Arsenic and antimony distribution in the Ría de Arousa: before and after the Prestige oil tanker sinking

Author affiliations

Abstract

The behaviour of arsenic and antimony in the Ría de Arousa (Galicia, north west of Spain) and the influence of the Prestige accident in the estuary is evaluated. As and Sb were simultaneously determined by HG-ICPOES in seawater samples after a preconcentration with La in a knotted reactor. The highest As concentration is in the inner and middle parts of the ría where the current is weaker and next to the main ports of the area. The largest Sb concentrations were found in the bay of the ría. Linear variation of concentration vs. salinity for As and As/Sb ratios indicated that there was no pollution in the waters of Arousa. The Prestige oil spillage had no serious influence and the values of arsenic (most of them <1.5 μg L−1) are similar to the average oceanic concentration, whereas concentrations for antimony (most of them <0.15 μg L−1) are less than the oceanic ones.
