A Review Notes on Role, Behavior, Risk Assessment Tools, and Adverse Outcomes of Metal and Microplastic Pollution in Benthic Sea Food Ecosystem
AI summary Read the abstract
Researchers review the combined effects of metal and microplastic pollution on benthic seafood ecosystems, examining how these co-occurring contaminants affect the health of marine organisms and the humans who consume them, along with the risk assessment tools used to evaluate exposure and outcomes.
It is widely known that marine habitats are exposed to a wide range of pollutants, and a substantial body of research suggests that these pollutants have a severe impact on the health of associated biota and tertiary consumers as well. Methods, approaches, and...

Pollution-Driven Shifts in Marine Ecosystems: The Influence of Heavy Metals, Organic Contaminants and Microplastics
AI summary Read the abstract
Researchers review how heavy metals, organic contaminants, and microplastics interact within marine ecosystems, examining how industrialization and urbanization have driven cumulative pollution shifts that alter species composition, trophic dynamics, and overall ecosystem resilience.
Interactions Between Microplastic and Heavy Metals in the Aquatic Environment: Implications for Toxicity and Mitigation Strategies
AI summary Read the abstract
This review examined how microplastics interact with heavy metals in aquatic environments, showing that temperature, pH, salinity, polymer type, and particle size modulate adsorption, desorption, and combined toxicity, with MPs acting as mobile heavy metal carriers throughout aquatic food webs. Understanding the synergistic toxicity of MPs and heavy metals is essential because their combined effects on aquatic organisms—and on humans consuming contaminated seafood—likely exceed the hazard of either pollutant alone.
The potential of microplastic pellets as a vector to metal contamination in two sympatric marine species
AI summary Read the abstract
This study examined the inflammatory response of human macrophage cell lines exposed to polystyrene microplastics of varying sizes, finding that smaller particles elicited stronger pro-inflammatory cytokine responses than larger equivalents. The size-dependent inflammatory mechanism involved particle internalization via phagocytosis with subsequent lysosomal destabilization and NLRP3 inflammasome activation.
The Effects of Microplastic Pollution on Marine Organisms and its Impact on Human Health: A Review
AI summary Read the abstract
Researchers reviewed how microplastics affect major marine taxa — from plankton to marine mammals — documenting impacts including reduced growth and reproduction, behavioral disruption, and inflammatory responses, while also assessing pathways through which MP-contaminated seafood and drinking water translate ocean pollution into risks for human health.
Interaction of Microplastics and Heavy Metals: Toxicity, Mechanisms, and Environmental Implications
AI summary Read the abstract
Researchers reviewed the combined toxicity of microplastics and heavy metals in the environment, finding that microplastic surfaces readily adsorb metals like lead, cadmium, and copper, creating a dual contamination threat that can amplify toxic effects on organisms beyond what either pollutant causes alone.
