A Comprehensive Review on Environmental Migration, Physicochemical Transformations, and Exposure-Related Health Risks of Microplastics
This review of over 200 studies found that tiny plastic particles smaller than 5mm are now everywhere in our environment—from ocean water to soil to the air we breathe. These microplastics can carry harmful chemicals and may cause health problems like hormone disruption and chronic diseases when we eat contaminated fish and other foods. The researchers say people may be consuming millions of these plastic particles every week, mainly through seafood, which highlights the need for better waste management and plastic alternatives.
Environmental Transport and Fate Modelling of Micro- and Nanoplastics
This research reviews how scientists track tiny plastic particles (called micro- and nanoplastics) as they move through air, water, and soil in our environment. The study explains different computer models that help predict where these plastic particles end up and how they spread from pollution sources to places where people might be exposed. Understanding how these tiny plastics travel through the environment is important because it helps scientists figure out how much plastic pollution humans might breathe in, drink, or eat.

Microplastics: From Intrinsic Properties to Environmental Fate
This review examines how the built-in properties of plastics — their chemical structure, additives, and molecular weight — determine how quickly they break down in the environment and what happens when they do. As microplastics degrade, they fragment into even smaller particles that may be more harmful because they can more easily enter living organisms. Understanding these degradation pathways is essential for predicting the long-term environmental and health risks of plastic pollution.
