Standardization of FTIR-Based Methodologies for Microplastics Detection in Drinking Water: A Meta-Analysis Indeed and Practical Approach
Summary
This meta-analysis works toward standardizing the methods scientists use to detect microplastics in drinking water using infrared spectroscopy. Consistent detection methods are essential because without them, we cannot accurately compare contamination levels across studies or reliably assess how much microplastic people are actually consuming in their tap and bottled water.
The detection of microplastics (MPs) in drinking water presents significant environmental and public health challenges. This study comprises two stages: a meta-analysis aimed at standardizing Fourier Transform Infrared Spectroscopy (FTIR) methods for MP detection, followed by the practical implementation of these findings in the laboratory. The review of studies conducted from 2019 to 2023 identifies 0.45 μm cellulose nitrate filters and Nile red staining as the most effective techniques for fluorescent detection. Experimental results demonstrate the superior retention capabilities of cellulose nitrate filters and the uniformity of Nile red staining. This dual approach not only optimizes water treatment processes but also enhances the accuracy of MP detection. The findings contribute to improved water quality management and public health protection by establishing robust protocols for MP analysis.
