Microplastics in soil: a comprehensive review of analytical techniques
AI summary Read the abstract
This comprehensive review evaluates the various analytical techniques used to identify and quantify microplastics in soil, including sieving, density separation, chemical digestion, and spectroscopic methods like FTIR and Raman spectroscopy. The authors found significant inconsistencies across studies in how soil microplastics are measured, making it difficult to compare results between different research groups. The review calls for standardized protocols to improve the reliability of soil microplastic assessments.
Microplastics (MPs) pollution has increasingly been recognized as a critical environmental issue impacting terrestrial ecosystems, particularly soil matrices. This review comprehensively evaluates existing identification techniques for MPs in soil, highlighting the complexities associated with soil matrices, such as heterogeneity, organic matter content, and diverse particle sizes. Current methods, including sieving, filtration, density separation, chemical digestion, and spectroscopic analysis (e.g., FTIR, Raman spectroscopy), are critically assessed for efficiency, reliability, and applicability. Our analysis identifies significant methodological inconsistencies across studies, emphasizing the urgent need for standardized analytical protocols to enable reliable comparative assessments. Recommendations include the implementation of stringent quality assurance/quality control measures to mitigate cross-contamination and enhance data quality. Given the projected increase in global plastic production and consequent MPs pollution, it is imperative to develop standardized, scalable, and cost-effective methodologies for monitoring MPs in soil environments.

Microplastics in soils: A comparative review on extraction, identification and quantification methods
AI summary Read the abstract
This review compares the various methods scientists use to extract, identify, and measure microplastics in soil, highlighting the strengths and weaknesses of each approach.
