Abstract
A method of quantifying microplastic mass in a sample composition, including the steps of pre-treating the sample composition to remove non-microplastic organic matter and extract microplastics thereby providing a pre-treated sample composition, measuring the organic carbon content of a microplastic polymer in the pre-treated sample composition using total organic carbon (TOC) analysis, and quantifying the microplastic mass in the sample composition according to the organic carbon content of the microplastic polymer.

A method of quantifying a total microplastic mass in a sample composition, the method comprising:
- providing a treated sample composition by removing non-microplastic organic matter from the sample composition and by extracting a microplastic polymer having an organic carbon content from the sample composition,
- measuring the organic carbon content of the extracted microplastic polymer in the treated sample composition by using total organic carbon (TOC) analysis, and
- quantifying the total microplastic mass in the sample composition based on the measured organic carbon content of the extracted microplastic polymer.
