Extremely Low Frequency Electric and Magnetic Fields in Domestic Birds.

Abstract

ELF magnetic and electric fields were maintained at constant levels of 45, 60, or 75 Hz and at magnetic field intensities of 1, 5, 8, or 30 gauss or electric field intensities of 1, 10, or 3600 volts per meter for continuous exposure of chick embryo cells (in vitro), chick embryos during incubation, and developing chicks up to four weeks of age. Responses were evaluated in terms of: (1) embryo cell growth rate (in vitro); (2) embryo mortality before, during, and after incubation; (3) early development and gross behavior of the chick; (4) memory consolidation of the neo-nate chick; (5) growth rate of chicks; (6) embryonic growth and CO2 production; (7) social behavior in adult birds. Chicken embryo cell growth was inhibited when incubated in a magnetic field of 1, 5, or 8 gauss at 60 Hz, in an electric field of 1 or 10 volts per meter at 60 Hz, or in an electric field of 1 volts per meter at 75 Hz. However, an electric field of 10 volts per meter at 75 Hz appeared to accelerate growth of such cells.
