چکیده انگلیسی
During the last few decades there has been an enormous increase in the usage of cell phones as these are one of the most convenient gadgets and provide excellent mode of communication without evoking any hindrance to movement. However, these are significantly adding to the electromagnetic field radiations (EMF-r) in the environment and thus, are required to be analysed for their impacts on living beings. The present study investigated the role of cell phone EMF-r in inciting oxidative damage in onion (Allium cepa) roots at a frequency of 2100Â MHz. Onion roots were exposed to continuous wave homogenous EMF-r for 1, 2 and 4Â h for single day and generation of reactive oxygen species (ROS) in terms of malondialdehyde (MDA), hydrogen peroxide (H2O2) and superoxide anion (O2â) content and changes in the activities of antioxidant enzymes- superoxide dismutases (SOD) and catalases (CAT) were measured. The results showed that EMF-r exposure enhanced the content of MDA, H2O2 and O2â. Also, there was an upregulation in the activity of antioxidant enzymesâ SOD and CATâ in onion roots. The study concluded that 2100Â MHz cell phone EMF-r incite oxidative damage in onion roots by altering the oxidative metabolism.
