This review synthesizes the scientific basis for monitoring and remediating marine micro- and nanoplastic pollution, covering detection technologies, ecotoxicological effects across the food web, and the specific challenges nanoplastics pose due to their nanoscale properties.
Impact of plastic contaminants on marine ecosystems and advancement in the detection of micro/nano plastics: A review
This review summarizes how micro and nanoplastics harm marine life at every level of the food chain, from algae to fish, causing neurotoxicity, gut inflammation, and reproductive damage. The authors also review advances in detection technology, including sensors that can identify tiny plastic particles in water. Understanding how microplastics accumulate through marine food webs is critical because seafood is a major pathway for human microplastic exposure.
