Leukemia risk and occupational electric field exposure in Los Angeles County, California.
The authors analyzed data on electric fields from a prior study of occupational magnetic field exposure and leukemia risk conducted in Los Angeles County, California, in 1972-1990. Ranking of exposure differed somewhat for magnetic and electric fields. The odds ratios were 1.22 (95% confidence interval (CI) 0.80-1.86) and 1.15 (95% confidence interval 0.78-1.72) for medium and high exposure categories, respectively, and there was no clear evidence of an exposure-response relation (odds ratio for 10 V/m increase = 1.05, 95% CI 0.95-1.16). Although not conclusive, our analyses provide little support for an association between occupational electric field exposure and leukemia.
