Epidemiology of lung cancer in foundries.

Occupations involving exposure to hot metal have been associated with elevated lung cancer mortality in many mortality statistics. Metalworkers have also been more common among lung cancer cases in some case control studies. Recent cohort studies in iron and steel foundries have revealed an increased risk of lung cancer among foundry workers. In the foundry air, carcinogenic substances such as polycyclic aromatic hydrocarbons have been identified.
