Abstract

This research work deals with monitoring of the water off the construction area of the Pecém harbor, Ceará State, Brazil and its influence zone, carried out in 1998. Data on such hydrological parameters as temperature and salinity indicate a slight trend of vertical variation, what is a clear sign of the environmental homogeneity of the studied region. The surface values of dissolved oxygen varied within the saturation limits, but with a downward trend with depth. pH values were in the range of 7.94 – 8.54 (alkaline), indicating the absence of acid substances. Waters have low transparency and high index of light extinction on account of a high content of solids in suspension, but no oils or grease were detected. Contamination by fecal coliforms was practically non existent.
