粉尘浓度是评价防尘措施效果,反映粉尘危害程度,进行粉尘浓度与尘肺发病关系调查研究的客观指标。定点瞬时滤膜测尘法,已是多年来常用的测尘方法,然而能否衡量工人实际接触尘量,尚有争论。为此我们对某厂茶叶粉尘作业工人采用个体携带式粉尘采样与定点瞬时滤膜测尘两种方法测定三种粉尘浓度,所得 Dust concentration is to evaluate the effect of dust control measures, reflecting the degree of dust damage, the dust concentration and the incidence of pneumoconiosis research objective indicators. The fixed-point instantaneous filter dust detection method has been the commonly used method of dust measurement over the years. However, there is still controversy about whether workers can actually measure dust exposure. To this end, we use a personal tea dust factory workers carrying dust sampling and fixed-point instantaneous membrane dust two methods to determine the concentration of three kinds of dust, the income
