The oxidized states of chromium III and chromium VI are the most important forms of the chemical. Cr (VI) fume is highly toxic and can damage the eyes, skin, nose, throat, and lungs and is a known carcinogenic. [Assessment of occupational exposure of welders based on determination of fumes and their components produced during stainless steel welding]. Epidemiological studies support a link between welding and lung cancer, particularly stainless steel fume which contains carcinogenic metals like hexavalent chromium and nickel. The composition of the base metals, the welding materials used, and the welding processes affect the specific compounds and concentrations found in the welding fume. Welders are exposed to these elements if they inhale welding fume. Sci Total Environ. 53 0 obj <>stream Inhaled ma… Acute poisoning is an emergency. Fumes from mild steel welding contain mostly iron with small amounts of additive metals (chromium, nickel, manganese, molybdenum, vanadium, titanium, cobalt, copper etc. Our results showed that welding fumes, Cr (VI), and nickel might contribute independently to the excess lung cancer risk associated with welding. A delayed anaphylactoid reaction was reported in a male worker occupationally exposed to chromium vapors from chromium (VI) trioxide baths and chromium fumes from steel welding. We developed a welding-process exposure matrix from measurements of these agents, and this was linked with welding histories from a job-specific questionnaire to calculate cumulative exposure variables.  |  This site needs JavaScript to work properly. The fumes from metal inert gas stainless steel (MIG/SS) welding also had a toxic effect but this was 2-3 times greater than that expected from their soluble Cr(VI) content based on the activity of soluble Cr(VI) from pure chromium compounds. Industrial processes widely utilize stainless steel due to its corrosion resistance and durability. Logistic regression models were fitted to estimate odds ratios with confidence intervals conditional on study, and they adjusted for age, smoking, and working in other at-risk occupations. 0 Study objectives: To determine the prevalence of chromium toxicity among workers in welding industry, and to correlate the occupational exposure for chromium with respiratory morbidity symptoms. Trivalent Chromium is a trace element present in our body which regulates which, in small amounts, facilitates in certain bodily functions such as digestion of food and maintaining glucose levels. Chromium (Cr) is a type of heavy metal that is used in many industrial applications; A primary risk factor for Chromium Toxicity is the exposure environment; industrial welders are at a high risk due to the nature of their work environment.
