Microplastic Pollution in Waters and Sediments in a Lentic System: A Case Study in a Tropical Wet Urban Lake of Samarinda, Indonesia
Researchers sampled water and sediment from a tropical urban lake in Samarinda, Indonesia, finding microplastic contamination at all 10 sampling sites with an average of 0.91 particles per litre in water and 375 particles per kilogram in sediment.

Water quality and floating microplastics pollution along Southern to Northwestern Coast, Sri Lanka
Researchers surveyed microplastic levels and water quality at 12 coastal sites along Sri Lanka's western and southern coast, finding microplastics present at all locations with fibers being the dominant form. The study also found correlations between microplastic abundance and certain water quality parameters, suggesting that areas with poorer water quality tended to have higher plastic loads. The research adds to growing evidence that South Asian coastal waters are significantly contaminated with microplastics, with potential implications for marine food webs and fishing communities.
