The Individual and Combined Effects of Microplastics and Heavy Metals on Marine Organisms
AI summary Read the abstract
This review summarizes how microplastics and heavy metals individually and together affect marine organisms. Microplastics can absorb heavy metals from the water and carry them into organisms, creating combined toxic effects that are often worse than either pollutant alone. Since these contaminants accumulate up the food chain and end up in seafood, this combined pollution poses a potential threat to human health through diet.
Microplastics (MP) have recently become an emerging problem with the advent of bountiful and widespread pollutants in the aquatic environment. Owing to their large surface areas, microplastics act as an effective carrier of heavy metals and tend to form complex contamination. This combined pollution created by them poses a new threat to the world. This review summarizes the effects of microplastics and heavy metals on the aquatic fauna, along with their combined adverse effects and potential threats to human health. Furthermore, the adsorption kinetics adopted by microplastics to adsorb the heavy metal is also explained and some future research directions in this field are suggested.

The Unseen Threat of the Synergistic Effects of Microplastics and Heavy Metals in Aquatic Environments: A Critical Review
AI summary Read the abstract
This review examines how microplastics and heavy metals interact in water environments, finding that microplastics can attract and concentrate toxic metals on their surfaces through various chemical forces. This combination effect is a concern for human health because contaminated microplastics carrying heavy metals can be consumed through seafood, delivering a double dose of pollutants.
A critical review on the interactions of microplastics with heavy metals: Mechanism and their combined effect on organisms and humans
AI summary Read the abstract
This review examines how microplastics interact with heavy metals in the environment and what their combined effects mean for organisms and human health. Microplastics absorb heavy metals from surrounding water and soil, and when ingested, the acidic conditions in the gut can cause those metals to be released inside the body. The combination of microplastics and heavy metals may be more toxic than either pollutant alone, creating a compounded health risk.
Heavy metals and metalloid in aquatic invertebrates: A review of single/mixed forms, combination with other pollutants, and environmental factors
AI summary Read the abstract
This review examines how heavy metals affect aquatic invertebrates, both alone and in combination with other pollutants like microplastics. When heavy metals attach to microplastics, the combined effect on organisms can be greater than either pollutant alone. Since these contaminants accumulate up the food chain, they ultimately pose risks to human health through seafood consumption.
A review on the combined toxicological effects of microplastics and their attached pollutants
AI summary Read the abstract
Researchers reviewed how microplastics act as carriers for other environmental pollutants — including heavy metals and persistent organic chemicals — and how these combinations produce toxic effects in organisms that are more severe than either contaminant alone. The findings highlight a complex, layered toxicity problem that affects microbes, invertebrates, and vertebrates across marine and terrestrial environments.
Co-occurrence and Interaction of Microplastics with Heavy Metals
AI summary Read the abstract
This review examines the co-occurrence of microplastics and heavy metals in aquatic and terrestrial ecosystems, synthesizing evidence on how MPs adsorb metals, alter their bioavailability, and facilitate their transfer up food chains, compounding toxicological risks beyond either pollutant alone.
