摘要
前言凡使用含氟矿石(如冰晶石、磷矿石等)作原料的工厂,在碾磨、加热、酸化等过程中,以及利用含氟化合物作为接触剂、助熔剂的各种工艺过程的生产中,都会散发出大量的含氟废气与粉尘污染环境。
1.Afforestation experiment has been taken out in a phosphorus fertilizer factory for 118 in-dividuals of 65 species.After 18months of afforesting,only 75 individuals of 51 species arealive.2.The response of trees to fluoride pollution varies with tree species,concentrationof air pollutant and distance from pollution source.3.Total F content in leaves shows thatall trees have the ability of absorpting and accumulating fluoride and the purgative effect toair pollution.4.According to their response to F pollution,the survival trees are dividedinto three groups:strong resistant,meso-resistant and weak resistant.
