Previous studies have reported high concentrations of atmospheric pollutants in the Municipality of Centro Habana, Havana city, associated with a high risk of respiratory and allergic diseases. A descriptive study was carried out to describe the atmospheric contamination in Centro Habana from October 2001 to October 2003. The study includes the daily concentrations of dioxide of sulfur (SO₂), nitrogen dioxide (NO₂) and acidity index. The statistical analysis includes the central trend, percentages of transgression of the acceptable maximum concentrations (CMA), maxima value and percentiles 25, 75 and 95. The correlation was evaluated among pollutants by means of the coefficient rho of Spearman. Models of multiple lineal regression were built for each pollutant and the selected meteorological variables. The middle concentrations daily of acidity, SO₂ and NO₂ were inferior to the CMA. Moderate direct correlations were observed among all the pollutants, stronger between the SO₂ and the acidity.

Keywords : Atmospheric contamination; NO₂; SO₂.
