Mortality experience was investigated at a plant in Ontario that produced viscose rayon, with carbon disulfide as a main raw material.
Work-history records for 279 deceased workers at the plant (plant A) were obtained and compared with those for 511 deceased workers at a pulp and paper plant in the same city (plant B).
In a proportional mortality analysis, using as a reference the general population of Ontario, at both plants there were fewer deaths from ischemic heart disease than expected (the proportional mortality ratios [PMRs] were 83 at plant A and 95 at plant B) but more deaths than expected from cerebrovascular disease (PMRs were 115 at plant A and 149 at plant B).
In a subgroup of plant A workers who had been employed in high-carbon-disulfide exposure areas, deaths from ischemic heart disease were less than expected (PMR=82), particularly among those who worked in these areas for more than 5 y. Most deaths occurred among those aged 65 y or more.
Mortality from strokes, however, was greater than expected (PMR=207, p<. 05) ; the excess was confined to workers who died at age 65 y or older (PMR=229, p=01).
Proportional mortality from strokes was also increased in the pulp workers among those who died at age 65 y or older (PMR=153).
In a case-control analysis, the risk of ischemic heart disease at plant A was slightly less than at plant B (odds ratio [OR]=0.92,95% confidence interval [CI]=0.60-1. (...)
