Application of Infrared and Near-Infrared Microspectroscopy to Microplastic Human Exposure Measurements
AI summary Read the abstract
This review evaluates how infrared and near-infrared microscopy techniques are being used to measure human exposure to microplastics from drinking water, dust, food, and air. Researchers found that while these spectroscopic tools are powerful for identifying plastic types and sizes, significant challenges remain in standardizing methods across different sample types. The study highlights that consistent, reliable exposure measurements are essential for understanding whether microplastic levels in everyday environments pose meaningful health risks.
Microplastic pollution is a global issue for the environment and human health. The potential for human exposure to microplastic through drinking water, dust, food, and air raises concern, since experimental in vitro and in vivo toxicology studies suggest there is a level of hazard associated with high microplastic concentrations. However, to infer the likelihood of hazards manifesting in the human population, a robust understanding of exposure concentrations is needed. Infrared and near-infrared microspectroscopies have routinely been used to analyze microplastic in different exposure matrices (air, dust, food, and water), with technological advances coupling multivariate and machine learning algorithms to spectral data. This focal point article will highlight the application of infrared and Raman modes of spectroscopy to detect, characterize, and quantify microplastic particles, with a focus on human exposure to microplastic. Methodologies and state-of-the-art approaches will be reported and potential confounding variables and challenges in microplastic analysis discussed. The article provides an up-to-date review of the literature on microplastic exposure measurement using (near) infrared spectroscopies as an analytical tool, highlighting the recent advances in this rapidly advancing field.
