An-otherstudyconductedbyJeanette Sher-man,M.D.,ofworkmen'scompensation cases found auto-industry foundry workers suffer a considerably higher rate of chronic lung disease than all other auto workers. Although smoking adds to the risk of lung disease, studies show that foundry workers who don't smokedevelop lung disease at two and one-half times the expected rate for the generalpopulation. Foundry work consists of several
