Abstract:

The aim was to study the influence of fluoride from air pollution on the plants and soils. Fluorine contents in plants and soils in Kaili area were monitored by a fluoride ion selective electrode method and its characteristics were discussed. The results showed that fluorine contents of plants and soils in this area with an average of 513.99 μg/g and 279.60 μg/g, ranged from 135.62-1420.97 μg/g and 240.50-340.36 μg/g, respectively. The fluorine contents of plants and soils are both higher than the background values in plants and soils and the plants and soils were polluted. The fluorine contents differed greatly in different species. Camellia olelfera Abel had the highest value while Pinus massoniana Lamb. had the lowest value. There was greater difference among different type plants. The fluorine content of different type plants was as follows: shrub> vine> herb> tree and evergreen plant> deciduous plant. The fluorine content of plant and soil in different sites was different. Some plants had obvious difference in its fluorine contents, while some plants did not.
