Abundance and Characteristics of Microplastics in Urban Drainage Canals of Dhaka City, Bangladesh
AI summary Read the abstract
Researchers assessed microplastic contamination in urban drainage canals in Dhaka, Bangladesh, finding significant accumulation that turns these waterways into conduits transporting microplastics into riverine and marine ecosystems, posing risks to aquatic life and human health in one of the world's most densely populated cities.
Microplastics (MP) contamination of urban waterway bodies like canals is a growing concern, which acts as pathways for MPs to reach riverine and marine ecosystems, posing threat to aquatic ecosystems and human health. Urban canals become a source of MPs due to...
