Microplastic Pollution
AI summary Read the abstract
This review summarizes the current state of microplastic pollution across water, soil, air, and food, highlighting their ability to carry other toxins like heavy metals and PCBs. The authors note that microplastics accumulate in the food web, moving from the environment into agricultural products and eventually into the human body. The review emphasizes that a unified, comprehensive approach to studying microplastics across all environmental sources is needed to fully understand the health risks.
Microplastics (MPs) are one of the important emerging environmental pollutants that can be present in different environmental source from water and soil to air. These pollutants have gained attention over the recent years due to their easy degradation process and high bioaccumulation rates in the food web. MPs can transport a variety of pollutants and toxins, including polychlorinated biphenyls (PCBs) and heavy metals, from nature to agricultural products due to their hydrophobic qualities. While MP contamination is often determined in water bodies, soil, air, and food products partially, the whole assessment of MP bioaccumulation and biodegradation chain from nature to the consumer through the food chain still remains well understood. In this chapter, the ecological risks of MP accumulation in terms of biodiversity and sustainability will be evaluated using a holistic approach. Additionally, the current and potential exposure of humans to MP accumulation through the food web is deeply discussed. These holistic approaches offer the opportunity to better understand the detrimental impact of MPs on the ecology and food safety, thus the sustainability of the population.

Microplastics and environmental pollutants: Key interaction and toxicology in aquatic and soil environments
AI summary Read the abstract
This review tracks how microplastics move through soil, water, and air ecosystems, acting as carriers for other pollutants like pesticides and heavy metals. When microplastics absorb these toxins, the combined effect on organisms can be worse than either pollutant alone. The paper highlights the need for better understanding of how these pollutant combinations affect ecosystems and ultimately human health through contaminated food and water.
Microplastic-mediated environmental behavior of metal contaminants: mechanism and implication
AI summary Read the abstract
This review examines how microplastics interact with heavy metals across water, soil, and air environments, acting as carriers that concentrate and transport toxic metals. Researchers found that microplastics can increase the bioavailability and toxicity of metal contaminants to living organisms. The study highlights major gaps in current analytical methods and calls for better tools to understand these complex pollutant interactions.
Microplastics and Nanoplastics and Related Chemicals

This review provides a broad overview of microplastics and nanoplastics as environmental contaminants, covering their sources, distribution across water, soil, and air, and their potential toxic effects on organisms. Researchers summarized evidence showing that these particles can accumulate in food chains and interact with other chemical pollutants, potentially amplifying health risks. The study emphasizes the need for standardized detection methods and comprehensive risk assessments across different environmental compartments.
Microplastics as vectors for environmental contaminants in the food chain: Assessing the combined toxicological effects and bioavailability
AI summary Read the abstract
This review examines how microplastics and nanoplastics act as carriers for environmental pollutants including heavy metals, organic chemicals, and microbial agents as they move through food chains. Researchers detail how polymer type, particle size, and environmental conditions influence the binding and release of these contaminants. The study highlights that the combined toxicity of microplastics together with the pollutants they carry may be greater than either would cause alone.
A comprehensive review on microplastics as vectors of chemical and biological pollutants
AI summary Read the abstract
This review pulls together existing research showing that tiny plastic particles (microplastics) don't just pollute on their own — they can act like sponges, soaking up other harmful chemicals and even microbes from their surroundings and carrying them into the environment and food chain. This matters because plastic-bound pollutants appear to be more toxic and more likely to build up in living organisms than those same pollutants floating freely, raising concerns about how much these "hitchhiking" toxins could affect human health through contaminated food and water. The authors call for more real-world testing to better understand these risks and guide future safety regulations.
