5 GHZ Wi Fi Effects on Escherichia Coli, Caenorhabditis Elegans and Human Neuroblastoma Cells

Abstract

The use of 5 GHz Wi-Fi has spread and potential effects on microorganisms and human health are still under investigation. To investigate the possible effects for that, experiments were performed using three different microorganisms, Escherichia coli, SH-SY5Y human neuroblastoma cells and Caernohabditis elegans. The maximum allowed temperature for the Wi-Fi Access Point (AP) was considered in the measurement setup in order not to harm the internal circuitry of the router which can result impact the performance of the router. Suspension turbidity, optical density measurements and simultaneous counting of E. coli were performed. It was observed that 5 GHz Wi-Fi exposure slow down the E. coli growth rate at the same temperature conditions with sham exposed groups especially after the first 6 h. 5 GHz Wi-Fi induced decrease in cell viability remarkably for the cells seeded at densities 20,40, 100 (×10 3) and viability values were varied between 20 and 30%. C. elegans which is a nematode, plays key role in nutrient cycling and soil fertilization was affected by the radiation and egg-laying rates changed by 27.49%.
