Mortality experience among chromeplating workers. Initial findings.

摘要: A retrospective cohort study was conducted in nine chromeplating plants to examine the mortality of workers employed for at least one year during period January 1951-December 1981. The group totaled 178 individuals, 116 whom were from "hard" and 62 "bright" plants. Vital status ascertainment 97% complete. total number deaths fairly close expected figure (15 observed, 15.2 expected), whereas tumors exceeded (8 4.2 expected). Individuals distinguished into two subcohorts depending on exposure intensity, which much higher hard than bright chromeplating. Most cancer occurred among chromium platers, excess against rate being statistically significant (7 2.7 expected, p = 0.02). All lung this subcohort (3 0.7 0.03). increased platers seems be related intensity strongly suggests need further studies larger cohorts confirm carcinogenicity chromic acid man.
