新乡市绿化落叶植物叶片中氯、硫、氟元素背景值初步研究

PRELIMINARY STUDY ON THE BACKGROUND VALUE OF CHLORINE, SULPHUR AND FLUORINE IN THE LEAVES OF DECIDUOUS PLANTS FROM THE XINXIANG'S CITY

分析了河南省新乡市十二种城市绿化落叶植物叶片中的氯、硫、氟的含量，其中氯３．５２３ｍｇ／ｇ，硫３．８７１ｍｇ／ｇ，氟４６．５３３μｇ／ｇ，探讨了这三种元素的背景值水平，该项工作为利用植物监测评价城市大气污染提供了基本参考资料。

In this paper, the contents of the chlorine, sulphur and fluorine in the leaves of 12 deciduous plants from the Xinxiang city of Henan province are reported, there are: chlorine 3.523mg/g, sulphur 3.870mg/g and fluorine 46.533μg/g. The background values of these three elements are discussed, this work has provided a fundamental reference materials for evaluate the city's atmospheric pollution with use of biomonitoring techniques.
