Microplastics in Weras Ganga, Bolgoda North Lake, Sri Lanka: A Reflection of Urban Waste Mismanagement

Researchers analyzed microplastic pollution in a river and lake system near an open waste dump in Sri Lanka and found microplastics present in all water and sediment samples. Over half of the particles were fibers, and smaller microplastics dominated near the dump site, with sediments acting as a major sink for contamination. The study highlights how inadequate waste management practices directly contribute to microplastic pollution in urban waterways.

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.

Spatial distribution of microplastic concentration around landfill sites and its potential risk on groundwater

Researchers found microplastic contamination in groundwater near two municipal waste dump sites in South India, with levels ranging from 2 to 80 particles per liter. Nylon was the most common type found, making up 70% of particles, and the contamination was traced back to degrading buried plastic waste. This is concerning because many communities rely on groundwater for drinking, and these findings show landfills can be a direct source of microplastics in drinking water.
