Global multi-pollutant modelling of water quality: scientific challenges and future directions

Researchers argue that tackling global water pollution requires modeling multiple contaminants — microplastics, nutrients, chemicals, and pathogens — simultaneously rather than studying each in isolation. They identify pollution hotspots across Europe, North America, and South Asia where rivers carry dangerous combinations of these pollutants, and call for models that can directly inform policy decisions.

Science and Technology for Water Purification: Achievements and Strategies

This review covers the latest science and technology for purifying water, addressing the global challenges of water scarcity and pollution. It discusses emerging contaminants including microplastics and the treatment methods needed to remove them. The findings are relevant to human health because current water treatment systems may not fully remove microplastics and other new pollutants from drinking water.

Interconnected impacts of water resource management and climate change on microplastic pollution and riverine biocoenosis: A review by freshwater ecologists

Researchers reviewed how river hydrology, water resource management, and climate change interact to influence microplastic pollution in freshwater ecosystems. They found that floods can flush microplastics from catchments, while reservoirs act as both sinks and sources, and extreme weather events driven by climate change tend to concentrate microplastics and threaten aquatic organisms. The study highlights a critical gap in research that jointly addresses these interconnected factors and calls for integrated policy approaches.
