Abstract |
This study evaluated particulate matter in combined induced sputum (IS) and oxidation in exhaled breath condensate (EBC), in order to test whether underlying inflammatory changes are present in asymptomatic welders. Thirty welders from the Israel Defence Forces exposed to aluminium/iron (Group 1), 16 exposed to cadmium/chromium/iron/lead/nickel (Group 2) and 27 non-exposed administrative staff were studied. IS was recovered and particle size distribution, hydrogen peroxide and pH were measured; exhaled breath condensate also was collected. Group 2 had a higher percentage of neutrophils than all other participants and a higher percentage of particles of more than 2µm in diameter. Percent particles and years of exposure highly correlated. All welders' EBC samples had higher concentrations of hydrogen peroxide than controls. Other findings are discussed. |
