Clear‘‘Spatial distribution, abundance, and risk assessment of microplastics in the surface water of Kaptai Lake: Southeast Asia's largest artificial reservoir’’
Researchers measured microplastic contamination in Kaptai Lake, Southeast Asia's largest artificial reservoir, finding concentrations up to 683 particles per cubic meter of water. Polyethylene and PET were the most common plastic types, and risk assessments indicated serious contamination levels. The findings are concerning because the lake serves local communities for drinking water and fishing, creating direct pathways for human microplastic exposure.
