Welding, a fabrication process that joins metals or thermoplastics by causing coalescence, is indispensable in modern society and ubiquitous in industry. Welding generates fumes that contain several metals and gases that comprise fine and ultrafine particles with the potential for adverse effects. Although health risks of welders have been evaluated in different populations, occupational exposure to welding fumes is still considered to be an important health problem, especially in developing countries. The aim of this study was to investigate the effects of welding fume exposure on important oxidative stress parameters such as superoxide dismutase (SOD), catalase (CAT), glutathione reductase (GR), total glutathione (GSH), glutathione peroxidase (GPx), malondialdehyde (MDA), and 8-hydroxy-2′-deoxyguanosine (8-OHdG) in Turkish welders ( n = 48). The influence of confounding factors such as age, smoking habits, alcohol consumption, and duration of exposure on the studied parameters was also analyzed. In our study, significant decreases in the levels of GSH and activities of CAT, SOD, and GPx and significant increases of MDA, 8-OHdG levels and GR activity were found in the workers compared to the controls. There was a negative correlation between GSH levels and alcohol usage. Also, older workers (≥35 years) had significantly higher GR levels than younger workers. But smoking and alcohol usage, duration of exposure, and utilization of protective measures had no significant effect on the studied parameters in the workers. These results indicate that occupational exposure to welding fumes appears to induce oxidative stress and oxidative DNA damage.
ÖZET Metallerin kesilmesi ve birleştirilmesi işlemlerinde kolay ve hızlı bir teknik olan kaynak yöntemi, imalatçılar ve tamirciler tarafından yaygın olarak kullanılmaktadır. Dünyada milyonlarca insan kaynak işleminde sağlıksız ve güvensiz şartlar altında çalışmaktadır. Kaynakçılıkta işin niteliğine bağlı uygulanan kaynak yöntemi, kaynak yapılan malzemenin kimyasal yapısı, yanma gazı, akım şiddeti, ark gerilimi, kaynak hızı ve süresi, ana malzeme üzerindeki kaplama maddeler ve boyalar, kaynakta kullanılan elektrodun yapısı gibi etkenlere bağlı riskler oluşmaktadır. Kaynakçılıktaki temel olası tehlikeler; toz, kaynak gazı ve dumanı gibi iş yeri ortam havasının kirliliği, elektromanyetik radyasyon, elektrik, gürültü, yangın ve patlama olmakla birlikte kaynakçıların kaynak dumanı yoluyla, önemli toksik metaller (Pb, Ni, FeO, Cu, Cd, F, Mn, Cr gibi) ve gazlara (CO, NO, O 3) maruz kaldıkları gösterilmiştir. Kaynak dumanının genel toksik etkileri, kaynak yapılan ortam havasında bulunan toksik gaz ve metallerin cinsine, konsantrasyonuna, maruz kalınan düzeylerine ve sigara içme alışkanlıklarına bağlı olarak değişebilir. Kaynak işçilerinde görülen bronşit, hırıltılı solunum, bozulmuş pulmoner fonksiyon, kronik obstrüktif akciğer hastalığı, metal duman ateşi, akciğer kanseri, nörotoksisite ve böbrek toksisitesi gibi sağlık sorunları ile kaynak işlemi sırasında açığa çıkan kaynak dumanı maruziyeti arasında güçlü bir ilişki olduğu gözlenmiştir. Bu derleme kapsamında, kaynak işçilerinde kaynak dumanına mesleki maruziyete bağlı olası toksik etkiler kapsamlı olarak değerlendirilecek, kaynak dumanından korunma yöntemleri ve yasal düzenlemeler hakkında bilgi verilecektir. Anah tar Ke li me ler: Kaynak yapma; kaynak dumanı; iş sağlığı; toksisite ABS TRACT The welding process, an easy and fast technique for cutting and joining metals, is widely used by manufacturers and repairers. Millions of people around the world work under unhealthy and insecure conditions in the welding process. Depending on the nature of the work in welding, the welding process creates risks related to the factors such as chemical structure of the welding material, combustion gas, current intensity, arc voltage, welding speed and time, coating substances and paints on the main material, the structure of the electrode used in welding. The main potential hazards in welding are the pollution of the workplace air such as dust, welding gas and fumes, electromagnetic radiation, electricity, noise, fire and explosion, as well as welders are shown to be exposed to crucial toxic metals and gases through welding fumes. General toxic effects of welding fumes may vary depending on the type and concentrations of toxic gases and metals, their exposed levels, and smoking habits. It has been observed that there is a strong relationship between the exposure of welding smoke during welding process and the health problems such as bronchitis, wheezing, impaired pulmonary function, chronic obstructive pulmonary disease, metal smoke fever, lung cancer, neurotoxicity, and renal tox...
