Elevated markers of airway injury
Persons exposed to oil were at increased risk for lower respiratory tract symptoms (risk difference, 8.0). However, lung function did not significantly differ between the groups. Exposed participants also had higher levels of exhaled vascular endothelial growth factor (risk difference, 44.8) and basic fibroblast growth factor (risk difference, 16.0).

A higher proportion of exposed participants had structural chromosomal alterations (risk difference, 27.4), predominantly unbalanced alterations.
Participation in clean-up of a major oil spill was associated with persistent respiratory symptoms, elevated markers of airway injury in breath condensate, and chromosomal damage.
