Nieuwe studie: hypothese over de meetbaarheid van elektrogevoeligheid

Gegevens

Gepubliceerd: vrijdag 15 november 2013 09:47

PubMed - "Electromagnetic hypersensitivity (EHS) is an ill-defined term to describe the fact that people who experience health symptoms in the vicinity of electromagnetic fields (EMFs) regard them as causal for their complaints. Up to now most scientists assume a psychological cause for the suffering of electromagnetic hypersensitive individuals. This paper addresses reasons why most provocation studies could not find any association between EMF exposure and EHS and presents a hypothesis on diagnosis and differentiation of this condition. Simultaneous recordings of heart rate variability, microcirculation and electric skin potentials are used for classification of EHS. Thus, it could be possible to distinguish "genuine" electromagnetic hypersensitive individuals from those who suffer from other conditions."

Radiation from wireless technology affects the blood, the heart, and the autonomic nervous system

Exposure to electrosmog generated by electric, electronic, and wireless technology is accelerating to the point that a portion of the population is experiencing adverse reactions when they are exposed. The symptoms of electrohypersensitivity (EHS), best described as rapid aging syndrome, experienced by adults and children resemble symptoms experienced by radar operators in the 1940s to the 1960s and are well described in the literature. An increasingly common response includes clumping (rouleau formation) of the red blood cells, heart palpitations, pain or pressure in the chest accompanied by anxiety, and an upregulation of the sympathetic nervous system coincident with a downregulation of the parasympathetic nervous system typical of the "fight-or-flight" response. Provocation studies presented in this article demonstrate that the response to electrosmog is physiologic and not psychosomatic. Those who experience prolonged and severe EHS may develop psychologic problems as a consequence of their inability to work, their limited ability to travel in our highly technologic environment, and the social stigma that their symptoms are imagined rather than real.

West Australian school bans phones at breaks

the West Australian/EMFachts Consultancy - Prestigious girls' school Penrhos College has banned students from using mobile phones during their lunch and recess breaks because of concerns students are losing the art of conversation.

Principal Meg Melville said, even though girls were sitting in groups during breaks, teachers had become aware students were texting their friends instead of talking to each other. "We decided we wanted to really encourage them during their break times at school to have conversations with one another, face-to-face," she said.

Mrs Melville said technology was embedded in the curriculum and mobile phones had become an important part of that. But it was just as important for students to develop conversation skills such as understanding the nuances conveyed by people's reactions and body language.

Drosophila oogenesis as a bio-marker responding to EMF sources

Link naar het artikel van Alasdair Philips (Powerwacth UK) met afbeeldingen.

Lukas Margaritis and colleagues have produced a superb new research paper showing significant negative effects of a range of everyday RF devices on fruit-fly fertility.

In my opinion, this large (25 page) paper is one of the best examples of a good scientific paper into EMF/RF effects on life processes that I have ever seen. It is well set-out and, most unusually for biological investigative papers, it gives excellent, high-quality, detailed measurements of the signal strengths, frequencies and waveforms of the RF signals to which the fruit flies were exposed.

They used a GSM (2G) handset, a DECT cordless phone base-unit and also a DECT handset, WiFi, a low-power Bluetooth adapter, 2.4 GHz WiFi and a number of other devices.

They write "All EMF sources used created statistically significant effects regarding fecundity and cell death-apoptosis induction, even at very low intensity levels (0.3 V/m bluetooth radiation), well below ICNIRP's guidelines, suggesting that Drosophila oogenesis system is suitable to be used as a biomarker for exploring potential EMF bioactivity."

Overproduction of free radical species in embryonal cells exposed to low intensity radiofrequency radiation

Gegevens

Gepubliceerd: maandag 21 oktober 2013 21:14

Conclusion: Exposure of developing quail embryos to extremely low intensity RF-EMR of GSM 900 MHz during at least one hundred and fifty-eight hours leads to a significant overproduction of free radicals/reactive oxygen species and oxidative damage of DNA in embryo cells. These oxidative changes may lead to pathologies up to oncogenic transformation of cells.

Powerwatch.org.uk - RF-EMF emissions from wireless phones are class 1 human carcinogens

Using the long-established and respected Bradford Hill criteria for assessing causality, this paper shows that RF-EMF exposure from mobile (and cordless) phones should be regarded as an IARC class 1 human carcinogen (cancer causing agent). Current guidelines for exposure need to be urgently revised.

Wi-Fi papers

via WiFi in Schools UK:

A list of papers finding effects of Wi-Fi or 2.4GHz signals below 16V/m can be found here: http://wifiinschools.org.uk/30.html.

A pdf file of first pages of these papers can be found here: http://wifiinschools.org.uk/resources/Wi-Fi+papers.pdf.  It can be useful to print off the first pages of papers to illustrate to schools or parents that there is published evidence of adverse effects of Wi-Fi / 2.4GHz signals.

Amongst the references is one form Margaritis et al (http://www.ncbi.nlm.nih.gov/pubmed/23915130), which found that that a mobile phone,  DECT wireless base, DECT wireless handset, mobile phone-DECT handset combination, Wi-Fi, blue tooth, 92.8 MHz FM, baby monitor and a microwave oven all damaged fertility of fruit flies, even at 0.3V/m.  They decreased reproductive capacity, with a decrease in numbers of pupae, and increased DNA fragmentation in ovarian follicles (increased apoptotic cells).  This might be relevant for declining numbers of other insects, and demonstrates another biological effect at low RF exposures.

The paper by Markov and Grigoriev, 2013, on Wi-Fi is also worth looking at: http://www.avaate.org/IMG/pdf/Wi-fi_Technology_-_An_Uncontrolled_Global_Experiment_on_the_Health_of_Mankind_-_Marko_Markov_Yuri_G._Grigoriev.pdf

Studie: Using the Hill viewpoints from 1965 for evaluating strengths of evidence of the risk for brain tumors associated with use of mobile and cordless phones

Gegevens

Gepubliceerd: vrijdag 11 oktober 2013 07:47

Results: The criteria on strength, consistency, specificity, temporality, and biologic gradient for evidence of increased risk for glioma and acoustic neuroma were fulfilled. Additional evidence came from plausibility and analogy based on laboratory studies. Regarding coherence, several studies show increasing incidence of brain tumors, especially in the most exposed area. Support for the experiment came from antioxidants that can alleviate the generation of reactive oxygen species involved in biologic effects, although a direct mechanism for brain tumor carcinogenesis has not been shown. In addition, the finding of no increased risk for brain tumors in subjects using the mobile phone only in a car with an external antenna is supportive evidence. Hill did not consider all the needed nine viewpoints to be essential requirements.

Conclusion: Based on the Hill criteria, glioma and acoustic neuroma should be considered to be caused by RF-EMF emissions from wireless phones and regarded as carcinogenic to humans, classifying it as group 1 according to the IARC classification. Current guidelines for exposure need to be urgently revised.
