Identification of the mechanism for the association between pneumococcal pneumonia and exposure to welding fumes

Professor Jonathan Grigg

Studies suggest that workers exposed to welding fumes have increased vulnerability to pneumococcal pneumonia and pneumococcal septicaemia.  This link is not observed after the end of a welder’s working life, suggesting that the stimulus is reversible and occupational.  Professor Jonathan Grigg at Queen Mary University of London (QMUL) is leading this study, which will contribute significantly to the development of a policy to reduce the occupational exposure for welders.  The Colt Foundation funding started in 2013 and is due to complete at the end of 2014.  One of the young researchers working with Professor Grigg on the project presented details of the progress to date at Colt Research Day in January 2014.
