A review on residential exposure to electromagnetic fields from overhead power lines : electrification as a health burden in rural communities

Abstract: Electrification has improved millions of lives over the years. With the benefit of electricity comes the emission of electromagnetic fields (EMFs) from power lines, substations, electrical home appliances and railways. There have been studies done to associate exposure to EMFs with the development of health effects such as cancer and transient biological effects. The aim of this paper is to provide discourse on the association between EMFs and cancer, not excluding other severe health effects such as cognitive impairment and preterm labor in pregnant women. In this paper, google scholar, science direct and PubMed were used to search for literature. Out of thirty articles, fifteen were selected and used to compile this paper. These articles revealed that studies in the past have found conflicting results from research conducted globally. Eight articles out of the fifteen found a link between exposure to EMFs and leukemia as well as impaired neurobehavioral function in children. Six articles found a statistically insignificant association, with one article being inconclusive. World Health Organization (WHO) found a link between childhood Leukemia and EMFs, bringing it into the attention for more research to be done to confirm this association. Based on the evidence, epidemiological studies need to be done and address the data scarcity relating to EMFs from power lines; especially in the South African context
