Abstract:Sulfur dioxide concentration, sulfation rate and fluoride contents in atmosphere around the Nanshan district in Shenzhen were measured in summer and winter of 2000 using two different sampling methods (i.e. conventional standard sampling and static suspending piece absorption). At the same time, sulfur and fluorine contents in plant leaves were also measured. Regression analysis showed that pollutant concentrations in atmosphere were significantly correlated with the pollutant contents (x) in plant leaves. On the basis of these correlations, biomonitoring mathematical models for evaluation on air sulfation rate (y) were developed as y=0.781x-0.754 for summer and y=l.88x-2.283 for winter, whereas on air fluoride (y), y=0.363x-7.511 for summer and y=0.175x-3.461 for winter. It is suggested that the models are reliable.
