Abstract: Fumigation and exposure experiments show that for monitoring atmospheric SO2, pollution. visible injured symptoms of Viola faba leaf is not a profitable indicator, but its superoxide dismutase(SOD) activity, ascorbic acid(ASA) content, amino acid(AA) content, peroxidase(POD) activity and chlorophyll content are good indicators, among which, SOD activity is the best one. Using these five indicators to make an integral assessment will be better than using each of them.

Key words: Biomonitoring, Sulfure dioxide, Vicia faba
