ClearMicroplastic distribution patterns in Kappil Beach sediments, Kerala
Beach sediment samples from Kappil, Kerala in India revealed 766 microplastic particles dominated by nylon fibers (78%), along with polyethylene and polystyrene, with the majority smaller than 1 mm. Risk assessments classified contamination as moderate to high, suggesting active fragmentation of larger plastic debris is ongoing. This baseline data is valuable for tracking pollution trends in Indian coastal ecosystems where fishing and tourism create significant plastic inputs.
