Title Leukemia in electric utility workers: The evaluation of alternative indices of exposure to 60Hz electric and magnetic fields
Bibliographic information June 2000, Vol.37, No.6, p.607-617. 36 ref.
Abstract The association between adult leukaemia and exposure to electric and magnetic fields was explored by a case-control study of 31,453 Ontario (Canada) electric utility workers. The percentage of time spent above electric field thresholds of 20 and 39V/m was predictive of leukaemia risk after adjusting for duration of employment. Duration of employment was strongly associated with an increased risk of leukaemia. Those who had worked for at least 20 years, and were in the highest tertiles of percentage of time spent above 10 and 20V/m, had odds ratios of 10.17 and 8.23, respectively, when compared with those in the lowest tertile. Non-significant elevations in risk were observed between indices of magnetic fields and leukaemia. The results support the hypothesis that electric fields act as a promoting agent in the aetiology of adult leukaemia. Exposure assessment based on alternative indices of electric and magnetic fields should be incorporated into future occupational studies of cancer.
