Abstract:
In order to study the indicating effect of tree leaves’ magnetic properties on atmospheric environment pollution, magnetic parameters were measured on the poplar tree leaves collected from the downtown of Fengyang County, Anhui Province, cement plant and quartz sand plant of Fengyang, and ginkgo tree leaves and phoenix tree leaves grown in the downtown of Fengyang County. Results showed that the main magnetic mineral in tree leaves was magnetite, and its particle was coarse; the magnetic mineral content of poplar tree leaves in different environment was not the same, ranking from high to low as cement plant, Fengyang County and quartz sand plant, which indicated that the degree of atmospheric environment pollution in cement plant was more serious than than in the other two sites. Further analysis suggested the magnetic mineral contents of poplar tree leaves, ginkgo tree leaves and phoenix tree leaves collected from the downtown of Fengyang County differed from one another, and that of ginkgo tree leaves was higher than those of the other two. Thus, using magnetic parameters of tree leaves can monitor the atmospheric environment pollution, while the indication effect of different species leaves exists difference.
Key words: tree leaf, magnetic property, atmospheric environment pollution
