Description
Summary:The Bahía Blanca Estuary includes a large tidal plain with an area close to 1150 km2. Mud is predominant in its sediments, where a significant population of the crab Chasmagnathus granulata lives during the whole year. Moreover, there are important urban and industrial discharges into this environment. Cd and Pb concentrations were determined in samples of water (for both dissolved and suspended particulate matter) and surface sediments (total and 63 µm fractions). Organic matter was analysed in the sediments, while temperature, salinity, pH and dissolved oxygen were measured in the estuarine water. The metal concentrations determined in this study were: 1.47 ± 1.08 µg Cd g-1 and 14.68 ± 4.31 µg Pb g-1 in surface sediments; 2.21 ± 1.33 µg Cd g-1 and 25.70 ± 7.09 µg Pb g-1 in the
