This study describes a new method of quantifying different types of microplastics in environmental samples using FTIR imaging. The method utilized was able to successfully recover, identify, and quantify microplastics in organic-rich samples such as sediment, water, and fish.
The method utilized FTIR imaging, combined with the MPhunter software and proved to be a rapid and accurate way to automatically identify and quantify microplastics and other materials. Combined with H2O2 oxidation, FTIR imaging is a strong candidate to be a standard method in microplastic analysis, allowing further study and understanding of microplastics in the environment
