“…Microplastics can also act as carriers of organic and inorganic contaminants present in water (Zhou et al, 2020;Abbasi et al, 2020; and could cause enhanced exposure to these. Microplastics, depending on their size, are also excreted (Xu et al, 2020) and then they do not exert apparent impact on amphipods or plants (Fang et al, 2021). The microplastics accumulated in organs of aquatic species (i.e.…”

“…MP pollution in soil has attracted minimal scientific attention compared to that in the marine environments, despite the fact that it has recently been documented that soil is a major sink of MPs (4-23 times larger in its mass than marine environments) [5,25,32,33]. Microplastics have been found in soils all over the world, including Asia, Europe, North America, Africa, and Oceania, with abundances ranging from 870 particles kg −1 in home garden soil to 42,960 particles kg −1 in farmed regions.…”

“…The sources of MPs in soil include landfills, inorganic fertilizers and organic waste application (such as sewage sludge and compost) that are contaminated by plastics, irrigation by wastewater, irrigation pipes, wastewater treatment plants, agricultural usage of plastic films (such as plastic mulch (broadly used to improve water use efficiency and plant growth) and greenhouse coverings), packaging bags, plastic-coated fertilizers, fertilizer/seed containers, textile applications, industrial waste, road dust, and dispersed atmospheric depositions of fibers and fragments [1,3,25,32,33,[35][36][37][38][39]. As well, irrigation water and other diffuse sources can all introduce plastic into agricultural soils [35].…”

Microplastic (MP) pollution is a widespread global environmental concern, representing an emerging contaminant with major implications for ecosystems and human well-being. While extensive research has focused on MPs in aquatic environments, their impact on sediments and soils remains inadequately explored. Studies have confirmed the harmful effects of MPs on soil and sediment biota, as well as on the properties of these ecosystems. Furthermore, the long-term persistence of MPs within the environment contributes to their accumulation in terrestrial and marine food chains, with potential consequences for groundwater quality. Although several methods have been applied to mitigate MP pollution, some methods have drawbacks and some are not studied well, necessitating the urgent exploration of novel, sustainable, and eco-friendly approaches. Biochar is a remarkable solution for pollution removal; recently it has been used in addressing the increasingly concerning issue of microplastic contamination. This review aims to shed light on the difficulty posed by MPs in soils and sediments, while highlighting the remediation methods and the potential advantages of utilizing BC as an environmentally friendly solution for MP removal and remediation.

“…Preliminary studies have revealed that the presence of MPs in the soil affects bacterial and fungal diversity, besides the reduction of soil enzymatic activities involved in nutrient cycling [10,26,27]. Changes in nutrient cycling-associated microbial enzymes, including β-glucosidase, phosphatase, and urease, can subsequently distress the uptake of substances by plant roots [33,34]. For example, the significant impacts of MPs have been reported on studied soil flora and fauna, including Eisenia fetida, Folsomia candida, Lumbricus terrestris, Triticum aestivum, and Allium fistulosum, thereby altering the soil diversity (Table 1).…”

Microplastics can also directly impact the physiology and metabolism of soil microorganisms by causing oxidative stress and DNA damage in bacteria, which results in cell death and influences microbial activity [27,33]. These alterations also deliver feedback to the microbial environment and affect rhizospheres such as rhizobia and mycorrhiza fungi [26,27,35,36].…”

The production and disposal of plastics have become significant concerns for the sustainability of the planet. During the past 75 years, around 80% of plastic waste has either ended up in landfills or been released into the environment. Plastic debris released into the environment breaks down into smaller particles through fragmentation, weathering, and other disintegration processes, generating microplastics (plastic particles ≤ 5 mm in size). Although marine and aquatic ecosystems have been the primary focus of microplastic pollution research, a growing body of evidence suggests that terrestrial ecosystems are equally at risk. Microplastic contamination has been reported in various terrestrial environments from several sources such as plastics mulch, pharmaceuticals and cosmetics, tire abrasions (tire wear particles), textiles industries (microfibers), sewage sludge, and plastic dumping. Recent studies suggest that the soil has become a significant sink for pollutants released into terrestrial ecosystems and is often contaminated with a mixture of organic and inorganic pollutants. This has gradually caused adverse impacts on soil health and fertility by affecting soil pH, porosity, water-holding capacity, and soil microbial enzymatic activities. Microplastics can interact with the co-existing pollutants of the environments by adsorbing the contaminants onto their surfaces through various intermolecular forces, including electrostatic, hydrophobic, non-covalent, partition effects, van der Waals forces, and microporous filling mechanisms. This subsequently delays the degradation process of existing contaminants, thereby affecting the soil and various ecological activities of the ecosystem. Thus, the present article aims to elucidate the deleterious impact of microplastics and their interactions with other pollutants in the terrestrial ecosystem. This review also addresses the impact of microplastics in disrupting the soil sustainability of the planet.
