【摘要】：目的探讨锰焊烟尘和锡焊烟尘对电焊作业工人肺通气功能的影响。方法采用判断抽样方法,以广州市某电子厂从事锡焊作业的485名工人为锡焊烟尘组;以广州市某汽车零部件厂从事锰焊作业的110名工人为锰焊烟尘组,以该厂无职业病危害因素接触的134名人员为对照组。对3组人群进行肺功能检查,分析不同电焊工种对其影响。结果锡焊烟尘组工作场所空气中的铅烟、二氧化锡和锰焊烟尘组工作场所空气中的锰及其无机化合物、电焊烟尘的时间加权平均浓度均不超过国家职业卫生接触限值。锰焊烟尘组人群的用力肺活量、第1秒用力肺活量、最大呼气流量的实测值占预计值百分比以及最大呼气中段流量、25%肺活量最大呼气流量、50%肺活量最大呼气流量均分别高于对照组和锡焊烟尘组(P0.05),但对照组和锡焊烟尘组人群上述各指标分别比较,差异均无统计学意义(P0.05)。锰焊烟尘组人群肺通气功能障碍检出率分别高于其余2组(44.5%vs 11.9%,44.5%vs 19.4%,P0.01);但对照组和锡焊烟尘组人群该指标比较,差异无统计学意义(P=0.046)。结论锰焊烟尘接触可导致作业工人发生肺通气功能障碍;暂未发现锡焊烟尘对作业工人肺通气功能造成影响。
[Abstract]:Objective to investigate the effect of manganese welding dust and tin welding dust on pulmonary ventilation function of workers exposed to electric welding. Methods 485 workers who were engaged in tin welding in an electronic factory in Guangzhou were selected as tin welding dust group by the method of judging sampling. 110 workers engaged in manganese welding in a Guangzhou auto parts factory were taken as the manganese welding dust group, and 134 workers who were not exposed to occupational hazards were used as the control group. Three groups of people were examined for lung function, and the effects of different types of welding workers were analyzed. Results the time weighted average concentration of lead fume in the workplace air, manganese and its inorganic compounds in the workplace air of the tin welding dust group and the tin dioxide and manganese welding dust group did not exceed the national occupational health exposure limit. The forced vital capacity, forced vital capacity in the first second, the measured percentage of the maximum expiratory flow in the predicted value and the maximal mid expiratory flow, and the maximal expiratory flow in the 25% vital capacity group in the manganese welding dust group. The maximal expiratory flow of 50% vital capacity was higher than that of the control group and tin welding dust group (P0.05), but there was no significant difference between the control group and the tin welding dust group (P0.05). The detection rate of pulmonary ventilation dysfunction in manganese welding dust group was higher than that in the other two groups (44.5%vs 11.9%, 44.5% vs 19.4%, P0.01). However, there was no significant difference between the control group and the tin welding dust group (P < 0. 046). Conclusion exposure to manganese welding dust can lead to pulmonary ventilation dysfunction in workers, but no effect of tin welding dust on pulmonary ventilation function has been found.
