矽肺是由于长期吸入大量含有游离二氧化硅的粉尘所引起,以肺部广泛结节性纤维化为主的疾病[1]。在深圳市龙岗区存在一些规模小、人数少、防护差的小型大理石等石材加工企业,为了解此类企业的尘肺发病情况,对石材加工企业劳动者健康状况进行了调查。 Silicosis is caused by prolonged inhalation of large amounts of dust containing free silica, a disease predominantly characterized by extensive pulmonary nodular fibrosis [1]. In Longgang District, there are some stone processing enterprises with small scale, small number and poor protection. To understand the incidence of pneumoconiosis in such enterprises, the health status of workers in stone processing enterprises was investigated.
