Hexavalent chromium responsible for lung lesions induced by intratracheal instillation of chromium fumes in rats.
Lung toxicity of chromium fumes (Cr fumes) was examined by a single intratracheal instillation into rats of 10.6 mg and 21.3 mg Cr fumes/kg body weight and by repeated (3 times) instillations of 10.8 mg and 21.7 mg Cr fumes/kg. The pathological changes were compared with those induced by single administrations of 3.2 mg and 19.2 mg Na2CO3 solution-insoluble fraction of Cr fumes (Cr-Fr)/kg and 2...
متن کاملBronchial reactions to exposure to welding fumes.
OBJECTIVES To study the airway response and its mechanism to welding fumes in six welders with respiratory symptoms. METHODS Methacholine and welding challenge tests were carried out. The concentration of welding fumes during the exposure test was measured. On two subjects who developed bronchoconstricition to welding challenge, additional tests were carried out including prick, patch, and in...
متن کاملCancer Risk Assessment in Welder’s Under Different Exposure Scenarios
BACKGROUND Welders exposure to nickel and hexavalent chromium in welding fumes is associated with increase of cancer risk in welders. In this study we calculated cancer risk due to exposure to these compounds in welders. METHODS The role of exposure parameters in welders on derived incremental lifetime cancer risk were determined by stochastic modeling of cancer risk. Input parameters were de...

flight. The trip lasted 2.5 h and the kidney was transplanted into ‘D’ after 4 h of cold ischemia at the HVN. During this time, the kidney of ‘C’ remained in cold ischemia until the plane that landed in Granada came back to Barcelona and was transplanted in ‘E’ with 5 h and 15 min of cold ischemia. At 7:30 PM, the transplant was completed and the chain was closed (Fig. 1). The donors of both ho...
متن کاملThe three dimensional distribution of chromium and nickel alloy welding fumes.
In the present study, the fumes generated from manual metal arc (MMA) and submerged metal arc (SMA) welding of low temperature service steel, and the chromium and nickel percentages in these fumes, were measured at various horizontal distances and vertical heights from the arc in order to obtain a three dimensional distribution. The MMA welding fume concentrations were significantly higher than...
