SUMMARY: Many toxic substances including heavy metals, ozone, carbon monoxide, carbon dioxide, and nitrogen oxides are generated during welding. Ozone (O(3)) is a strong oxidant that generates reactive oxygen species (ROS) in tissue, and ambient ROS exposure associated with particles has been determined to cause DNA damage. Although particles were not generated after welding, ROS and O(3) still persisted for more than 10 minutes. Meanwhile, because …
