP-number.• No trend in the spatial distribution of MPsneither concentration, size, nor polymer • Mixing is an important factor for transporting buoyant MPs to the pond sediments.• Sediment contents of silt and organic matter correlate with the MP-distribution.

Buoyant microplastics in freshwater sediments – How do they get there?
Microplastics were found to accumulate in the sediments of a stormwater treatment pond at average concentrations of 44,383 items per kg, with highly uneven spatial distribution reflecting hydrodynamic deposition patterns within the pond. The study provides insight into how stormwater infrastructure captures microplastics and what fraction may still pass through to receiving waters.
Urban tropical freshwater ponds as microplastics hotspots—insight on abundance and characteristics using an improved sampling technique
Researchers surveyed 20 urban freshwater ponds in central India and found microplastics present in all of them, with fragments, films, and foams being the most common types. They introduced an improved, low-cost sampling technique that does not require boats, making it practical for studying smaller water bodies. The results confirm that urban ponds are significant hotspots for microplastic accumulation, with polyethylene and polystyrene being the dominant polymer types.
Microplastics in a Stormwater Pond
Researchers analyzed microplastics in the water, sediments, and vertebrate fauna of a stormwater retention pond, finding widespread microplastic contamination across all compartments with the pond appearing to act as a sink that concentrates microplastics from urban runoff.
Microplastic Pollution in Surface Waters and Sediments of Urban Lake
This book chapter reviews microplastic pollution in urban lake surface waters and sediments, describing sources, distribution patterns, and the ecological consequences of MP accumulation in these widely used but understudied freshwater habitats.
Anthropogenic Litter in Urban Freshwater Ecosystems: Distribution and Microbial Interactions
Researchers quantified anthropogenic litter in urban rivers and streams and found that microplastics dominated by mass and particle count compared to macroplastic items. The study highlights urban freshwater systems as major conduits for plastic pollution moving toward marine environments and documents distinct microbial communities on plastic surfaces.
