ClearStorm events as key moments of microplastic contamination in aquatic ecosystems
Researchers monitored microplastic concentrations in waterways before, during, and after storm events and found that storm-driven runoff caused major spikes in microplastic abundance, identifying storm events as key transport moments that standard monitoring programs typically miss.
Underestimated land-to-sea microplastic emissions: The crucial role of rainfall events
Researchers investigated microplastic emission characteristics during a rainfall event in Masan Bay, Korea, using time-weighted sampling in the Samhochoen stream to capture temporal variation in microplastic loads. They found that microplastic abundance peaked during early runoff stages and was strongly influenced by rainfall intensity, with polypropylene and polyethylene accounting for roughly 60% of detected polymers.
The impact of extreme weather events on microplastics in intertidal sediments within a coastal embayment.
Researchers sampled microplastics in intertidal sediments of a coastal embayment before and after an extreme weather event to capture temporal variability. Microplastic concentrations increased substantially following the event, suggesting storms mobilize plastic from terrestrial and coastal sources and can cause short-term spikes in marine microplastic loads.

Key risk factors were identified based on particle characteristics, with the study providing insights for managing microplastic impacts in this heavily urbanized coastal environment.
Microplastics discharged from urban drainage system: Prominent contribution of sewer overflow pollution
Researchers evaluated the abundance and distribution of microplastics in urban drainage systems in coastal Chinese cities, with a focus on sewer overflow events during storms. The study found that overflow pollution during wet weather is a prominent contributor to microplastic discharge into urban water bodies, with meteorological conditions and land use patterns significantly influencing microplastic transport and release.
Inter-event and intra-event dynamics of microplastic emissions in an urban river during rainfall episodes
Researchers conducted high-frequency sampling of microplastics in a Japanese urban river during three different rainfall events to understand how storms mobilize plastic pollution. They found that rainfall events increased microplastic loads by 4 to 110 times compared to dry weather, with smaller particles mobilizing first during lighter rains and larger particles surging after peak rainfall intensity. The study reveals that storm dynamics play a critical role in determining when and how microplastics are flushed from urban areas into waterways.
Microplastic Variations in Land-Based Sources of Coastal Water Affected by Tropical Typhoon Events in Zhanjiang Bay, China
Researchers analyzed the abundance, composition, diversity, and flux of microplastics from three estuaries and one sewage outlet in Zhanjiang Bay, China, before and after tropical typhoon events, finding a 3.6-fold increase in microplastic abundance from land-based sources following typhoons. The study links increased stormwater discharge during typhoons to elevated microplastic loading in coastal waters, highlighting how climate-driven extreme weather amplifies plastic pollution.
Impact of persistent rain on microplastics distribution and plastisphere community: A field study in the Pearl River, China
Researchers studied the Pearl River in China and found that persistent rain increased the amount and variety of microplastics in surface water while decreasing them in sediments. The heavy rainfall stirred up settled particles, temporarily turning river sediments from microplastic sinks into sources. The study highlights how weather events can redistribute microplastic pollution and alter the microbial communities that grow on plastic surfaces.
Seasonal variation of diversity, weathering, and inventory of microplastics in coast and harbor sediments
Seasonal variation in microplastic diversity, weathering degree, and abundance was characterized in coastal and harbor sediments along the southwestern coast of Taiwan, finding harbor sites more contaminated than coastal areas and summer monsoon rains driving seasonal fluctuations.
Rainfall and Tidal Cycle Regulate Seasonal Inputs of Microplastic Pellets to Sandy Beaches
Researchers assessed how rainfall and tidal cycles regulate seasonal inputs of microplastic pellets to sandy beaches at regional and local scales, using pellets as a proxy pollutant to quantify spatio-temporal variation in stranding patterns near port facilities and industrial sites. Results showed that rainfall-driven runoff and tidal dynamics are primary controls on pellet delivery to beaches, with implications for managing industrial microplastic releases to coastal environments.
