摘要
提出了一种监测车间空气污染物分布的新方法,采样工具简单不需抽气泵,样品不必用高纯溶剂淋洗,能测定各采样点上实际的累计污染物浓度。
A novel method for determining the distribution of pollutants in workshops was described. The gas pump was not needed when sampling. The complex pretreatment of sample was avoided. Sampling was a static adsorption pro- cess, the analytic results showed the real concentration of pollutants at the sampling point.
