New insights from thermal desorption–gas chromatography–mass spectrometry (TD–GC–MS) data on microplastics in salt samples
Presented at SETAC 15–19 May 2022
The poster entitled “New insights from thermal desorption–gas chromatography–mass spectrometry (TD–GC–MS) data on microplastics in salt samples” was presented by Markes International at the 32nd Annual Meeting of the Society of Environmental Toxicology and Chemistry (SETAC), which was held on 15–19 May 2022 in Copenhagen, Denmark, and online.
Analysis of microplastic contamination in salt
Microplastics – polymer fragments 1 μm to 5 mm in size – can enter the human body from our food and water, and even from the air we breathe. As a result, scientists are focusing on investigating them.
This poster demonstrates how TD–GC–MS was used to identify, characterise and quantify microplastics from salt samples, such as Celtic Sea salt and Himalayan rock salt.
The technique revealed that despite being deposited 50 million years ago, Himalayan rock salt exhibits some traces of microplastic contamination
