【摘要】：目的分析建筑陶瓷粉尘对作业工人的职业健康危害。方法选择某建筑陶瓷厂885名粉尘作业工人为接尘组,以195名非粉尘作业工人为对照组,对2组人员进行职业健康检查,结合工作场所空气中粉尘测定结果进行分析。结果该陶瓷厂工作场所陶瓷粉尘中游离二氧化硅(Si O2)质量分数为21.1%~38.0%(28.3±6.5)%。总粉尘时间加权平均浓度(CTWA)为0.10~8.20 mg/m3,超标率28.95%(11/38),最高超过职业接触限值7.2倍;呼吸性粉尘CTWA为0.10~1.79 mg/m3,超标率为18.42%(7/38),最高超过职业接触限值1.6倍。接尘组诊断陶工尘肺6例(壹期5例,贰期1例),检出率为0.68%。粉尘作业禁忌证检出率为1.69%(15/885)。接尘组肺通气功能异常检出率高于对照组(9.60%vs 2.56%,P0.01)。接尘组工人心电图异常率高于对照组(8.81%vs 1.54%,P0.01)。结论建筑陶瓷粉尘对作业工人健康危害较为严重。有关企业应加强对粉尘危害的控制工作,保护工人健康。
[Abstract]:Objective to analyze the occupational health hazards of workers exposed to building ceramics dust. Methods 885 workers exposed to dust in a building ceramics factory were selected as dust exposure group and 195 non-dust exposed workers as control group. Results the mass fraction of free silica / Sio _ 2 in the workplace ceramic dust was 21.1mm ~ 38.0 卤6.5g / m ~ (3). The mean concentration of CTWAs was 0.100.20 mg / m ~ (3), and the highest rate was 28.9511 / 38 ~ (th), the highest was the total dust time weighted average concentration (CTWAs) of 28.3 卤6.5g / m ~ (3) in the ceramic dust of the ceramic factory, and the total dust time weighted average concentration (CTWA) was 0.10 ~ 8.20 mg / m ~ (3). 7.2 times the occupational exposure limit; The CTWA of respiratory dust was 0.10 ~ 1.79 mg / m ~ (3), the rate of exceeding the standard was 18.42 / 7 / 38, the highest value was 1.6 times higher than the occupational exposure limit, 6 cases (5 cases) of pneumoconiosis of ceramic workers were diagnosed in the dust exposure group. The detectable rate of contraindications in dust-exposed group was 1.69 / 885%. The abnormal rate of pulmonary ventilation function in dust-exposed group was higher than that in control group (9.60 vs 2.56 P 0.01). The abnormal rate of electrocardiogram in the dust exposed group was higher than that in the control group (8.81% vs 1.54% P0.01.Conclusion the abnormal rate of electrocardiogram in the dust exposure group is higher than that in the control group (8.81% vs 1.54% P0.01). The health hazards of industrial workers are relatively serious. The enterprises concerned should strengthen the control of dust hazards, Protect the health of the workers.
