A mortality study was carried out among workers employed in the
Arcelor and GTS Industries plants in Dunkerque. It was aimed at
assessing the possible association between iron oxide exposures
and lung cancer risk. The cohort comprised 16,742 males and 959
females. Among males, the observed mortality was lower than
expected for all causes. No significant lung cancer excess was observed
for exposure to iron oxides and no dose-response relationship
with intensity and duration of exposure.
