【摘要】：目的探討錳焊煙塵和錫焊煙塵對電焊作業(yè)工人肺通氣功能的影響。方法采用判斷抽樣方法,以廣州市某電子廠從事錫焊作業(yè)的485名工人為錫焊煙塵組;以廣州市某汽車零部件廠從事錳焊作業(yè)的110名工人為錳焊煙塵組,以該廠無職業(yè)病危害因素接觸的134名人員為對照組。對3組人群進行肺功能檢查,分析不同電焊工種對其影響。結果錫焊煙塵組工作場所空氣中的鉛煙、二氧化錫和錳焊煙塵組工作場所空氣中的錳及其無機化合物、電焊煙塵的時間加權平均濃度均不超過國家職業(yè)衛(wèi)生接觸限值。錳焊煙塵組人群的用力肺活量、第1秒用力肺活量、最大呼氣流量的實測值占預計值百分比以及最大呼氣中段流量、25%肺活量最大呼氣流量、50%肺活量最大呼氣流量均分別高于對照組和錫焊煙塵組(P0.05),但對照組和錫焊煙塵組人群上述各指標分別比較,差異均無統(tǒng)計學意義(P0.05)。錳焊煙塵組人群肺通氣功能障礙檢出率分別高于其余2組(44.5%vs 11.9%,44.5%vs 19.4%,P0.01);但對照組和錫焊煙塵組人群該指標比較,差異無統(tǒng)計學意義(P=0.046)。結論錳焊煙塵接觸可導致作業(yè)工人發(fā)生肺通氣功能障礙;暫未發(fā)現(xiàn)錫焊煙塵對作業(yè)工人肺通氣功能造成影響。
[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.
