A study “Global Pattern of Microplastics (MPs) in Commercial Food-Grade Salts: Sea Salt as an Indicator of Seawater MP Pollution” co-designed by Professor Kim, Seung-Kyu at Incheon University and Greenpeace East Asia found positive correlations between microplastics in seawater and microplastics in sea salts which people consume everyday. It is a global pattern that the sea salt containing higher microplastic numbers were mostly located at coasts polluted by microplastics. Greenpeace is urging corporations around the world to reduce and eventually phase out single-use plastics.
