The influence of low level electromagnetic fields on developing organisms has been the focus of many reports. However, there have been few, if any, investigations using VDT monitors found in the marketplace. Three custom-designed chick egg incubators constructed solely of wood and plastic were built on site. Temperature between the incubators was maintained at 36±0.5°C. IBM color monitors (#8512) or a tungsten light were placed 20 inches above fertile eggs. Immediately before and after each experiment readings of DC, ELF and VLF were obtained at the area where the eggs were exposed. In addition, a device designed to protect the eggs from possible deleterious effects of the VDTs was tested. The experimental design included three groups tested three times in each of three incubators. For each test run, twenty eggs/groups were exposed continuously for five days and examined for eye, brain, limb or body abnormalities. The three groups were: a sham control group (tungsten light at the same lux value), a VDT group and a VDT plus protective device group. Using a blind scoring system, preliminary results indicate a possible increase in the percentage of abnormal embryos with VDT exposure when compared to the sham control, which is reduced with the protective device. However, it is cautioned that these experiments are ongoing; statistical analyses of the data will be performed when all testing has been completed.
