Welding is one of the processes which cause multivarious problems to health. It requires considerable attention because of its severe hazards. During welding very harmful fumes and heat are emitted which have adverse effects on the health of the welder and people working in his vicinity. In the present work microfibre glass filter paper (GF/A) was found to be the preferable media for sampling of the fumes from mild steel electric welding electrodes for the evaluation of the trace elemental composition of the fumes. Using neutron activation analysis considerable amounts of the most harmful elements such as Ba, Co, Cr, Sb, Rb, Sc, As and Fe were observed.
焊接是对健康造成多种问题的工艺之一。由于其严重危害，它需要引起相当大的关注。在焊接过程中会释放出非常有害的烟雾和热量，这对焊工及其附近工作的人员的健康有不利影响。在目前的工作中，发现微纤维玻璃滤纸（GF/A）是用于采集低碳钢电焊条烟雾以评估烟雾中微量元素组成的优选介质。使用中子活化分析观察到了大量最有害的元素，如钡、钴、铬、锑、铷、钪、砷和铁。
