Abstract

Surface marine sediments proceeding from two Galician Rías (NW Spain) and the coast of Dakar (Senegal) were analyzed by cold vapor atomic absorption spectrometry (CV-AAS) in order to evaluate the distribution of inorganic and total mercury as well as to compare the pollution levels in both aquatic systems. The accumulation of mercury in Galician sediments (values < 0.12 μg/g) was considerably higher than that found in sediments from the Dakar coast (values < 0.025 μg/g). Nevertheless, all the samples studied can be considered unpolluted on mercury according to the quality criteria (values < 0.05 μg/g) used for the classification of sediments. A similar distribution was observed for inorganic and total mercury, with ratios inorganic mercury/total mercury ranging from 97.1 to 99.8 %, indicates that inorganic mercury is the main specie of mercury in all samples studied. Two latent variables, explaining the 99.11 % of the initial variance, were extracted from the data using principal component analysis. This allowed sediments to be grouped in two different subgroups according to their similar behaviour.
