长期接触木材加工过程中所产生的大量木粉尘,可直接危害工人的健康,如引起鼻炎、慢性支气管炎、肿瘤、哮喘甚至尘肺等疾患。为了解木粉尘浓度与木尘肺发病关系,为制订木粉尘卫生标准提供依据,我们对海口市五间木材加工厂进行了调查,并用统计学方法进行推算粉尘容许浓度,现将结果报告如下。 Long-term exposure to large quantities of wood dust generated during wood processing can directly endanger the health of workers such as rhinitis, chronic bronchitis, cancer, asthma and even pneumoconiosis. In order to understand the relationship between the wood dust concentration and the incidence of wood pneumoconiosis, to provide the basis for the development of wood dust hygiene standards, we conducted a survey on five wood processing plants in Haikou and calculated the allowable dust concentration by statistical methods. The results are reported as follows.
