Abstract

During the last few decades, worldwide intensive implementation of GSM mobile communication systems has occurred. Recent epidemiological studies raised concerns about potential hazards of long-term microwave exposure for human health. We aimed at assessment of biological effects of microwave emitted by commercial cell phone using developing bird embryo as a model. Embryos of Japanese Quails were exposed in ovo to GSM 900 MHz cellular phone radiation during initial 38 h of brooding or alternatively during 158 h (120 h before brooding plus initial 38 h of brooding) discontinuously with 48 sec ON followed by 12 sec OFF intervals. Maximum intensity of incident radiation on the egg’s surface was 0,2 µW/cm2. A number of differentiated somiteswere assessed microscopically. Possible DNA damage evoked by irradiation was assessed by an alkaline comet assay. Exposure to radiation from GSM 900 MHz cellular phone led to a significantly altered number of differentiated somites. In embryos irradiated during 38 h the number of differentiated somitesincreased (p<0,001), while in embryos irradiated during 158 h this number decreased (p<0.05). The lower duration of exposure led to significant (p<0.001) decrease in a level of DNA stand breaks in cells of 38-h embryos, while the higher duration of exposure resulted in a significant (p<0.001) increase in DNA damage as compared to the control.
