Atmospheric pollution in the Venice area I. Sulphur dioxide, suspended particles and sulphates.

The results of 2 years monitoring of sulphur dioxide, suspended particles and sulphates at three different sites (an industrial zone on the mainland, an urban zone on the mainland and an urban insular zone) in the Venice area are presented. The 24-h mean concentrations of the three pollutants fit a lognormal distribution, the parameters of which are estimated. The zero-order correlation coefficients between the concentrations of the three pollutants are determined: they are very high in the insular zone of Venice and lower in the industrial and urban zones of the mainland.
