Microplastics as Source or Sink of Potentially Toxic Elements: Dynamics in the Soil-Plant System
AI summary Read the abstract
This review paper summarizes research on how tiny plastic particles in soil can either trap or release toxic metals and chemicals. These microplastics can act like sponges that soak up harmful substances, making them less dangerous, or they can break down and release toxins that plants might absorb. This matters because these toxic substances could eventually end up in our food supply when crops grow in contaminated soil.
Soil is among the environmental compartments increasingly affected by microplastics (MPs) contamination, mainly coming from industrial activities, agricultural practices, atmospheric or waterborne transport, and improper waste disposal. Despite the increasing attention to the fate of MPs in soil over the last years, research in this area is still limited compared to aquatic ecosystems. The introduction of MPs into the soil environment can modify both the soil properties and the interactions among soil components, plants and microorganisms, thus affecting also the mobility and availability of other contaminants, such as potentially toxic elements (PTEs). This review critically examines the complex dynamics between MPs and PTEs in the soil ecosystem, in particular in agricultural soils, and the conditions under which MPs can act as a source or a sink of PTEs. Indeed, microplastics can adsorb or complex PTEs on their surfaces, thus reducing their mobility and availability, or release/mobilize PTEs after their degradation or as micro/nano-vectors of PTEs. Understanding such mechanisms is relevant to evaluating the environmental risks associated with the co-presence of MPs and PTEs in soil, a situation very likely to occur in most contaminated sites as well as in soils strongly affected by anthropogenic activities.

Microplastics as Source or Sink of Potentially Toxic Elements: Dynamics in the Soil–Plant System
AI summary Read the abstract
Tiny plastic bits in soil don't just sit there—they can either trap toxic metals (like lead or cadmium) and keep them away from plants, or release and carry those metals deeper into the soil and into crops, depending on conditions. This matters because the food we grow may be affected by this hidden interaction between plastic pollution and toxic metals in farmland, though scientists are still working out exactly when microplastics make things better or worse. This paper reviews existing research on the topic rather than presenting new experimental findings.
Microplastics-Mediated Behavior of Potentially Toxic Elements in Plant–Soil Systems: Adsorption, Bioavailability, and Phytotoxicity
AI summary Read the abstract
Microplastics in soil don't just sit there, this review of existing research shows they can either trap toxic metals (like cadmium and arsenic) or make them easier for crops to absorb, depending on conditions like soil type and plastic particle size. In some cases, this combo can shrink crop growth by up to 30%, which matters because these are the same toxic metals that can end up in the food we eat, potentially raising long-term health risks.
The role of microplastic pollution in the modification of the physicochemical properties of arable soil and uptake of potential toxic elements by plants
AI summary Read the abstract
Researchers conducted a series of studies analyzing how microplastic pollution modifies the physicochemical properties of arable soil and affects the uptake of potentially toxic heavy metals by plants, beginning with a comprehensive literature review of microplastic interactions with plant physiology, metals, pesticides, and pathogens.
Impacts of microplastics on terrestrial plants: A critical review
AI summary Read the abstract
This review examines how microplastics affect land-based plants, finding that they can alter soil structure, disrupt beneficial soil microbes, and reduce plant growth. Microplastics also carry toxic chemicals like plasticizers and heavy metals that can be taken up by plant roots and enter the food chain. The findings raise concerns about human health since contaminated crops could be a hidden source of microplastic and chemical exposure in our diets.
Influencing mechanisms of microplastics existence on soil heavy metals accumulated by plants
AI summary Read the abstract
This review summarizes existing research on how microplastics in soil affect the uptake of heavy metals by plants. Microplastics can change soil chemistry and microbial communities in ways that alter how much toxic metals plants absorb through their roots. This is concerning for human health because microplastic-contaminated agricultural soil could lead to crops that contain higher levels of dangerous heavy metals.
