Influence of polychlorinated biphenyls on the growth of chicken embryos.
Incubation of chicken embryos with either 0.01 or 0.03 ppm polychlorinated biphenyls (PCBs) for 12, 15, or 18 d resulted in a significant decrease in liver and body weight associated with enhanced mortality. Teratological examination revealed an increased frequency of malformations including hydrops, eventration, wry neck, and brevicollis. PCB exposure was also found to produce histologic damage to liver and cutaneous tissue. Our data demonstrate that exposure of chicks to PCBs during development results in a retardation of growth, an increased incidence of malformations, and histopathologic damage.
