Epidemiological and toxicological studies have shown no statistically significant association <br /> or weak associations between MF exposure and health risks. Public health professionals have also <br /> investigated the possible impact of exposure to EMF upon human health for the past several decades. <br /> ' While the general consensus is that electric fields pose no risk to humans, the question of whether <br /> exposure to magnetic fields can cause biological responses or health effects continues to be debated. <br /> ' In 1999, the National Institute of Environmental Health Sciences ("NIEHS") issued its final report <br /> on "Health Effects from Exposure to Power-Line Frequency Electric and Magnetic Fields" in <br /> response to the Energy Policy Act of 1992. The NIEHS concluded that the scientific evidence <br /> ' linking MF exposures with health risks is weak and that this finding does not warrant aggressive <br /> regulatory concern. However, because of the weak scientific evidence that supports some association <br /> between MFs and health effects and the common exposure to electricity in the United States, <br /> ' passive regulatory action, such as providing public education on reducing exposures,is warranted. <br /> In 2007, the World Health Organization ("WHO") concluded a review of the health implications of <br /> ' electromagnetic fields. In this report, the WHO stated: <br /> Uncertainties in the hazard assessment [of epidemiological studies] include the role <br /> ' that control selection bias and exposure misclassification might have on the observed <br /> relationship between magnetic fields and childhood leukemia. In addition, virtually <br /> all of the laboratory evidence and the mechanistic evidence fail to support a <br /> relationship between low-level ELF magnetic fields and changes in biological <br /> function or disease status. Thus,on balance, the evidence is not strong enough to be <br /> considered causal, but sufficiently strong to remain a concern.
