Abstract In this paper the air pollution data related to SO2 emissions are studied for 14 stations in the city of Montreal for 1975. Some descriptive statistics are computed in order to characterize the overall pollution situation: monthly means of hourly measures, overall monthly means, relative frequencies of daily means and of daily maxima. The seasonal effects can easily be seen. Then some comparative analyses are made in order to study the proximities between the stations: Chernoff's faces, Andrews' graphs, STATIS and arrowhead charts. It is seen that the stations can be separated in three main groups in which different pollution sources can be identified. Finally correlation coefficients are computed for every pair of stations and some interesting comments can be made with respect to the sources of pollution.
