Abstract

The chemical quality of water and sediment was analyzed in some bays of Sabana-Camaguey Archipelago (SCA). This analysis was done using the existing information that covers from 1976 to 2011. In the rainy one there was oxygen sub-saturation in the bays of West Santa Clara, East Santa Clara, Puerto de Sagua and Los Perros. The nature of organic matter was quite complex and BOD5 and COD values greater than 2 mg · L-1 prevailed. The ammonia concentrations were between 2 and 5 µmol · L-1, and organic nitrogen represented 90 % of total nitrogen. Phosphorus in water was not very abundant, it acted as limiting nutrient for primary producers. Sediments were characterized by significant amounts of organic carbon and low content of organic nitrogen. The bays of Cardenas, San Juan de los Remedios, Buenavista and Los Perros, were impacts of heavy metals.
Keywords:bay, organic matter, nitrogen, phosphorus and quality.
