Results of German MORS monitoring in 2014 and 2015 (seawater and sediment)

Stefanie Schmied, HELCOM MORS EG 6-2016, 24-26 May 2016, Uppsala, Sweden

Seawater results: Cs-137

Federal Maritime and Hydrographic Agency (BSH) 2

Activity concentrations of 137Cs in surface and bottom waters (marked in red) of the Western Baltic in 2015

Seawater results: Sr-90

Federal Maritime and Hydrographic Agency (BSH) 3

Activity concentrations of 90Sr in surface and bottom waters (marked in purple) of the Western Baltic in 2015

Sediment results: Inventory of Cs-137

Verification of homogeneity: sampling round and round for ten seconds, respectively

Notes

Federal Maritime and Hydrographic Agency (BSH) 6

• Tritium: sampling successful in 2015, measurements still pending (problems with the low level scintillation counter)
• KNiFC-PAN (potassium nickel hexacyanoferrate(II) based on polyacrylnitrile):

another adsorption material for cesium isotopes usage equal to KCFC (potassium cyanocobalt(II)ferrate(II)) previous tests promising, still performing further tests publication of the results is planned for mid 2017
