摘要
对深圳市南山区大气二氧化硫和氟化物污染及当地荔枝叶片含硫量和含氟量进行了为期一年的研究 ,发现荔枝叶片含硫量和含氟量与对应的大气硫化物和氟化物浓度均呈极显著正相关 (p <0 .0 1)。在此基础上根据荔枝叶片含硫量和含氟量 ,对南山区大气二氧化硫和氟化物的污染现状作出了植物学评价 :南山区大气二氧化硫均属轻度污染 ,氟化物则有 73%的区域属III级重度污染区。这种植物学评价结果与大气监测结果是一致的。
This paper is based on a one-year survey of SO 2 /fluorid pollution in atmosphere and fluorid/sulfid content in local lychee leaves in Nanshan District, Shenzhen City.It was found that fluorid/sulfid content in lychee leaves was in significant positive correlation with corresponding fluorid/sulfid concentration in atmosphere (p<0.01). A botanical evaluation on the current state of fluorid/sulfid pollution in this district based on fluorid/sulfid content in local lychee leaves showed that sulfur dioxide pollution was classified as minor pollution level while the fluorid covering 73% section out of this district was as severe level. The botanical evaluation result was in accordance with atmosphere monitoring results.
