electromagnetic radiation environmental pollution and health

Is electromagnetic radiation really safe? , Feychting M, Möller M et al. Animal studies are being used to look for effects impacting more complex physiologies that are similar to humans. A However, whether, and by whom, even very low cost actions should be recommended in situations with such weak scientific support for the existence of a risk is currently the topic of intense discussions. [34] Focused RF radiation can also cause burns on the skin or cataracts to form in the eyes. [14][15], Fundamental mechanisms of the interaction between biological material and electromagnetic fields at non-thermal levels are not fully understood. However, quite a number of other applications also employ fields in the range below 300 GHz. JE L To date, half a dozen epidemiological studies on mobile phone users have been published—with predominantly negative findings. Electromagnetic radiation emitted by cell phone towers is a form of environmental pollution and is a new health hazard, especially to children and patients. An inherent problem in these studies that remains to be solved is exposure assessment around base stations25. The last quarter of the twentieth century saw a dramatic increase in the number of devices emitting non-ionizing radiation in all segments of society, which resulted in an elevation of health concerns by researchers and clinicians, and an associated interest in government regulation for safety purposes. It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. After 30 years of extensive study, science has yet to confirm a health risk from exposure to low-level fields. The fields are invisible; they represent new technology; power line, base station and other sources of exposure are uncontrollable by the exposed individual; for many of the exposure sources, the exposed subject has no direct use of the exposure source. Electromagnetic waves at low frequencies are referred to as electromagnetic fields and those at very high frequencies are called electromagnetic radiations 1,2). A pooled analysis of magnetic fields and childhood leukaemia. [22], Shortwave (1.6 to 30 MHz) diathermy can be used as a therapeutic technique for its analgesic effect and deep muscle relaxation, but has largely been replaced by ultrasound. At the same time, the exposure level above which effects are seen has been pushed upwards, implying that only a small proportion of homes are exposed at those levels. Hardell L The physical quantity that is used in this context is the specific absorption rate (SAR), measured in W/kg. Although the implications by many were considered implausible, and despite several methodological problems in the study, that work has been followed by several attempts to replicate the findings. [43], Ultraviolet light, specifically UV-B, has been shown to cause cataracts and there is some evidence that sunglasses worn at an early age can slow its development in later life. The FCC has restricted the frequencies allowed for medical treatment, and most machines in the US use 27.12 MHz. As a consequence, such fields essentially pass through the body without depositing any energy. This presents decision makers with several dilemmas. Chances are you’re probably sitting in an electromagnetic field (EMF) at this very moment. A new paper in the Lancet assesses the impact of Planetary Electromagnetic Pollution. At sufficiently high flux levels, various bands of electromagnetic radiation have been found to cause deleterious health effects in people. The other group of studies asks subjects in case-control studies about their phone use17–20. [38], Another important factor is the distance between the worker and the source of radiation. S However, extensive research activities are ongoing and much more data will be available in the near future. As a consequence, the epidemiological evidence stands alone. , Loughlin JE, Rothman KJ. At the same time everyone would agree that modern society is inconceivable without electricity. The studies have generally been of increasing methodological strengths, particularly with respect to assessment of magnetic field exposure but also with respect to selection bias and other methodological aspects. The initial lesions and edema will disappear after several weeks, but may leave behind a permanent reduction in visual acuity.[39]. , Feychting M. Re: Use of cellular phones and the risk of brain tumours: a case-control study [letter]. To date, close to 20 studies on childhood cancer and residential exposure to ELF fields have been published3. The technique only heats tissues that are good electrical conductors, such as blood vessels and muscle. Glassblower's cataract is an example of a heat injury that damages the anterior lens capsule among unprotected glass and iron workers. The dilemma is that very few people are exposed at high levels and that the disease for which there is the hardest evidence is very rare. The strongest evidence for health risks is from exposure to fields generated in connection with use of electric power. However, recall bias is always a concern in such studies. Despite intense efforts, this has not resulted in the detection of any new mechanisms of interaction between ELF fields and the human body beyond the induction of electric current, nor a strong candidate for such a mechanism. The current scientific situation is one of uncertainty and it is often pointed out that the existence of risks cannot be excluded. A particular issue is whether to recommend that children in particular should restrict their use. The Journey of pollutants to the brain 5. Inskip For example, touching or standing around an antenna while a high-power transmitter is in operation can cause severe burns. “As the Planetary Health Alliance moves forward after a productive second annual meeting, a discussion on the rapid global proliferation of artificial electromagnetic fields would now be apt. [4] These can deliver an electric shock to persons or animals. According to scientists, when the charged particles from the sun come in contact with the magnetic field of the Earth, they produce these lights. The electromagnetic spectrum encompasses a wide variety of electromagnetic fields, including static fields, radio frequency fields, UV radiation, visible light and X-ray radiation. A To date, no adverse health effects have been established as being caused by mobile phone use. Interest has prevailed in relation to breast cancer, which remains a focus of attention. The internal SAR cannot be measured directly inside the body, but is established based on models and theoretical calculations. Cancer incidence near radio and television transmitters in Great Britain. Based on the combined control groups in the pooled analysis, this percentage was estimated at less than 1%, and considerably less in the European subset. However, a recently completed large study with refined occupational exposure information and oestrogen status data for the cases was entirely negative and this is likely to affect the interest in this research track5. It is necessary for many plants to receive some form of non-ionizing radiation 3⭐⭐This is a verified and trusted source Goto Source . Learn how your health and well-being are affected and find out what you can do to protect yourself. In the case of arc welding, infrared radiation decreases rapidly as a function of distance, so that farther than three feet away from where welding takes place, it does not pose an ocular hazard anymore but, ultraviolet radiation still does. We refer to this as RF (radiofrequency). Sastre The current density induced in the body is a direct consequence of the external magnetic field flux density; this is the reason why such fields are typically characterized by their μT-level. [citation needed] The federal communications commission begun to check the findings.[33]. A Now it’s too late. Therefore microwave and radiofrequency pollution constitutes a potential cause for the decline of animal populations and deterioration of health of plants living near phone masts. This technology typically uses frequencies from 450 up 2500 MHz, although new technology will extend this band upwards. Despite these efforts, however, results have been inconclusive. Practically every new invention adds something to electromagnetic radiation pollution. Radio frequency (RF) energy at power density levels of 1–10 mW/cm2 or higher can cause measurable heating of tissues. Due to the widespread use of these techniques and the very prevalent exposure to some of the types of field involved, even a weak association with disease risk could have strong impacts on public health. The Board has banned new cellular antennas from school lands. In parallel with the epidemiological research, extensive in vivo and in vitro research has also been carried out. Due to potentially catastrophic losses and high clean up costs, product liability insurance contracts frequently exclude, whether partially or completely, the insured’s liability for asbestos, pollution and contamination, radiation and electromagnetic fields. The first few of these replications addressed a variety of cancer types and also total cancer, but later studies have increasingly focused on childhood leukaemia. Electromagnetic Radiation and the Reduction of Health Risks Theme: Healthy and Sustainable Cities The meeting will have the theme “Healthy and Sustainable Cities” and aims to provide visibility, disseminate knowledge and draw attention to the theme of Electromagnetic Pollution, ways of protecting and reducing risks to health and social vulnerability. [30] Studies during the 1960s in Europe and Russia claimed to show effects on humans, especially the nervous system, from low energy RF radiation; the studies were disputed at the time. We declare no competing interests. ", Characterization of 60GHz Millimeter-Wave Focusing Beam for Living-Body Exposure Experiments, Tokyo Institute of Technology, Masaki KOUZAI et al., 2009, "Cutaneous effects of infrared radiation: from clinical observations to molecular response mechanisms", "Biological effects and medical applications of infrared radiation", "An Overview of the LED and Laser Classification System in EN 60825-1 and IEC 60825-1", "What is the minimum safe distance from the welding arc above which there is no risk of eye damage? It is well known that exposure to strong fields can result in acute effects, such as burns; the mechanisms behind such effects are well established. Electromagnetic pollution has effects on human health but is uncommonly considered in present times despite the fact we essentially expose ourselves to it on a daily basis. environmental pollution health effects of electromagnetic radiations from antennae of telecommunication masts erected near residential and educational facilities in enugu, nigeria [37] Short-term exposure can be beneficial (activating protective responses), while prolonged exposure can lead to photoaging. Possible effects of Electromagnetic Fields (EMF) on Human Health 2 About the Scientific Committees Three independent non-food Scientific Committees provide the Commission with the scientific advice it needs when preparing policy and proposals relating to consumer safety, public health and the environment. United States Military Standard 464A (MIL-STD-464A) mandates assessment of HERO in a system, but USN document OD 30393 provides design principles and practices for controlling electromagnetic hazards to ordnance. Electromagnetic fields (EMF) are ubiquitous in modern society. RF radiation and ELF-EMF exposures are classified as a possible human carcinogen, Group 2B. Cause-specific mortality in cellular telephone users. Such a recommendation would not be based on scientific data specifically pointing towards children being at risk, but rather on some common understanding that children are more sensitive because they are still developing, perhaps combined with the moral concept that one should be more careful with children. Chemical pollution in bodies of water contributes to illnesses. Electromagnetic fields are associated with several of the factors that are known to produce public concern. [8], The designation of mobile phone signals as "possibly carcinogenic to humans" by the World Health Organization (WHO) (e.g. DA The actual field levels that people encounter in connection with mobile phone use produce SAR values below the basic restrictions, although of the same order of magnitude. Monitoring Electromagnetic Radiation Emissions in Buildings and Developing Strategies for Improved Indoor Environmental Quality Health Phys . Auvinen The fields from base stations that people experience, on the other hand, are much weaker; they are in fact several orders of magnitude below the guideline levels. Selvin There is, however, also a concern that long-term exposure to weak fields might have health effects due to an as-yet unknown mechanism. Rothman Therefore all living creatures including plants, microbes, animals and humans are environmental indicators of exposure to electromagnetic radiation. , Tarone RE, Hatch EE, Wilcosky TC, Shapiro WR, Selker RG, Fine HA, Black PM, Loeffler JS, Linet MS. Cellular-telephone use and brain tumors. A report linking childhood cancer mortality to the presence of power lines in the near proximity to the children’s homes about 25 years ago spurred the interest in power frequency fields1. H [46][47], Prolonged exposure to ultraviolet radiation from the sun can lead to melanoma and other skin malignancies. While these fields differ with respect to strengths and physical characteristics, they all give rise to concern among those exposed about the possibility of health risks. *FREE* shipping on qualifying offers. C These experiments were followed by a utility worker study showing that chronic heart disease mortality was not associated with ELF exposure but that arrhythmia and myocardial infarction mortality was7. Occupational magnetic field exposure and cardiovascular mortality in a cohort of electric utility workers. They occur in connection with use of electric power, electronic surveillance systems and various types of wireless communications. This renders the study uninformative from the substantive point of view, although it has been important for methodological reasons15,16. NA To assess the overall evidence, a pooled analysis was carried out4 based on primary data from the sub group of nine studies fulfilling certain quality criteria. Photo : Alistair McIntyre, Pixabay. Existing exposure guidelines are expressed in terms of so-called basic restrictions and primarily aim to prevent neurological effects by restricting the internal current density2.

Just as for ELF fields, the in vivo and in vitro research has been unable so far to come up with results that convincingly show the presence of some biological effect from exposure to RF fields other than heating. Cooper These lights can be observed at the north and south poles of the Earth in the most magnificent colors. The interest originates to no small extent from the early epidemiological study by Wertheimer and Leeper1. The so-called Stewart report has a comprehensive review of the RF research10.
