||Urinary 8-isoprostane and 8-OHdG concentrations in boilermakers with welding exposure
||Feb. 2008, Vol.50, No.2, p.182-189. Illus. 35 ref.
||To investigate the association of exposure to fine particulate matter (PM 2.5) with DNA damage and oxidative stress in boilermakers exposed to welding fumes, 41 workers were monitored over 24 hours during which baseline, post-shift, bedtime, and next morning urine samples were collected. Blood samples were also collected pre-shift and the following morning. Twenty-two unexposed workers participated as controls. Linear regression was used to model changes in u-8-isoprostane and u-8-OHdG. Acute welding fume exposure was found to be associated with a post-shift blunting of systemic inflammation, as measured by 8-isoprostane, in chronically exposed workers. The level of oxidative DNA damage as measured by 8-OHdG was less clear.
