Abstract

Mice were allowed to mate, gestate, deliver and rear their offspring for 3 successive generations while being continuously exposed to 60 Hz electric fields. Mice exposed to vertical electric fields exhibited decreased body weights at 35 days postpartum and increased mortality rates for 3 successive generations. Mice exposed to horizontal electric fields exhibited decreased body weights for 2 successive generations.

Main findings

Across three successive generations continuously exposed to 60 Hz electric fields, mice exposed to vertical fields had decreased body weights at 35 days postpartum and increased mortality rates for all three generations. Mice exposed to horizontal fields had decreased body weights for two successive generations.
