Quantification and Ecotoxicological Evolution of Microplastics in Soil Ecosystem

Plastic debris is ubiquitous in aquatic habitats which elevates the concern about their handiness and hazardous effects on the aquatic environment. The disintegration of larger plastic polymers fabricates the majority of MPs in the form of fiber, pellet, film, and fragments. Human’s everyday usage of plastic sets pressure on rivers and coastal regions, resulting in a contamination load to aquatic ecosystems, which has serious health consequences for both human and aquatic life. Therefore, it’s essential to create and improve methods for identifying and evaluating soil micro-plastics. Density separation is an excellent method for separating soil micro-plastics; likewise, different digestion methods might produce varying degrees of harm, micro-plastics may not be given the credit they deserve. For visual analysis, optical and electron microscopy yields effective results. For spectrum research, infrared and Raman spectroscopy, μ-FTIR, EDS, TOF-SIMS, MALDI-TOF-MS, and ICP-MS, are used in combination with fewer pretreatment steps for efficacy optimization and digesting processes. The innovation of methods for multispectral imaging combined with autonomous data processing can minimize the time and effort needed for the assessment procedure. The technological and methodological requirements of soil micro-plastic examination should be defined and modified based on comparative examinations of different laboratory facilities in order to maximize the accuracy, consistency, and viability of examining data across locations. Therefore, it is essential to investigate less expensive, faster methods of extraction and separation that preserve the characteristics of micro-plastics.
