Chemical Technologies to Degrade Microplastic Pollution
AI summary Read the abstract
Researchers reviewed chemical methods for degrading microplastics in the environment, including oxidation, photocatalysis, and other advanced treatment technologies. These approaches could eventually help remove the billions of plastic particles already polluting water, soil, and food sources worldwide, though most remain in early experimental stages.
Microplastics (MPs) are semisynthetic plastics having diameter less than 5 mm and considered as one of the most abundant pollutant in environment. MPs become part of the environment by the breakdown of larger plastics or through the release of plastic feedstock like...
