第一章 生产性粉尘(续) 六、生产性粉尘的卫生标准 (一)粉尘容许浓度的概念 为了控制生产性粉尘对工人身体健康的损害,有些国家对生产场所空气中粉尘的容许浓度均制订了本国的卫生标准。粉尘容许浓度就是指生产场所空气中可以容许存在的粉尘浓度的极限。由于各国对粉尘容许浓度的概念理解不同,所以在制订和执行粉尘容许浓度上也各不相同。例如我国和苏联采用最高容许浓度, Chapter One Productive Dust (Cont’d) VI. Hygienic Standards for Producing Dust (I) Concept of Admissible Concentration of Dust In order to control the health damage caused by productive dust to workers, some countries have formulated allowable concentrations of dust in the air at the production sites The country’s health standards. Permissible dust concentration means the limit of dust concentration that can be present in the air at the production site. Because countries have different understandings of the concept of permissible dust concentrations, they also differ in the formulation and implementation of permissible concentrations of dust.
