DOSE RELATED SHIFTS IN THE DEVELOPMENTAL PROGRESS OF CHICK EMBRYOS EXPOSED TO MOBILE PHONE INDUCED ELECTROMAGNETIC FIELDS
Abstract
Background: The possible adverse effects of Electromagnetic Fields (EMFs) emitted from mobilephones present a major public concern today. Some studies indicate EMFs effects on genes, free
radical production, immunological and carcinogenic effects. On the other hand there are studies
which do not support the hypothesis of any biological impacts of EMFs. This study was designed to
observe the effects of mobile phone induced EMFs on survival and general growth and development
of chick embryo, investigating dose-response relationship if any. Methods: This was an
experimental study in which developing chick embryos were exposed to different doses of mobile
phone induced EMFs. For this purpose a mobile phone was placed in the incubator in the centre of
fertilised eggs in silent ringing mode and was '˜rung' upon from any other line or cell phone. After
incubation for 10 or 15 days the eggs were opened and the developmental mile-stones of the
surviving embryos were compared with the non exposed subgroup. Results: EMFs exposure
significantly decreased the survivability of the chick embryos. The lower doses of EMFs caused
growth retardation. However, this effect of growth retardation reallocated to partial growth
enhancement on increasing the dose of EMFs and shifted over to definite growth enhancement on
further raising the dose. Conclusion: There is an adverse effect of EMFs exposure on embryo
survivability. Chick embryos developmental process is influenced by EMFs. However, these effects
are variable depending upon the dose of EMFs exposure.
