Interactions Between Microplastics and Heavy Metals in Aquatic Environments: A Review

Area of Science:

• Environmental Science
• Ecotoxicology
• Microbiology

Background:

• Microplastics (MPs) are pervasive environmental contaminants.
• MPs can adsorb and transport heavy metals in aquatic ecosystems.
• The interactive mechanisms between MPs, heavy metals, and biota are not fully understood.

Purpose of the Study:

• To review and analyze the interactions between microplastics and heavy metals.
• To investigate the role of microorganisms in these interactions.
• To assess the combined toxic effects and risks to human health.

Main Methods:

• Bibliometric analysis of existing research.
• Examination of interaction mechanisms, focusing on microbial roles.
• Discussion of toxic effects and human health hazards.

Main Results:

• Microorganisms significantly influence the interactions between MPs and heavy metals.
• Combined exposure poses potential risks to living organisms.
• Current understanding of mechanisms and risks requires further investigation.

Conclusions:

• Microbes are essential players in MP-heavy metal interactions.
• Further research is needed to elucidate mechanisms and mitigate risks.
• Addressing MP contamination is critical for environmental and human health protection.
