By means of a 50-day random sampling, from October 1981 to January 1982, in 30-minute consecutive samples, from 4.00 A.M. and 10.00 A.M., the environment-time behavior of smoke and sulphur dioxide in the atmosphere in Centro Habana was studied. A remarkable intermediate variability with prevalence of the ascending trend and a fine oscillatory structure is found. The absolute concentrations values for the two pollutants were lower than those referred to as harmful for short exposure periods.
