Properties And Performance Of Natural Rubber Latex (NRL) Band: A Scavenging Medium To Capture Microplastic Waste In Water

In recent years, the widespread presence of microplastics in the environment has become a significant challenge, especially to the marine system. The critical concerns are the ecotoxicological impact on marine ecosystems and the potential threat to human organs and tissues. This study was conducted...
