Abstract
Open lung biopsy specimens from two welders and air samples from their workplace environments were examined with the electron probe microanalyzer. X-ray analysis showed that the majority of particles found in the lung tissue from both workers and in the air samples to be composed of varying amounts of iron, chromium, manganese and nickel, the major components of some types of stainless steel. Based upon these analyses, it was concluded that the majority of the particles in both biopsy specimens were a result of the workplace environment. Both of the cases examined presented welder's siderosis. The large number of aluminum particles identified in 1 of 2 could account for the severe nature of the siderotic condition; however, further experimentation would be required to resolve the question whether the aluminum particles are related to the lung fibrosis.
