||A cohort study of mortality among Ontario pipe trades workers
||Sep. 2004, Vol.61, No.9, p.736-742. 8 ref.
||A cohort of 25,285 plumbing and pipe fitting workers in the United States and Canada who entered the trade after 1949 was assembled from union records. Standardized mortality ratios (SMRs) were computed using Ontario (Canada) general population mortality rates as the reference. There were significant increases in lung cancer mortality rates (SMR 1.27). Increased lung cancer risk was observed among workers joining the union as late as the 1970s. A meta-analysis of this study and two earlier studies found significant increases in oesophageal (relative risk - RR 1.24), lung (RR 1.31), and haematological and lymphatic malignancies (RR 1.21). The mortality pattern is consistent with the effects of occupational exposure to asbestos. However, increased risk due to other respiratory carcinogens such as welding fumes cannot be excluded.
