热电厂附近大气、树叶和土壤中氟含量的关系研究

Research on Fluorine Contents in Air,Soil and Tree Leaves Around Hot Power Plant

通过分析湖北省荆州市沙市热电厂附近不同采样点大气、土壤和不同树种叶片的含氟量,研究了大气、土壤含氟量与植物叶片含氟量间的关系,探讨了氟污染的来源及转化。结果表明:沙市热电厂周围存在一定程度的氟污染,主要来源于热电厂废气排放和煤灰飘散;不同距离、不同树种叶片含氟量有明显的差异,叶片氟积累量与大气中氟含量呈显著正相关。

Fluoride contents were analyzed in air,soil and leaves of different species by Shashi Hot Power Plant in Jingzhou of Hubei Provirce.The correlations of fluoride con- tent between air,soil and leaves were analyzed and the source and transformation of fluo- rine pollution were discussed.The results showed that Shashi Hot Power Plant was a certain external fluorine pollution resource.The primary source was exhaust gas and coal ash.Fluoride content in leaves of different species had obvious difference.The increase of fluorine proportion accumulation in leaves have obvious relation with fluorine concentra- tion in atmosphere.
