两种不同采样方法对空气中铅检测结果的影响
Comparison of Air Lead Levels by Two Sampling Approaches
摘要
Abstract
Abstract: [ Objective ] To compare the time weighted average concentrations (TWAC) of lead in air by individual sampling and fixed point sampling. [ Methods ] Air lead was parallel sampled by individual sampling and fixed point sampling at workplace. According to the Methods for Determination of Lead and Its Compounds in the Air of Workplace (GBZ/T 160.10-2004), the time weighted average concentrations of lead in air were measured and compared. [ Results ] There was no statistically significant difference between the lead TWACs estimated by individual sampling and fixed point sampling at the spots with general ventilation of the selected workplace. But at the spots with local ventilation, the results estimated by the two sampling methods showed statistically significant differences. [ Conclusion ] In workplaces with local ventilation, the results of lead levels in air vary with sampling methods. Individual sampling could better reflect the actual exposure level.关键词
