Microplastic Menace
Summary
This chapter reviews the ecological menace posed by microplastics and nanoplastics in aquatic environments, examining how these particles disrupt habitats, food chains, and organisms through pollution and bioaccumulation. The authors assess the capacity of plastic particles to adsorb and concentrate harmful chemicals, compounding the direct physical hazard with chemical toxicity risks for marine food webs.
Microplastics and nanoplastics, particles smaller than 5 millimeters, have induced profound ecological imbalances in aquatic environments, posing threats to habitats, food chains, and organisms through pollution and bioaccumulation. Their capacity to adsorb harmful chemicals raises concerns for aquatic life and human health via contaminated seafood consumption. Furthermore, terrestrial ecosystems are not spared, with soil quality and nutrient cycling impacted by these pollutants. Given their global dispersion through wind and water currents, even remote areas are affected. Addressing these challenges mandates significant actions, including reducing plastic production, improving waste management, and implementing strategies for environmental remediation. Public awareness and education are pivotal for fostering sustainable practices and mitigating the pervasive impact of plastic contamination on ecosystems worldwide.

Unraveling the ecotoxicological effects of micro and nano-plastics on aquatic organisms and human health
This review summarizes the growing body of evidence on how micro- and nanoplastics affect aquatic organisms and, through the food chain, potentially human health. The tiny plastic particles absorb toxic pollutants and pathogens from the water, acting as carriers that deliver these harmful substances into the bodies of fish, shellfish, and other organisms. The review highlights that both direct plastic toxicity and indirect chemical exposure through contaminated seafood pose risks to human consumers.
