摘要
对我国有代表性的4家硬质合金生产厂及2家工具研磨厂的1237名单纯接触硬质合金粉尘工人及502名对照工人进行分析,结果表明,接触组呼吸系统症状、肺功能异常检出率、血清铜蓝蛋白及尿钴含量均明显高于对照组。X线胸片检查发现8例尘肺,患病率为0.65%,发病平均接尘工龄为25.2年。上述结果说明,硬质合金粉尘具有致肺纤维化作用,并可引起尘肺。
cross-sectional study, with 1 237 employees solely exposed to hald alloy dust and 502 controls in four hard rnetal works and two tool and grinder manufacturers in China,was conducted.Results showed prevalence of symptoms of respiratory system,and abnormalities in lung function and serum lev-el of ceruloplasmin and urine cobalt content in exposed group were significantly higher than those in con-trols.Eight cases of pneumoconiosis were detected by chest X-ray filmLs with a prevalence of 0.65%and an average length of employment in dust environrnent of 25. 2 years. It suggested hard alloy dust could cause pulmonary firbrosis and pneumoconiosis in exposed workers.
