Microplastics – Analytical Methods Compared

According to a study to be published in the April 15, 2021 journal, Science of The Total Environment, by researchers with the Ministry of Natural Resources, Qingdao, China “… Microplastics, as an emerging pollutant, are widely spread in the oceans. The sampling method is the most basic and important factor affecting the reported microplastic abundance data. Three sampling methods, most commonly used for microplastic collection, including direct filtration … 20 μm sieve pre-concentration followed by 0.45 μm filtration and Manta trawling with a 150 μm mesh size net were studied.

The results showed that there were orders of magnitude difference in abundance of microplastic across the three methods … The polymer types of microplastic collected … were similar, but polymer proportions were different … Our results suggested that an appropriate method should be selected upon actual sampling condition and available tools during the research process to improve the credibility of the results …” #Microplastics #PlasticWaste #SingleUsePlastic
