Abstract

Purpose: Welders are more likely to develop neurobehavioral disorders because of their exposure to neurotoxic metals such as manganese. This study aimed to measure the neurobehavioral performance of welders occupationally exposed to manganese at welding enterprises and its relationship with the workplace environment.

Methods: It is a comparative cross-sectional study carried out on 130 welders working at 50 welding enterprises in Menoufia governorate, Egypt, compared to 130 non-occupationally exposed controls.

Results: It was found that the environments of the studied welding enterprises had levels of respirable dust, manganese, and total welding fumes that exceeded internationally permissible limits. In addition, the mean blood manganese levels were significantly higher among welders (4.16 ± 0.61) than the controls (1.72 ± 0.41). Welders had a significantly higher prevalence of neurological manifestations and lower performance of neurobehavioral tests. Lower neurobehavioral performance among welders was significantly correlated with increased work duration and blood levels in some tests.

Conclusion: To lessen the fumes in the breathing zone of workers, it is therefore strongly recommended to regularly wear high-quality personal protective equipment, especially masks, and to ensure proper ventilation.

埃及电焊工接触含锰焊接烟尘对神经系统和神经行为的影响。

目的：由于接触锰等神经毒性金属，电焊工更容易出现神经行为障碍。本研究旨在测量焊接企业中接触锰的焊工的神经行为表现及其与工作场所环境的关系：这是一项横断面比较研究，研究对象是在埃及梅努菲亚省 50 家焊接企业工作的 130 名电焊工与 130 名非职业性接触锰的对照者：结果：研究发现，所研究的焊接企业环境中的可吸入粉尘、锰和焊接烟尘总量均超过了国际允许限值。此外，电焊工的平均血锰水平（4.16 ± 0.61）明显高于对照组（1.72 ± 0.41）。电焊工的神经系统症状发生率明显较高，神经行为测试成绩较低。电焊工的神经行为表现较差与工作时间的延长和某些测试的血液水平有明显的相关性：因此，为了减少工人呼吸区的烟雾，强烈建议定期佩戴高质量的个人防护设备，尤其是口罩，并确保适当的通风。

期刊介绍： International Archives of Occupational and Environmental Health publishes Editorials, Review Articles, Original Articles, and Letters to the Editor. It welcomes any manuscripts dealing with occupational or ambient environmental problems, with a special interest in research at the interface of occupational health and clinical medicine. The scope ranges from Biological Monitoring to Dermatology, from Fibers and Dust to Human Toxicology, from Nanomaterials and Ultra-fine Dust to Night- and Shift Work, from Psycho-mental Distress and Burnout to Vibrations. A complete list of topics can be found on the right-hand side under For authors and editors. In addition, all papers should be based on present-day standards and relate to: -Clinical and epidemiological studies on morbidity and mortality -Clinical epidemiological studies on the parameters relevant to the estimation of health risks -Human experimental studies on environmental health effects. Animal experiments are only acceptable if relevant to pathogenic aspects. -Methods for studying the topics mentioned above.
