Microplastic contamination in commercial sea salt of Vietnam

This is the first study which assessed microplastic pollution of sea salt products from Vietnam. The results obtained 9 iodate fine table and 4 raw samples collected different regions in Vietnam showed that were present 100% salts samples. mean concentration was 787±101 items/kg 340±26 for salts, respectively. For both salt, fibers predominant type microplastic, accounted more 60% total particles. In added, three types polymer detected 12 particles by FTIR, including polyethylene (PE), polypropylene (PP) polystyrene, which, most common PE (accounted 67%). With a daily consumption 5-10g/day, annual number ingested per Vietnamese adult varies 637 to 1241 alone.
