Evidence for ELF and health effects

Scientific Studies showing Low Frequency Magnetic & Electric fields and Biological Effects:

(1)   Zhou H et. al., 2012, Association between extremely low-frequency electromagnetic fields occupations and amyotrophic lateral sclerosis: a meta-analysis

“Our data suggest a slight but significant amyotrophic lateral sclerosis ALS risk increase among those with job titles related to relatively high levels of ELF-EMFexposure. Since the magnitude of estimated RR was relatively small, we cannot deny the possibility of potential biases at work. Electrical shocks or other unidentified variables associated with electrical occupations, rather than magnetic-field exposure, may be responsible for the observed associations with ALS.”

(2)   Baldi I et. al., 2011, Occupational and residential exposure to electromagnetic fields and risk of brain tumors in adults: a case-control study in Gironde, France

“A nonsignificant increase in risk was found for occupational exposure to electromagnetic fields  [odds ratio (OR = 1.52, 0.92-2.51)]. This increase became significant for meningiomas, especially when considering ELF separately [OR = 3.02; 95 percent confidence interval (95% CI) =1.10-8.25]. The risk of meningioma was also higher in subjects living in the vicinity of power lines (<100 m), even if not significant (OR = 2.99, 95% CI 0.86-10.40). These data suggest that occupational or residential exposure to ELF may play a role in the occurrence of meningioma.”

(3)   Basile A et. al., 2011, Exposure to 50 Hz electromagnetic field raises the levels of the anti-apoptotic protein BAG3 in melanoma cells

“These results confirm the stressful effect of exposure to ELF in human cells, by identifying BAG3 protein as a marker of ELF-induced stress. Furthermore, they suggest that BAG3 induction by ELF may contribute to melanoma cell survival and/or resistance to therapy.”

(4)   Li DK et. al., 2011, Maternal exposure to magnetic fields during pregnancy in relation to the risk of asthma in offspring

“Using the categorical MF level, the results showed a similar dose-response relationship: compared with the children whose mothers had a low MF level (median 24-hour MF level, ≤0.3 mG) during pregnancy, children whose mothers had a high MF level (>2.0 mG) had more than a 3.5-fold increased rate of asthma (aHR, 3.52; 95% CI, 1.68-7.35), while children whose mothers had a medium MF level (>0.3-2.0 mG) had a 74% increased rate of asthma (aHR, 1.74; 95% CI, 0.93-3.25). Our findings provide new epidemiological evidence that high maternal MF levels in pregnancy may increase the risk of asthma in offspring.”

(5)   Wang X et. al., 2011, Occupational and residential exposure to electric and magnetic field and its relationship on acute myeloid leukemia in adults – A Meta-analysis

“Through employing the alternate cut points, stratification by level of exposure or distance and the relation on different ways of exposure, there appeared consistent evidence of increased risk between acute myeloid leukemia in adults and the extremely low frequency-electromagnetic to field exposure.”

(6)   He LH et.al., 2011, Effects of extremely low frequency magnetic field on anxiety level and spatial memory of adult rats

“Chronic ELF MF exposure has anxiogenic effect on rats, and the promoting effects on spatial learning and long-term retention of spatial memory.”

(7)   Fragopoulou A et. al, 2010, Scientific panel on electromagnetic field health risks: consensus points, recommendations, and rationales

“In November, 2009, a scientific panel met in Seletun, Norway, for three days of intensive discussion on existing scientific evidence and public health implications of the unprecedented global exposures to artificial electromagnetic fields (EMF). EMF exposures (static to 300 GHz) result from the use of electric power and from wireless telecommunications technologies for voice and data transmission, energy, security, military and radar use in weather and transportation. The Scientific Panel recognizes that the body of evidence on EMF requires a new approach to protection of public health; the growth and development of the fetus, and of children; and argues for strong preventative actions. New, biologically-based public exposure standards are urgently needed to protect public health worldwide.”

(8)   Garcia AM et. al., 2008, Occupational exposure to extremely low frequency electric and magnetic fields and Alzheimer disease: a meta-analysis

“Available epidemiological evidence suggests an association between occupational exposure to ELF-EMF and AD. However, some limitations affecting the results from this meta-analysis should be considered. More information on relevant duration and time windows of exposure, on biological mechanisms for this potential association and on interactions between electromagnetic fields exposure and established risk factors for AD is needed.”

(9)   Hug K et. al., 2006, Magnetic field exposure and neurodegenerative diseases–recent epidemiological studies

“The epidemiological evidence for an association between occupational exposure to low-frequency electromagnetic fields and the risk of dementia has increased during the last five years. The impact of potential confounders should be evaluated in further studies.”

(10) Kabuto M et. al., 2006, Childhood leukemia and magnetic fields in Japan: a case-control study of childhood leukemia and residential power-frequency magnetic fields in Japan

“Residential power-frequency magnetic fields (MFs) were labeled as a possible human carcinogen by the International Agency for Research on Cancer panel. In response to great public concern, the World Health Organization urged that further epidemiologic studies be conducted in high-exposure areas such as Japan. We conducted a population-based case-control study, which covered areas inhabited by 54% of Japanese children.  Most of the leukemia cases in the highest exposure category had MF levels far above 0.4 microT. Our results provided additional evidence that high MF exposure was associated with a higher risk of childhood leukemia”

(11) Lowenthal RM et. al., 2007, Residential exposure to electric power transmission lines and risk of lymphoproliferative and myeloproliferative disorders: a case-control study

“Although recognizing that this study has limitations, the results raise the possibility that prolonged residence close to high-voltage power lines, especially early in life, may increase the risk of the development of MPD and LPD later.”

(12) Rajkovic V et. al., 2003, Evaluation of rat thyroid gland morphophysiological status after three months exposure to 50 Hz electromagnetic field

“Results of this study demonstrate that after significant morphophysiological changes caused by ELF-EMF exposure thyroid gland recovered morphologically, but not physiologically, during the investigated repair period.”

(13) Wood AW et. al., 1998, Changes in human plasma melatonin profiles in response to 50 Hz magnetic field exposure

“Response to this exposure was compared to sham-exposure (in random order). When exposure preceded onset of rise, a significant delay in onset time relative to sham-exposure of approximately half an hour was observed, with indications (marginally significant) of a reduction in maximum melatonin level. Analysis of distribution of time-delays is consistent with two populations: those individuals who respond (around 20%) and those that do not. Magnetic fields generated by square-wave currents produce more marked reductions in the maximum level when compared to sinusoidal waveforms, but there was no significant difference in onset time.”

(14) Feychting M et. al., 1993, Magnetic fields and cancer in children residing near Swedish high-voltage power lines

“A case-control study was conducted to test the hypothesis that exposure to magnetic fields of the type generated by high-voltage power lines increases cancer incidence in children.  When historical calculations were used as exposure assessment for childhood leukemia with cutoff points at 0.1 and 0.2 microtesla (microT), the estimated relative risk increased over the two exposure levels and was estimated at 2.7 (95% confidence interval (CI) 1.0-6.3) for 0.2 microT and over; p for trend = 0.02.“

(15) Wertheimer N et. al., 1979, Electrical wiring configurations and childhood cancer

“An excess of electrical wiring configurations suggestive of high current-flow was noted in Colorado in 1976-1977 near the homes of children who developed cancer, as compared to the homes of control children. The finding was strongest for children who had spent their entire lives at the same address, and it appeared to be dose-related. It did not seem to be an artifact of neighborhood, street congestion, social class, or family structure. The reason for the correlation is uncertain; possible effects of current in the water pipes or of AC magnetic fields are suggested.”
