Oxidative stress is one of the possible negative effects of high frequency electromagnetic fields. The reported study, in particular, investigates the effect of 2.4 GHz Wi-Fi router electromagnetic radiation on the cytoplasmic antioxidant enzyme superoxide dismutase 1 in the brain of the honeybee (Apis mellifera L.). The honeybee, the main pollinator of agricultural crops, is especially sensitive to electromagnetic fields due to the need to use it in its in the natural conditions in the process of life. The honeybees were exposed to radiation for 1 hour. The control honeybees were not exposed to radiation. Next, the brain was removed and, using immunohistochemical staining and fluorescence microscopy, the distribution and content of superoxide dismutase 1 were assessed on sections of the honeybee brain in the region of mushroom bodies — a structures responsible for learning and memory. It was found that after 1 hour exposure there is a decrease in the content of superoxide dismutase-1 level compared to the control group.
The obtained results point at a possible disturbance of antioxidant protection in the nervous tissue of bees under the influence of 2.4 GHz high-frequency electromagnetic radiation. For a more complete understanding of the mechanisms of the influence of electromagnetic radiation on the honeybee central nervous system, further research is needed.
