Summary

This review paper explains how plastic waste, including tiny fragments called microplastics, ends up polluting our rivers and oceans, often through everyday sources like washing machine runoff from synthetic clothing and tire wear from cars. It highlights that our current recycling system isn't equipped to handle all this waste, meaning much of it escapes into the environment where it can eventually make its way into water, food, and potentially our bodies. Understanding these pollution pathways is a key first step toward developing better solutions to reduce our exposure to microplastics.

Large-scale production and use of plastics began around 1950, and since then they have become increasingly ubiquitous materials due to their combination of useful properties, including cost-effectiveness, low density, ease of processing, water-resistance, and durability. Microplastics in environmental samples are frequently categorized in terms of their chemical identity, color, and morphology. Despite improvements in recycling technology, the plastics economy is largely linear; some plastics are unsuitable for recycling, many plastic items are improperly disposed of by users, either as litter or into incorrect waste streams, and potentially recyclable plastic waste is sent to landfill or discharged to rivers and oceans on enormous scales. water treatment plants are significant point sources of microplastic contamination into the aquatic environment, deriving from sources including fibers and fragments of artificial textiles in washing machine run-off, and particles from tire wear and other plastic fragments on urban surfaces.
