Microplastic Pollution Map
Die Microplastic Pollution Map (MPPM) von oeoo ist eine interaktive Weltkarte, in der wir bereits seit 2013 die Wasserproben in unterschiedlichen Meeresregionen abbilden, die von oeoo gesammelt und im eigenen Labor in Kiel auf ihre chemische Zusammensetzung hin analysiert wurden.
Erstmals steht damit eine interaktive Weltkarte zur Verfügung, auf der Art und Umfang von Verschmutzung der Meere durch Mikroplastik dokumentiert werden. oeoo leistet so seit 2013 einen Beitrag zur Erforschung der mittel- bis langfristigen Auswirkungen des Mikroplastiks auf Mensch und Tier.
One Earth – One Ocean e.V.’s Microplastic Pollution Map is the first interactive world map to document the nature and extent of marine pollution through microplastics.
In order to obtain up-to-date raw data on the pollution levels with microplastic in the waters, water samples of the North Sea, the Atlantic and the Mediterranean are currently being collected regularly. 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, which our partner PHAT Consulting from Hamburg has technically implemented for us. The association is looking for cooperation partners in order to collect data from water samples wherever possible.
Please find enclosed further information about our study results (April 2016).
Our laboratory in Kiel:
The big container vessels of OPDR
The water samples are temporarily stored in a container in the harbour of Hamburg.
The FTIR spectrometer, with which the samples are analysed for their chemical composition
For this purpose, the water is finely filtered so that suspended particles adhere to the filter sample. These ingredients are then analysed so that it can be determined which plastics are in the sample.
The tiny particles are applied to slides and placed in the FTR spectrometer.
Our oeoo laboratory in Kiel with its equipment.
Analysis results from the spectrometer must be interpreted.
Finally, the data is entered into a database and visualised on the Microplastic Pollution Map.
Applications
The Microplastic Pollution Map contains several windows. The chart shows the sample positions for the microplastic examinations. These can be sorted according to different criteria: it is possible to search for sea areas, for more detailed sampling locations, for the years of sampling or also for plastic types. By clicking on the subsegments or by ticking the sampling years, the selection is made.
The corresponding samples are displayed in the nautical chart and the log sheet shows the individual samples and the plastics identified therein.
By pressing the CTRL key, the mouse can be used to make multiple selections within a category (e.g., year of sampling, location of sample, type of plastic).
In the nautical chart, individual sampling locations can also be marked. The corresponding log extracts are then displayed.
