Effects of mobile phone radiofrequency on the structure and function of the normal human hemoglobin. med./bio.

Published in: Int J Biol Macromol 2009; 44 (3): 278-285

Aim of study (acc. to author)

To study the effect of mobile phone radiofrequency (910 MHz and 940 MHz) on the structure and function of hemoglobin, because of the importance of hemoglobin as a sole oxygen transporter in blood.

  • during exposure
  • after exposure

Main outcome of study (acc. to author)

The data indicated that mobile phone electromagnetic fields (both frequencies) altered oxygen affinity and tertiary structure of hemoglobin. Furthermore, the decrease of oxygen affinity of hemoglobin corresponded to the electromagnetic field intensity and time of exposure.
