Figure 10 Activity concentrations of 210Pbtot, 226Ra, 228Ra and 228Th (Bq kg-1 dw) in sectioned (0-1, 1-3 and 3-6 cm) sediment cores from stations HEI07, HEI08, HEI42 and HEI47. Average depths of each section are plotted. It was not possible to determine the activity concentrations of 210 Pb for station HEI47 due to high self-attenuation in the sample, due to presence of elements with high atomic number. Analytical uncertainties are given as ±2σ .
