Himalayan lakes can potentially become long-term sinks of microplastics
Posted on 27 Aug, 2022 03:36 PMMicroplastic pollution is a growing environmental concern. Microplastics are plastic particles with sizes ranging from 1 μm to 5 mm. However, a clear consensus on the definition of microplastics is lacking and even the lower size limit varies among different studies.

Heavy metals being discharged into coastal waters
Posted on 22 Aug, 2022 12:26 AMIn recent years, the impact of the wastes discharged in the Bay of Bengal has been significant due to high effluent inflow from secured sources. It was observed that the heavy metal concentrations in the Bay coast sediments were considerately high and varied among sampling points.

Heavy metal contamination in the sediments of the Brahmaputra river
Posted on 16 Aug, 2022 10:11 AMThe river Brahmaputra carries around 73 million tons of dissolved material annually, which accounts for approximately 4% of the total dissolved flux into the oceans (Singh et al., 2005). The dissolved chemical load and sediment flux of the Brahmaputra River has significantly higher rates of physical and chemical weathering than other large Himalayan catchments.

Arsenic removal in groundwater
Posted on 12 Aug, 2022 11:14 PMSafe drinking water, a global concern
The safety and accessibility of drinking water is a global concern. The World Health Organisation (WHO) reports that 80 percent of diseases are waterborne. Contamination from the geological formations (termed geogenic contamination) is the major source of groundwater contamination.
