Development and Calibration of a New Dripper-Based Rainfall Simulator for Large-Scale Sediment Wash-Off Studies
Researchers designed and calibrated a new rainfall simulator for large-scale experiments studying how rain washes pollutants from land surfaces into waterways. While not directly about microplastics, rainfall simulation tools are used in research on how plastic particles are transported from land to aquatic environments.
Quick analysis of the influence of the monsoon on the concentration of microplastics in the air
Researchers analysed how monsoon rainfall affected atmospheric microplastic concentrations, finding that precipitation events redistributed plastic particles and temporarily increased concentrations of certain polymer types in air samples. The study identifies rainwater as both a carrier and a concentrating medium for atmospheric microplastics.

Researchers analyzed combined sewer overflow event duration monitoring data across England, relating overflow frequency and duration to wastewater system capacity to better understand and manage water pollution from sewer discharges.
Rainfall is a significant environmental factor of microplastic pollution in inland waters
Researchers investigated the role of rainfall as a driver of microplastic pollution in inland waters, a factor that had been largely overlooked in previous studies focused on human activities. The study found that rainfall is a significant environmental factor influencing microplastic distribution in freshwater systems, suggesting that non-anthropogenic processes play an important role in how microplastics move through watersheds.
Quantitative Contributions of Climate and Human Activities to Streamflow and Sediment Load in the Xiliugou Basin of China
Researchers analyzed 30 years of data from the Xiliugou Basin in China to quantify how climate change and human activities have affected streamflow and sediment transport. The study found that human activities, particularly land-use changes, were the dominant factor driving decreases in both streamflow and sediment load, with an abrupt shift occurring around 1997.

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.
