Microplastic pollution is a significant concern
Research gap analysis derived from 3 chemistry papers in our local library.
The gap
Microplastic pollution is a significant concern in tropical rivers. The presence of high-hazard polymers elevates polymer-based risks and increases PERI values. Effective management of microplastic pollution in tropical rivers is needed.

Some attention has been drawn to additives and persistent organic pollutants that sorb to the plastic surface, but so far the chemicals generated by degradation of the plastic polymers themselves have not been well studied from an environmental perspective.

Further research is needed to fully understand the effects of biodegradable plastics on the environment. Studies should investigate the potential negative environmental impacts of biodegradable plastics, such as microplastic formation and greenhouse gas emissions. Research should focus on developing more sustainable and environmentally-friendly alternatives to traditional plastics.
