OBJECTIVE: To investigate associations between exposure to pot emissions ( @entity1388 , @entity12546 ) and mortality from @entity1030 , @entity7864 volatiles and mortality from diseases related to @entity731 , and @entity1223 and mortality from @entity299 . METHODS: Mortality between 1962 to 1991 was investigated in a cohort of 1085 @entity1 hired by a Norwegian @entity5715 smelter between 1922 and 1975. Associations between cumulative exposure and mortality were investigated through @entity5047 analysis based on national mortality rates; temporal relations were explored by considering exposures only within specific time windows. Circulatory mortality was also investigated by Poisson regression analysis. RESULTS: There were 501 deaths v 471.3 expected in the cohort. The excess was confined to short term workers and did not seem to be associated with exposures in the smelter. Analysis of mortality among the 661 @entity1 with at least three years employment showed associations between cumulative exposure to tar 40 years before observation and @entity731 mortality (P = 0.03), and between exposure to pot emissions 20-39 years before observation and mortality from @entity1030 (P = 0.06). No association was found between exposure to @entity1223 and mortality from @entity299 , but cerebrovascular mortality was associated with exposure to pot emissions (P = 0.02). Results for @entity731 and @entity66 were confirmed through Poisson regression analysis. CONCLUSIONS: The data support previous findings of increased mortality from @entity299 in workers exposed to tar, and some support is also provided for earlier reports of increased respiratory mortality in potroom workers.
