为了解西宁市大气飘尘中苯并(a)芘(以下简称BaP)的污染程度,我们在1985年进行了测定,摘要报告如下: 选点和分析方法:在市内按功能分区选采样点四个,在远郊区选点一个作为对照点。分别在采暖期和非采暖期连续采样三天。同时记录气温、气压。 用柱层析分离,用南京产的DN600型大气飘尘采样器。荧光分光光度计测其强度,计算含量。回收率为93～105％。
In order to understand the pollution degree of Benzene (a) pyrene (hereinafter referred to as BaP) in the airborne dust in Xining City, we conducted the measurement in 1985 and the summary report is as follows: Point Selection and Analysis Method: A, select a point in the outer suburbs as a control point. Respectively, in heating and non-heating continuous sampling for three days. At the same time record the temperature and pressure. Column chromatography, with Nanjing produced DN600 atmospheric dust sampler. Fluorescence spectrophotometer to measure the intensity, calculate the content. The recovery rate is 93 ~ 105%.
