      <subfield code="a">In this article the particle size distributions and bulk fume densities are used to estimate, using mathematical models, both regional pulmonary deposition and regional pulmonary exposure. The limitations of the deposition model did not account for enhanced deposition due to interception and electrostatic attraction, and there may be inaccuracies in the estimation of diffusion diameters. Assuming that the estimates of regional deposition are reasonably accurate, it is possible that there will be a different exposure-response relationship for each type of fume. This hypothesis should be of interest to anyone intending to study pulmonary disease in welders</subfield>
