    Description: The anthropogenic affectation was evaluated on the coast N of the Gulf of Batabanó in May 2003 (corresponding to the provinces of Matanzas and Havana), in areas located in the line of the coast. The results were compared with the historical information of the sector. In the coast N and the Ensenada of the Broa, the parameters oxygen saturation, DBO5 and DQO showed characteristic high values of eutrofication. The biggest contribution in the Cianoficies was in the near coastal areas to sources of organic contamination. In the case of the nutrients they show specific data of mesothrofic waters with tendency to the eutrofization and the silts presented a high affectation for toxic metals. The area near to Guanímar is distinguished to present conditions of organic contamination that favor heterothrofic conditions, corroborated by a prevalence of the processes of mineralization of the organic matter over primary production and lows values of fitoplankton concentration. On the contrary, in the region of Surgidero of Batabanó, the processes of synthesis of organic matter prevail suggested by a high primary production, and concentration of fitoplankton, with low breathing levels and mineralization of the organic matter, that indicates that the system is behaving autothrofically. In a general way, this sector is very affected by the anthropogenic impact. The information obtained is of great importance for the development of the fishing and tourist industries in the area.

    Description: This study presents some results of monitoring the beaches at East of Havana City, Cuba, during February and August corresponding to the rainy and less rainy seasons, respectively. For the bacteriological analysis were carried out 5 samplings in a period of 30 days, the rest of the samples was collected as punctual samples. The results are compared with those obtained in other samplings, specifically with 2004 period and with the requirements in the Cuban Standard NC: 22, (1999). Practically, the whole area showed pollution indicators deteriorated, such as: the permanganate oxidability value, bacteriological indicators and hydrocarbons, the last one corresponds to a lightly polluted area by hydrocarbons. The most affected areas were the outlet of the rivers Guanabo and Itabo and the lagoon with the same name, which is not beneficed by the circulation régime and are occasionally affected by waste waters disposal. The comparison with previous years indicate as general way a maintenance or increment in the organic matter, nutrients and dissolved and dispersed hydrocarbons, as well as a slight increase in the coliforms and fecal streptococcus concentrations Rincón de Guanabo area, considered as a protected area by the environmental authorities in Cuba was reported as a lightly contaminated area.
