Micro and nano-plastics pollution in freshwater ecosystems: Sources, risks and mitigation strategies
AI summary Read the abstract
This review synthesizes global research on micro- and nano-plastic (MNP) contamination in freshwater ecosystems, cataloging the diverse sources of MNPs and the threats they pose to aquatic wildlife and human health via drinking water and food chains. Identifying mitigation strategies for freshwater systems is critical given that rivers and lakes serve as both sinks and transport vectors delivering microplastics to the ocean.
Micro and nano-plastics (MNPs) are pervasive pollutants ranging in size from 1mm and 1nm respectively. MNPs are entering in aquatic ecosystem by various means and posing significant threats to the ecosystem functioning, wildlife and human health. Due to the excessive use of plastic, we are generating a huge plastic waste everywhere and the generated waste also gets accumulated in our water bodies. Various studies have been conducted worldwide, confirming the presence of micro and nano-plastics (MNPs) in water bodies, however the sources of their origin vary accordingly and associated risks are still less talked about. This review paper highlights various sources of MNPs and their influence on aquatic freshwater ecosystem and dependent species. It also focuses on suggesting strategies which can be implemented to minimize the MNPs pollution.
