Microplastic contamination in urban aquatic environments: Occurrence characteristics in urban streams and stormwater runoff from urban surfaces
Researchers examined microplastic contamination in urban streams and stormwater runoff across different seasons and found that wastewater treatment plant discharges were a major source during dry weather. During rainy periods, stormwater runoff from roads and rooftops contributed additional microplastics, predominantly fibers and fragments. The study highlights that urban water systems receive microplastic pollution from multiple pathways year-round.

Researchers quantified and characterized microplastics in seasonal surface water samples from the Akkulam-Veli lake catchment in Kerala, India, finding highest concentrations during pre-monsoon (5100 particles/m3) and lowest during post-monsoon (1838 particles/m3), indicating seasonal and hydrological drivers of microplastic distribution.
Seasonal Abundance and Distribution Patterns of Microplastics in the Lis River, Portugal
Researchers investigated seasonal microplastic abundance and distribution in Portugal's Lis River Basin across nine sites, finding fibres and fragments dominated in both water and sediment, with polyethylene the most common polymer in water. Population density, plastic processing companies, and meteorological factors were all associated with seasonal variation in microplastic patterns.
Microplastic Levels in Water and Sediment of Karaçomak Dam Lake (Kastamonu, Türkiye)
Microplastic abundance in water and sediment samples from Karaçomak Dam Lake in Turkey was assessed across four seasons in 2023. MPs were detected in all samples, with fibres predominating, and concentrations varied seasonally, raising concern for a drinking and irrigation water source affected by plastic pollution.
Microplastics in Turkish coastal lagoons: Unveiling the hidden threat to wetland ecosystems
Researchers conducted the first comprehensive assessment of microplastic pollution in five coastal lagoons in northeastern Mediterranean Turkey, recovering over 15,500 microplastic particles from water and sediment samples. Water concentrations were significantly higher in November than in June, with fibers being the dominant type and polyethylene, polypropylene, and polyester the most common polymers. The findings point to agricultural runoff, fishing gear, and mismanaged waste as significant pollution sources in these ecologically important wetland ecosystems.
A comprehensive evaluation of microplastic pollution in the Xiangshan Bay of China with special reference to seasonal variation
Researchers surveyed microplastic pollution in the semi-enclosed Xiangshan Bay in China across spring and summer seasons. The study found that microplastic abundance in surface water was significantly higher in summer than spring, with different pollution sources dominating each season — textile industry in spring and fishery production in summer — suggesting seasonal human activities strongly influence microplastic contamination patterns.
Spatiotemporal variation in microplastic contamination along a subtropical reservoir shoreline
Researchers tracked microplastic contamination along the shoreline of a subtropical reservoir over two years and found that microplastic abundance was higher near urban areas and varied with season, with storm-related inputs creating significant temporal spikes.
Spatiotemporal distribution of microplastics in the catchment of lake akkulam-veli, kerala, india
Researchers quantified and characterised microplastics in surface water samples from the Akkulam-Veli lake basin in Kerala, India, collected across three seasons — post-monsoon, monsoon, and pre-monsoon — to assess spatiotemporal variation. Results showed pre-monsoon had the highest concentrations (5,100 particles/m3), fibres and films were dominant forms, and FTIR confirmed the presence of polypropylene and other polymers.
