Intercomparison of sediment sampling techniques by means of radionuclide and heavy metal analysis
Four different sediment samplers were applied several times in the western Baltic Sea at a position with soft, muddy sediment. The artificial radioisotopes137Cs and134Cs, exhibiting a characteristic vertical profile in the cores, were determined from vertical slices of the different cores by the laboratories participating.
In order to avoid analytical differences between the laboratories merely due to calibration errors, one bulk sample of about 8.5 kg dry weight was collected from the surface, homogenized and analysed by laboratories outside this experiment. This sample is regarded as the “standard” sample, which all results from the sediment corers are referred to.
Artificial and natural radionuclides such as40K,134Cs,137Cs,106Ru,125Sb,239, 240Pu,238Pu,241Am,210Pb,210Po,226Ra,238U, and232Th were determined in this sample. The methods and results of the analyses are discussed. The comparison of the sediment corers are complemented by the determination of the metals Mn, Zn, Cu, and Pb in vertical slices.
