Impact of chronic exposure to static, high voltage electric field generated nearby HVDC transmission lines on behavior of rats

The impact of chronic, whole-body exposure to static electric field with physical parameters generated nearby HVDC transmission lines on behavior in rats was investigated. Rats were exposed for 56 consecutive days (8 hours daily) to static electric field with intensity of 16 and 25 kV/m or sham-exposed, respectively. Before the beginning and then in particular days of the exposure cycle an evaluation of a locomotor activity, exploratory activity, space learning and irritability was made. Only a transient reduction of locomotor activity in the initial phase of exposure cycle without any effect on exploratory activity, space learning and irritability was observed.
