Abstract:

Groups of 10 male rats were exposed to vertical 60 Hz electric fields of 0, 50, 500, 1000 Vm for 30d. Duplicate tests were run for 0, 500, 1000 Vm. Subjects lived in a plastic test facility for 7d prior and for 7d following exposure. Body weight, water consumption, food consumption, urine output and general activity were measured. Urine from 6 animals was obtained by fraction collection all samples for selected days were tested by atomic absorption for K, Na and Ca. Following the experiment, subjects from 500 and 1000 Vm conditions were sacrificed thyroid and adrenal tissues were weighed intracardiac blood samples were fully analyzed. Most measures showed no statistically significant differences between experimentals and controls or between experimentals exposed to the various field strengths. Two activity measurements showed field effects 1 size and duration of nighttime activity bout was reduced in the 1000 Vm condition, from the other conditions during initial exposure 2 relative activity during the 0900-1000 period was consistently but not significantly greater in the 1000 Vm condition than the other conditions throughout exposure. Urine electrolyte data did not suggest altered steroid excretion as a result of exposure. Author
