Effects of Electromagnetic Fields on the Microbial Load of Waste Water Samples from Selected Industries in Akure Metropolis

Wastewater is any water that has been adversely affected in quality by anthropogenic influence which can serve as habitat for pathogenic microbes and can constitute to health hazard of the populace. The present study was designed to enumerate and identify microorganisms in wastewaters and to investigate the effect of Electromagnetic Field (EMF) on the populations and identities of bacteria in the wastewaters from selected industries in Akure Metropolis. Wastewater samples were collected from two different industries in Akure Metropolis. The waste water samples were subjected to microbiological analyses before and after exposure to Electromagnetic field (EMF) at 1150nT, 1310nT, 3000nT, 5000nT. The presence of some bacteria in the waste water collected from different companies showed their occurrence at different hours during the treatment of the wastewater sample with different EMF strength. It was observed that at the early part (hours) of the experiment the heavy presence of microbes were seen but as the experiment progresses the microbial population were observed been reduced. It is therefore recommended that wastewater from industries should be treated with EMF before discharging them to the other water bodies so as to avoid contamination. This will help reduce microbial population that constitute a serious hazard to public health. And could also help protect other life forms inhabiting the water body and thus guard against ecological imbalance of the microbiota
