Microplastic Pollution Map is the first interactive world map to document the nature and extent of marine pollution through microplastics. OEOO has been cooperating with the shipping line OPDR from Hamburg since 2013, whose ships sail on fixed routes between Northern Europe and Africa. These samples are analyzed for their chemical composition by OEOO in their own laboratory using a FTIR spectrometer. The results have been incorporated into the oeoo database since 2013 and are available to the public on this interactive world map
