Plastics in the marine environment are introduced through multiple pathways, and pose serious threats to aquatic biota. Recently microplastic pollution and its possible consequences in India have been recognized by the scientific community, however the extent of the crisis has not yet been quantified. The present study attempted to ascertain the abundance, distribution and characteristics of microplastics in coastal waters (14 locations), beach sediments (22 locations) and marine fishes (11 locations) from the state of Kerala, southwest coast of India. The results showed that the mean microplastic abundance was 1.25 ± 0.88 particles/m3 in coastal waters and 40.7 ± 33.2 particles/m2 in beach sediments with higher concentrations in the southern coast of the state. The abundance of microplastics, mostly contributed by fragments, fibre/line and foam, in both coastal waters and beach sediments, were highly influenced by river runoff and proximity to urban agglomeration. Fourier Transform Infrared Spectroscopy-Attenuated Total Reflection (FTIR-ATR) revealed that polyethylene (PE) and polypropylene (PP) were the dominant polymers in the marine environment. The digestive tracts of 15 out of 70 commercially important fishes studied, contained 22 microplastic particles. Polyethylene (PE; 38.46%) followed by cellulose (CE; 23.08%), rayon (RY; 15.38%), polyester (PL; 15.38%) and polypropylene (PP; 7.69%) were the major contributors in the fish ingested microplastic composition. A broad range of heavy metals, metalloids and other elements that are potentially indicative of hazardous chemicals were present in microplastics collected from the beaches of Kerala. These results enhance our understanding on the sources, transport pathways and the associated environmental risks of microplastics to marine ecosystems.
Guidelines on Extended Producer Responsibility for Plastic Packaging. These guidelines provides framework for implementation of Extended Producer Responsibility. The Guidelines provide the roles and responsibilities of Producers, Importers, Brand Owners, Central Pollution Control Board, State Pollution Control Board or Pollution Control Committees, recyclers and waste processors for effective implementation of Extended Producer Responsibility.

The Policy Brief gives an overview of the current waste management related policy ecosystem and provides preliminary recommendations based on desk research, specifically on marine litter in India.
The Government of India announced the Plastic Waste Management Amendment Rules, 2021, which will prohibit the manufacture, import, stocking, distribution, sale and use of single use plastics (including polystyrene and expanded polystyrene) by 2022. To stop litering and promote reuse, the thickness of plastic carry bags have been increased. Please note that “English text follows[…]
Environment ministers around the globe agreed to create an Intergovernmental Negotiating Committee to create an international agreement to end plastic pollution at the fifth United Nations Environment Assembly (UNEA), held in Nairobi, Kenya, between February 28 and March 2, 2022.
Developing country facilities, financial and human resources prevent complete application of sampling, analysis, and observation protocols used in developed countries neccitating adaptations. Researchers in Vietnam developed and standardized a methodology for microplastic monitoring in sediments and surface waters of 21 environments (rivers, lakes, bays, beaches) of eight cities or provinces. The concentrations of microplastics in[…]
