在职业危害因素现场检测中,目前主要存在两种采样方法:定点采样和个体采样。定点采样和个体采样两者各有优劣,其中定点采样方法简单、节省时间、成本较低,有助于了解作业场所污染的背景值;但在样本量较少时,导致监测结果不能正确反映实际接触水平,从而对结果的准确性产生严重影响~(〔1〕)。个体采样是运用个体采样技术,对工人进行全工作日的连续采样,具有操作复杂、耗费时间、成本较高等特点;但却能更好地反映工人实际接触水
In the field of occupational hazards testing, there are two main sampling methods: fixed-point sampling and individual sampling. Both fixed-point sampling and individual sampling have their own advantages and disadvantages. The fixed-point sampling method is simple, saving time and low cost, which helps to understand the background value of workplace pollution. However, when the sample size is small, the monitoring results can not be correctly reflected The actual level of exposure, which has a serious impact on the accuracy of the results ~ (〔1〕). Individual sampling is the use of individual sampling techniques, continuous sampling of workers on a full working day, with complex operation, time-consuming, high cost and other characteristics; but it can better reflect the actual exposure of workers to water
