In the years of 1980–1990, there were 139 birth records filed in Washington State on which father's occupation was designated as “carbon setter,” a job title specific to aluminum reduction plants of the prebake type. Fifty‐three (53) of these records specified sex of the birth as male, while 86 records specified sex of the infant as female. This gives a sex ratio of 0.381, which is a significant departure from the usual sex ratio at birth (proportion male + 0.512). Surveillance of sex ratio by paternal occupation is a simple method of monitoring for genotoxicity. © 1993 Wiley‐Liss, Inc.
