Resumen:
Bahía Blanca is an estuarine environment with a very particular behavior, which includes a large tidal plain with an area close to 1150 km2, a relatively small input of inland water, and with several marginal areas that seasonally function as hypersaline. Mud is predominant in the sediments, where a significant population of the crab Chasmagnathus granulata lives during the whole year. There are several cities along the estuary as well as important harbors and a large industrial nucleus which discharge their effluents within this environment. Cu and Zn concentrations were determined in samples of water (for both dissolved and suspended particulate matter) and surface sediments (total and
