Résumé du colloque

The corticolous epiphytes were studied in the area of Wawa, Ont. where the atmosphere is polluted by sulfur dioxide, emitting from an iron-sintering plant. An inventory of the epiphytic flora for the region was made and the distribution of SO2 in the area, as well as the pH and sulfate content of water, soil and vegetation were determined. The fallout pattern of SO2 and the chemical indices (ph and SO4 --) of water and soil were correlated with the epiphytic flora of the region in order to find species which can serve as biological indicators of SO2- pollution.
