玻璃厂氟污染对周围生态环境的影响

不同树种对氟化物的吸收能力有差异.吸收能力和抵抗能力之间并无明显的相关注,因此在氟污染源附近进行环境绿化时,必须选择吸氟和抗氟能力都较强的园林树种.氟污染具有方向性, 可以通过测定不同部位的叶片含氟量来确定污染源的方位.水洗后的叶片含氟量明显下降,说明玻璃厂排放的含氟烟气中,含氟粉尘占有重要地位.对防治玻璃厂的氟污染危害提出了合理的建议.

EFFECT OF FLUORINE POLLUTION RELEASED BY GLASS PLANT ON SURROUNDING ECO-ENVIRONMENT

The absorbability and resistance of various trees are different to fluorine.There is no evident relativity between them. So garden plants which have great abilities to absorb and resist to fluoride must be selected as afforesting the factory.The fluorine concentration is higher in leaves facing the pollution source than backing of it.The fluorine pollution is directive. Therefore,the position of the pollution source can be determined by the analysis of the fluorine concentration in leaves at different position,The fluorine concentration in leaves are evident reduced after washing. It shows that in flue gases from the glass factory,dust fluorides have important position. Finally, some suggestions were proposed for the glass factory to prevent the fluorine pollution.
