The Department of Aquatic Biology and Fisheries at the University of Kerala conducted the study “Microplastic pollution in Ashtamudi Lake (India): Insights From a Ramsar Wetland” with the support of the Ecomarine Project, co-funded by Erasmus program of the European Union.

The Southern Bench, consisting of Dr. Satyagopal Corlapati and Justice Arun Kumar Tiagi, both judicial members, said that the case had been registered suo motu due to the seriousness of the matter reported in the newspaper.

Microplastic fibers made up 35.6% in the samples collected. The list was followed closely by films (28%) and fragments (33.3%). The samples were analyzed in detail to reveal the presence of hazardous heavy metals and plastic polymers. The microplastics in fish and shellfish guts were composed of nylon, polyurethane polypropylene polyethylene and polysiloxane.
