Understanding the Source, Distribution, and Fate of Micro- and Nanoplastics in Natural Water Bodies
AI summary Read the abstract
Sampling, detecting, and characterizing micro- and nanoplastics in natural water bodies presents significant technical challenges that limit our understanding of their environmental hazards. Improved standardized methods for measuring these particles are critical to accurately assessing contamination levels and human exposure risks.
Sampling, separation, detection, and characterization of micro- and nanoplastics dispersed in natural water bodies and other ecosystems is a challenging and critical issue for a better understanding of the hazards for the environment posed by such...

Micro and Nanoplastics in Ecosystems: Interrelated Sources, Risks, Pathways, Consequences, Mitigation, Challenges and Future Recommendations
AI summary Read the abstract
This review maps how micro- and nanoplastics travel between soil, water, and air, accumulate in food chains, and affect living organisms, while also examining mitigation strategies including microbial degradation and better waste management. Understanding these interconnected pathways is critical because plastics carry toxic chemical additives that amplify their health risks as they move through ecosystems.

Fate and Behavior of Microplastics in Freshwater Systems
AI summary Read the abstract
Researchers reviewed how microplastics move, accumulate, and interact with ecosystems in freshwater environments like rivers and lakes, which serve as both major pathways and sinks for plastic pollution. Understanding this behavior is critical because freshwater sources supply drinking water for billions of people worldwide.
Fate and Behavior of Microplastics in Freshwater Systems
AI summary Read the abstract
Freshwater systems accumulate microplastics from multiple pathways including wastewater discharge, atmospheric deposition, and urban runoff, with behavior influenced by particle size, density, and hydrodynamic conditions. Understanding these transport dynamics is critical for assessing human exposure risk through drinking water sources and aquatic food chains.
