摘要
目的了解安康市粉尘危害情况,进一步治理粉尘污染。方法对全市接触矽尘、煤尘等无机粉尘1年以上的3859名作业工人,按照尘肺病检查内容、程序和GBZ 70-2002尘肺诊断标准进行尘肺病检查、诊断,并对生产环境进行劳动卫生学调查及粉尘浓度、分散度、二氧化硅(SiO2)含量测定。结果粉尘浓度平均86.63 mg/m3,游离SiO2含量32.17%;尘肺患病率为11.04%;发病工龄最长35年;最短11个月,平均19.58年。结论尘肺患病率、发病工龄、尘肺病进展均与粉尘浓度及游离S iO2含量高有关。
Objective To explore the status of dust hazard at the enterprises of Ankang city ,provide evidences for controlling dust pollution further. Methods According to GBZ 70 -2002 Diagnostic Criteria of Pneumoeonioses , 3 859 workers exposed in inorganic dust including silica dust and coal dust over one year were examined and diagnosed. Hygiene investigation of the workplaces was carried out , at the same time, dust concentration , dust dispersion degree and the content of silicon dioxide were determined. Results Average concentration of dust was 86. 63 mg/m^3 ; the content of free silicon dioxide was 32. 17% ; prevalence rate of pneumoconiosis was 11.04% ; the longest incidence length of service was 35 years ; the Shortest was 11 months and the average was 19. 58 years. Conclusion Prevalence rate of pneumoconiosis, the incidence length of service and pneumoconiosis progress concern with high dust concentration and free silicon dioxide content. It is suggested that municipal government should strengthen supervision and put pneumoconiosis into legal management.
