【摘要】 为探索大气氟污染与植物叶片含氟量的关系 ,利用氟离子电极法 ,对河北农业大学林学院区域内的树种叶片含氟量进行了 2a的监测 ,同步监测了大气、土壤、水体的氟污染状况 ,进行了相关性分析。结果证明 :林学院区域内有严重的氟污染 ,不同树种叶片含氟量有明显区别 ,树木叶片积累氟含量与大气氟浓度呈显著的正相关。并建立回归方程 ,通过叶氟量监测大气的氟污染状况更多还原

【Abstract】 With fluorin ion electrode the fluorine content in leaves of four tree species was measured. The fluorine pollution in air, soil and water was also measured simultaneously. The relationship between the leaf fluorine content and fluorine pollution in the environment was analyzed. The results showed that the fluorine pollution was serious in the area monitored and fluorine content in the leaves of four tree species was significantly different from each other . There was a remarkable positive correlation between fluorine accumulation in the leaves and fluorine concentration in the air. A regression equation was set up and fluorine pollution can be monitored through the measurement of fluorine content in the leaves.更多还原
