焊接是用于连接金属的主要工业工艺。职业性接触焊接烟尘是世界范围内一个严重的职业健康问题。油烟对焊工健康的危害程度取决于成分、浓度和暴露时间。这项研究的目的是调查沙特阿拉伯吉达一些行业工人的焊接烟雾暴露水平。在每一家工厂，焊工呼吸区内0.5米范围内的空气在8小时轮班期间进行采样。测定了焊接烟尘的总颗粒物、锰、铜和钼的浓度。焊工呼吸区在焊接过程中测得的8小时平均颗粒物浓度平均值分别为6.3毫克/立方米(工厂1)、5.3毫克/立方米(工厂2)、11.3毫克/立方米(工厂3)、6.8毫克/立方米(工厂4)、4.7毫克/立方米(工厂5)和3.0毫克/立方米(工厂6)。焊接过程中空气中锰、铜和钼的平均值分别为0.010 mg/m~3~0.477 mg/m~3、0.001 mg/m~3~0.080 mg/m~3和0.001 mg/m~3~0.058 mg/m~3。计算的当量暴露值的平均值为：1.50(工厂1)、1.56(工厂2)、5.14(工厂3)、2.21(工厂4)、2.89(工厂5)和1.20(工厂6)。工厂1、2、3和4的焊工暴露在高于SASO限值的焊接烟尘浓度中，这可能会增加呼吸健康问题的风险。
Welding is a major industrial process used for joining metals. Occupational exposure to welding fumes is a serious occupational health problem all over the world. The degree of risk to welder’s health from fumes depends on composition, concentration, and the length of exposure. The aim of this study was to investigate workers’ welding fume exposure levels in some industries in Jeddah, Saudi Arabia. In each factory, the air in the breathing zone within 0.5 m from welders was sampled during 8-hour shifts. Total particulates, manganese, copper, and molybdenum concentrations of welding fumes were determined. Mean values of eight-hour average particulate concentrations measured during welding at the welders breathing zone were 6.3 mg/m3 (Factory 1), 5.3 mg/m3 (Factory 2), 11.3 mg/m3 (Factory 3), 6.8 mg/m3 (Factory 4), 4.7 mg/m3 (Factory 5), and 3.0 mg/m3 (Factory 6). Mean values of airborne manganese, copper, and molybdenum levels measured during welding were in the range of 0.010 mg/m3–0.477 mg/m3, 0.001 mg/m3–0.080 mg/m3 and 0.001 mg/m3–0.058 mg/m3 respectively. Mean values of calculated equivalent exposure values were: 1.50 (Factory 1), 1.56 (Factory 2), 5.14 (Factory 3), 2.21 (Factory 4), 2.89 (Factory 5), and 1.20 (Factory 6). The welders in factories 1, 2, 3, and 4 were exposed to welding fume concentration above the SASO limit value, which may increase the risk of respiratory health problems.
