Short-term variations in trace metal concentrations in the baltic

Baltic surface water was sampled at a fixed position at intervals of a few hours. The trace metal concentrations were measured by graphite furnace AAS after extraction. The mean concentrations found were (ng l −1): Cd, 30 ± 2.7; Cu, 800 ± 48; Fe, 358 ± 165; Ni, 820 ± 49; Pb, 16 ± 4.5; Zn, 900 ± 160....

Description
Summary:Baltic surface water was sampled at a fixed position at intervals of a few hours. The trace metal concentrations were measured by graphite furnace AAS after extraction. The mean concentrations found were (ng l −1): Cd, 30 ± 2.7; Cu, 800 ± 48; Fe, 358 ± 165; Ni, 820 ± 49; Pb, 16 ± 4.5; Zn, 900 ± 160. The variability in the trace metal concentrations is of the same order of magnitude as the precision of the method. Thus, no spatial variations in trace metal concentrations were found.
