Micro Plastics Extraction Techniques in Sediments – A Review
Keywords:Microplastics, Monitoring, Extraction Methods, Sediments
The contamination of micro plastics in environmental matrices has been reported worldwide, and the search for an extraction method is relatively recent. Sediments are considered its greatest receptor, posing a significant challenge among environmental matrices for the extraction of these pollutants. The physicochemical complexity of the sediments challenges the standardization of techniques for micro plastic extraction, making their studies more intricate, requiring more in-depth investigation. Currently, there are ongoing discussions regarding existing research gaps, and a lack of standardized techniques persists in the assessment of the presence of micro plastics in sediment samples. In this work, we conducted a study review to describe different extraction methods and highlight the advantages and disadvantages of each process, considering various salts and oils used in micro plastic extraction techniques from sediments. At the end of the study, we identified some promising methods to be used in micro plastic monitoring programs in sediments that can be replicated in laboratories at a low cost and with easy execution.
