Identification and quantification of microplastics in table sea salts using micro-NIR imaging methods
Summary
Near-infrared imaging was used to detect and count microplastics in table sea salt samples, providing a faster and more accurate method than visual sorting. Sea salt is a well-documented source of human microplastic ingestion, and better detection methods help quantify this exposure.
A method for the identification and quantification of microplastics in table sea salts. The method meets the need for detecting and automatic counting microplastics simultaneously.
