A Correlation of Extracellular Superoxide Dismutase Activity with Peroxynitrite Concentration in Inhabitants around Mobile Phones Base-Stations


Potential health effects of radiofrequency radiation emitted from mobile phones base-stations (MPBS) have been a topic of scientific interest since the tree late decades. Earlier studies have been reported a relation of radio frequency radiation emitted from MPBS with free radical formation within the cell such as reactive oxygen species (ROS).Here, protein concentration, extracellular superoxide dismutase (EC-SOD) activity and peroxynitrite (ONOO-) concentration were measured spectrophotometrically in blood plasma of inhabitants -for more than three years-around MPBS (250 m2), then the correlation of EC-SOD activity with ONOO- concentration was investigated. The results were compared with volunteers who reside faraway from MPBS as a control group. Our results revealed presence of a significant increase in total protein concentration, EC-SOD activity and ONOO- concentration (p< 0.05) in comparison with that of control group. In addition, the results indicate there is no high correlation between EC-SOD activities with ONOO- concentrations. The results proved that the long exposure to emitted radiations from MPBS at domestic level has negative impact on human health due to increase the dangerous oxidant radicals which can cause many diseases and aging.
