【摘要】 以某电解铝厂为研究对象,从大气、土壤、植物受氟污染的状况进行分析,研究了气氟污染物在环境中的迁移转化。结果表明:(1)大气、土壤含氟量与距污染源的距离呈负相关。(2)植物体含氟量因距离和种类的不同而有较大差异,主要的受害部位为叶片,出现明显的伤害症状甚至整株坏死。针对此污染状况,应升高烟囱的高度,增加净化处理设施,在厂区周围营造防护林带。更多还原

【Abstract】 In this experiment,the sample of air,soil and plant in the diffent distance from the factory of aluminum electrolysis in Yuncheng Shanxi provincewere gathered.The fluorine contents were determined,it showed that(1) fluorine content in the soil and atmosphere was inversely correlated with its distance from the pollutin source;(2) The conetent of fluorine.nearby plants varied with distances and diffent plants.The magor infected parts was in leaves,having significant symptom or even necrosing through the plants.According to this,the suggested measure for pollution conteol is presented.更多还原
