Resumen:
Heavy metals occur in the environment both as a result of natural processes and as pollutants from human activities. Contamination of the marine environments, such as estuaries, has risen in recent years as consequence to the population increase as well as the harbor activities and industrial development. The estuarine systems have particular hidrogeochemistry characteristics. They are highly productive and sensitive areas and are seriously affected by different sources of pollution. The estuary burden of heavy metals is actually a serious environmental concern and public interest regarding this topic has been increasing. The effluent discharges may be the main sources that cause effects of impact by heavy metals in the sediment. The studies about presence of Cu in the sediment and water from Bahía Blanca estuary have beginning at earlier of 1970 and a monitoring program comes from since 2002. Copper deserves to be mentioned between one of the most important essential trace element for plants and animals. Besides, it can be chosen as a general indicator of industrial and domestic pollution. Bahía Blanca Estuary wetlands are located in the northern limits of Patagonia and they are one of the largest coastal systems in Argentina. The medium and inner area of the estuary is an environment with an extensive human population, many ports, industries, textile plants, fish and meat factories, silos, and cereal mills. The OBJECTIVE of this work was to evaluate the temporal and spatial copper distribution in the bottom sediments and dissolved within the water from the inner part of the estuary.
