摘　　要：目的探讨工作场所空气中粉尘浓度检测过程的重要影响因素。方法选择某陶瓷企业原料车间作为采样现场,选取4个接尘作业岗位用5μm孔径聚氯乙烯滤膜进行总尘和呼尘采样,重量法计算粉尘浓度,并测定粉尘分散度。结果测定粉尘中有96.80%的粒子未能被5μm孔径的聚氯乙烯(PVC)滤膜捕集。结论粉尘浓度测定结果偏低,该工作场所空气中粉尘浓度情况未能真实反映,应选择适用的采样介质。Objective To explore the influencing factors of test method and evaluation method of dust in the workplace air. Methods One workshop in a factory was selected as the sampling location and 4 positions were chosen for total dust and respirable dust sampling,the gravimetric analysis was used to determine the total volume of dust and calculate its concentration,and disparity of the dust were also analyzed. Results It was found that 96. 80% particles whose grain diameter was below 5 μm weren’t collected by the PVC filter membranes of 5 μm aperture. Conclusion This test results show that the dust concentration is on the low side,and the determine results can not reflect the real situation of the dust in the workplace air.
