A teratological assessment was performed using rats that were exposed to an alternating magnetic field. The magnetic field had a sawtooth waveform similar to that produced by video display terminals (VDTs). Female rats were exposed 2 weeks prior to and throughout pregnancy at a rate of 7 h/day. Three intensities of magnetic field (5.7, 23 or 66 microT) were(More)
This study was designed to provide information on the subchronic toxicity of octachlorostyrene (OCS), a demonstrated environmental pollutant in fish from the Great Lakes of North America and the Norwegian coast in Europe. Groups of 15 male and 15 female rats were administered OCS mixed in the diet at 0.05, 0.5, 5.0, 50, or 500 ppm for 13 weeks. Increased(More)
