“…Significant amounts of MPs are generated in landfills, peri-road areas, and agricultural areas [ 186 , 187 ]. Soil contamination can come from many sources, including compost [ 147 ], mulch film [ 188 ], greenhouse materials, irrigation tools [ 189 ], plant protection products, fertilizers [ 190 ], municipal solid waste, sewage treatment plants [ 191 ], used tires [ 119 , 164 ], and precipitation [ 192 ]. The presence of plastic particles in soils from China [ 193 , 194 , 195 ], Iran [ 196 ], Brazil [ 197 ], and Spain [ 198 ] was confirmed.…”

Plastics are commonly used for packaging in the food industry. The most popular thermoplastic materials that have found such applications are polyethylene (PE), polypropylene (PP), poly(ethylene terephthalate) (PET), and polystyrene (PS). Unfortunately, most plastic packaging is disposable. As a consequence, significant amounts of waste are generated, entering the environment, and undergoing degradation processes. They can occur under the influence of mechanical forces, temperature, light, chemical, and biological factors. These factors can present synergistic or antagonistic effects. As a result of their action, microplastics are formed, which can undergo further fragmentation and decomposition into small-molecule compounds. During the degradation process, various additives used at the plastics’ processing stage can also be released. Both microplastics and additives can negatively affect human and animal health. Determination of the negative consequences of microplastics on the environment and health is not possible without knowing the course of degradation processes of packaging waste and their products. In this article, we present the sources of microplastics, the causes and places of their formation, the transport of such particles, the degradation of plastics most often used in the production of packaging for food storage, the factors affecting the said process, and its effects.

“…Agricultural films and compost applications are the most likely important sources of MPs in soil among the previous sources [1,41]. Thus, generally, the source of MPs in terrestrial environments can be classified into two groups: (1) point sources (such as plastic factories, landfills, and wastewater treatment plants) and (2) non-point sources (such as roads and agricultural lands) [42] (Figure 2). sources [1,41].…”

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.

“…MNPs from agricultural practices Agricultural practices contribute to the majority of MNPs in farming soils. Primary MNPs enter soils through the use of plastic-encapsulated slow-release fertilizers, pesticides, and seed coatings, as these remain in the soil after releasing the active ingredient [45,46]. Irrigation with MNP-contaminated wastewater and the use of waste sludge containing plastic fragments for compost also contribute to the MNPs in the soil.…”

Plastics, due to their varied properties, find use in different sectors such as agriculture, packaging, pharmaceuticals, textiles, and construction, to mention a few. Excessive use of plastics results in a lot of plastic waste buildup. Poorly managed plastic waste (as shown by heaps of plastic waste on dumpsites, in free spaces, along roads, and in marine systems) and the plastic in landfills, are just a fraction of the plastic waste in the environment. A complete picture should include the micro and nano-plastics (MNPs) in the hydrosphere, biosphere, lithosphere, and atmosphere, as the current extreme weather conditions (which are effects of climate change), wear and tear, and other factors promote MNP formation. MNPs pose a threat to the environment more than their pristine counterparts. This review highlights the entry and occurrence of primary and secondary MNPs in the soil, water and air, together with their aging. Furthermore, the uptake and internalization, by plants, animals, and humans are discussed, together with their toxicity effects. Finally, the future perspective and conclusion are given. The material utilized in this work was acquired from published articles and the internet using keywords such as plastic waste, degradation, microplastic, aging, internalization, and toxicity.
