摘　　要：本文用现场平行采样的方法研究石棉造纸行业的各扬尘点粉尘重量浓度与纤维计数浓度间的转换关系。结果认为,可以对各不同工作点分别找出两种浓度的转换关系,可据此将该厂过去测定的重量浓度记录转换为纤维计数浓度,为进行石棉纤维计数浓度的剂量-反应关系计算提供基本资料。Relationship between gravimetric and fibre concentrations of airborne asbestos dust has been established by simultaneously sampling with two methods on 15 sites in an asbestos paper mill. Regression analysis shows that there are significant relationships between the two types of concentration, but diffent conversion factors should be used in different sampling sites. Based on these conversion factors, the past mass concentration records can be transferred into fibre concentration, and hence the fibre dose-response relationship is possible to be established.
