呼市南郊大气氟化物的测定

本文采用静态石灰滤纸法测定大气中微量氟化物浓度,並论述了测定方法及其方法的优越性。总结了1982～1984连续三年对农牧学院大气氟化物浓度的测定结果。参照国外文献对测定结果进行了初步分析。提出农牧学院大气受到了氟污染,其污染程度呈逐年增加趋势,即1982<1983<1984,同一年中污染程度是冬季大于夏季。同时利用包头环保科研所提出的石灰滤纸法与滤膜法的换算关系,将本文测定结果进行了换算,並与正常情况下大气氟化物浓度做了比较。

The determination of the amount of flaoride in air in the southern suburbs of Huhehot

The concentration of Fluoride amount in air was surveyed and de- termined with L T P method, and the advantage of L T Pwas discussed in this essay, After summing up testing results of Fluoride amount tak en in the air over our institute campus from 1982 to 1984, and refering to some data concerned, I would point out that the air over our campus had polluted with Fluoride and the pollution degree increased year after year during the three years and it was greater in winter than in summer in the same year, I converted the data got with L T P into that with an ordernary method. A comparision was made betweennormal and excessive Fluoride amount in air.
