An environmental and medical evaluation of sulfur-dioxide (7446095), vanadium (7440622) containing dust, and respirable dust containing silica (7631869) at an electric power plant indicates that the gas and the dust are non-toxic at the concentrations found in the plant. Toxic effects of sulfur-dioxide include burning sensations, dryness and pain in the nose and throat accompanied by a dry or productive cough. Symptoms of vanadium poisoning are lung irritation leading to chest tightness, congestion, cough, wheezing, broncho-pneumonia and pulmonary edema. Silica can lead to silicosis. Recommendations include respiratory protection, and pre-employment and periodic screening of employees.
