An overview of the potential risks, sources, and analytical methods for microplastics in soil

Abstract

<abstract> <p>Contaminants from microplastics in the soil can pose a huge and potential risk to global ecological systems. Microplastic contaminants have become an issue since the source and potential risks have gained a point of great concern. This problem is due to the lack of a comprehensive and systematic analysis system for microplastics. Thus, a comprehensive review of microplastic knowledge is carried out to detect its potential risks, occurrences, sources, and characteristics. The study results show that microplastics have been found everywhere, as shown in the global matrix. However, with the advancement of increasingly sophisticated technology, the microplastics found in the soil can be reduced. The difficulties of analytical systems inherent in particles in even complex matrices can be overcome with technology. Research on the distribution and emergence of microplastics is still very slow in several countries, including Indonesia, the United States, and Africa. The composition and characteristics of microplastics in soil and the environment shows their consistency still indicates a change in source. Microplastics in the soil have extensive and diverse sources, leading to high accumulation. This study also discusses the potential risks and effects of microplastics on soil ecosystems. The interaction and combination of contaminants from adsorbed microplastics can lead to soil fertility and migration systems in the food chain. The impact of microplastics on soil depends on chemical components, natural factors, and morphology. Thus, regional quantification and estimation of emissions from microplastics have a huge gap. In addition, the concentration of microplastics and the masking of microplastics to store carbon in the soil can be influenced by natural factors and require various efforts.</p> </abstract>
