Microplastics were detected in animal tissues at levels that raise potential consumer safety concerns, though current detection methods are prone to contamination.
Sources, effects and present perspectives of heavy metals contamination: soil, plants and human food chain
This review summarizes how heavy metals like lead, cadmium, and arsenic contaminate soil, get absorbed by crops, and enter the human food chain. Heavy metals at high levels can damage plant growth and accumulate in food at concentrations unsafe for human consumption. This is relevant to microplastics research because microplastics in soil can bind and transport heavy metals, potentially increasing the amount that ends up in the food we eat.
Impact of Microplastics on Livestock: Sources, Exposure Pathways, and Physiological Consequences
This review examined how microplastics enter livestock systems through contaminated soil, water, and feed, and assessed the resulting risks to animal health, food safety, and agricultural sustainability. The review highlights that livestock exposure pathways are numerous and that microplastic contamination of the food chain is a growing concern.
Interactions and effects of microplastics with heavy metals in aquatic and terrestrial environments
This review explores how microplastics absorb toxic heavy metals from the environment and what happens when organisms ingest these contaminated particles. In the acidic conditions of an animal's digestive system, metals can separate from the plastic and accumulate in body tissues. Since heavy metals can concentrate on microplastics and then transfer up the food chain, this combination poses a compounded health risk to wildlife and potentially to humans who eat contaminated seafood.
Interaction of microplastics with heavy metals in soil: Mechanisms, influencing factors and biological effects
This review summarizes how microplastics and heavy metals interact in soil, where microplastics can absorb and carry toxic metals through the food chain and into the human body. Aging and weathering of microplastics changes their surface properties, making them better at picking up heavy metals, which raises concerns about combined exposure through contaminated crops and water.
Assessment of heavy metal concentration and their relationship in beef sold in markets
A study measured lead, cadmium, and arsenic concentrations in beef muscle, kidney, and liver from markets in Ghana. Heavy metals can adsorb to microplastics in the environment and accumulate in livestock, highlighting pathways through which plastic pollution may contribute to contaminated meat.
Impact of Co-Contaminants (Microplastics and Others) on Heavy Metal/Metalloid Toxicity and Accumulation in Plants
This review examines how microplastics act as co-contaminants alongside heavy metals and metalloids in agricultural soils, influencing their toxicity and uptake by plants. Researchers found that the presence of microplastics can alter how metals like cadmium, arsenic, and lead accumulate in plant tissues, with implications for crop safety and agricultural productivity.
How aging microplastics influence heavy metal environmental fate and bioavailability: A systematic review
This systematic review found that environmental aging (UV, weathering) degrades microplastics into smaller particles with higher surface reactivity, increasing their capacity to adsorb heavy metals. These aged microplastic-heavy metal complexes bioaccumulate through the food chain, posing greater ecological and human health risks than either pollutant alone.
The Unseen Threat of the Synergistic Effects of Microplastics and Heavy Metals in Aquatic Environments: A Critical Review
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 Retrospection on Mercury Contamination, Bioaccumulation, and Toxicity in Diverse Environments: Current Insights and Future Prospects
This review examines mercury contamination in the environment, its accumulation in the food chain, and its toxic effects on living organisms. Mercury exposure through contaminated crops and seafood can cause cancer, genetic damage, and disruption of enzymes and proteins in the body. While focused on mercury rather than microplastics, the research is relevant because microplastics can absorb and transport mercury and other heavy metals into organisms.
Interaction of Microplastics and Heavy Metals on Aquatic Organisms : A Review
This systematic review examines how microplastics interact with heavy metals in waterways, finding that plastic particles absorb toxic metals and then release them inside organisms that ingest them. This combination increases the toxicity of both pollutants, leading to DNA damage, tissue changes, and reproductive problems in aquatic life, with potential consequences for human health through the food chain.
Microplastics as a vehicle of heavy metals in aquatic environments: A review of adsorption factors, mechanisms, and biological effects
This review summarizes how microplastics in water can absorb and carry toxic heavy metals like lead and cadmium, making them more dangerous to aquatic life than either pollutant alone. Environmental factors such as water acidity, salinity, and organic matter influence how much metal sticks to microplastic surfaces. Since contaminated seafood is a major source of human exposure, understanding these interactions is important for assessing health risks.
Coupled effects of microplastics and heavy metals on plants: Uptake, bioaccumulation, and environmental health perspectives
This review examines how microplastics and heavy metals work together to harm plants when both are present in soil. Microplastics can absorb heavy metals like lead, cadmium, and arsenic, and when plants take up these contaminated particles, the combined toxic effect is worse than either pollutant alone. This is concerning for human health because crops grown in contaminated soil could carry both microplastics and concentrated heavy metals into the food supply.
Microplastic-mediated environmental behavior of metal contaminants: mechanism and implication
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.
Particulate plastics as a vector for toxic trace-element uptake by aquatic and terrestrial organisms and human health risk.
This paper reviews evidence that microplastics and nanoplastics act as carriers for toxic trace elements like lead, mercury, and cadmium in both aquatic and terrestrial environments, concentrating these metals on their surfaces. The authors assess how adsorption of heavy metals onto plastic particles may increase human and wildlife exposure risks, and discuss how environmental conditions influence metal uptake by plastics.
