[Current status and research progress of occupational health monitoring in welding fume operations].

Welding operations are widely present in the manufacturing production process, involving a large number of occupational groups, and are the key occupations where work injuries and occupational diseases occur in China. For different welding processes and welding materials, the content and focus of occupational health monitoring are different. At present, the item of occupational health examination in welding operation is in poor consistency with the on-site exposure of occupational hazard factors, and it is mainly concentrated in the stage of disease development, which can not reflect the early health damage caused by welding dust exposure in time. The emergence of biomarkers of welding dust can make up for this defect. Therefore, it is of great significance to describe the current situation of occupational health monitoring of welding dust and summarize the research progress of related biomarkers for the early prevention of diseases caused by welding dust and the practice of occupational health monitoring.焊接作业广泛存在于制造业生产过程中，涉及职业人群数量众多，是我国工伤和职业病发生的重点行业。针对不同焊接工艺、焊接材料，职业健康监护的内容和侧重点不同。当前焊接作业的职业健康检查项目与职业病危害因素现场暴露一致性较差且主要集中在疾病发展阶段，不能及时反映电焊烟尘暴露所导致的机体早期健康损害，而电焊烟尘生物标志物的出现能够弥补这一缺陷。因此，描述电焊烟尘职业健康监护现状，并综述相关生物标志物研究进展，对电焊烟尘所致疾病的早期预防和职业健康监护实践具有重要意义。.
