Radiofrequency Electromagnetic Radiation

Radiofrequency electromagnetic radiation emitted from Wi-Fi devices is nonionizing radiation. The frequencies used in wireless technology are similar to those applied in mobile telephony. Due to the much lower output power of devices using Wi-Fi compared to mobile phones, the degree of exposure to radiation is also lower. Most of the research on Wi-Fi has been carried out in less favorable or adverse conditions, involving higher power values of devices (peak values instead of average values) and smaller distances of working devices from measuring points. None of the studies conducted so far have indicated that there were the exceedances of the permissible values of radiofrequency electromagnetic radiation contained in the Polish and global legal regulations. Similar to the research related to the impact of mobile telephony on human health, the studies conducted until now focusing on exposure to Wi-Fi are considered ambiguous as they do not give a definitive answer on the possible negative (including carcinogenic) effects on human health. Because of the continuous development of wireless networks, there is a need for further research on this topic. Moreover, due to the high popularity of devices using Wi-Fi among children and adolescents, whose period of exposure to electromagnetic radiation is longer compared to adults, it is necessary to continuously observe these populations and subject them to careful analysis.

The Impact

In recent years, there has been a rapid increase in the number of electromagnetic radiation sources such as mobile phones and base stations of mobile telephony. This radiation has been classified by the International Agency for Research on Cancer as a possible human carcinogen (group 2B). For this reason, many studies have been carried out on the impact of mobile telephony on human health. The largest of the experiments were carried out on animals. Due to the divergent results of many studies, there was no clear answer on the possible carcinogenic effects of this type of radiation on health. Detection of cancer shortly after an exposure is the most difficult task in analyzing the results. Some of the studies require repetition and verification of the results. In the case of negative effects of electromagnetic fields on brain activity, sleep, heart rate, cognitive function and blood pressure, no consistent evidence has been obtained either. In view of the increasing popularity of mobile phones, their location at short distances from the body (mainly the head) and the development of mobile phone technologies (which entails an increase in the number of base stations), further research, especially among young people, is needed. The duration of human exposure to electromagnetic radiation is subject to an increase and only further research can provide an answer on the possible negative effects of mobile phones and base stations.

The Impact

The environment we live in is exposed to the increasing and increasing frequency of electromagnetic radiation in our homes and workplaces. In addition to natural radiation from the sun, radiation sources such as high-voltage transmission lines and powerful radar devices are sources of strong electric and magnetic fields. Increasing the number of portable communication and entertainment devices also increase the human body's exposure to additional electromagnetic radiation. This paper describes the most common effects of low-frequency non-ionizing electromagnetic fields (ELFs), which can cause biological changes, sometimes negative for human health. Different methods and approaches are used to investigate the effect of non-ionizing electromagnetic fields on biological systems. In vitro cell culture studies provide important insights into the underlying mechanisms of biological effects of low radiation levels. It is often not possible to deduce the functional response of a human organism to a particular biological effect. In vivo animal and human studies provide more convincing evidence of possible adverse health effects. There is a problem with the extrapolation of the results obtained from animal experiments to humans. Epidemiological studies provide the most direct information on the risk of adverse effects in humans. However, it is difficult to find good control groups that in all aspects (gender, similar life habits, etc.) fit the exposed groups. Care should be taken in interpreting the results of epidemiological studies, especially if low risk is found, as this may be due to other factors. Epidemiological studies are important for monitoring the impact of new technologies on human health [1].

Radiofrequency Electromagnetic Radiation

Aim of Study: The study was aimed at evaluating the impact of radiofrequency electromagnetic radiation (RF-EMR) from mobile phones on the oestrous cycle and reproductive hormones in female Wistar rats.Methods: Twenty-one Mature female Wistar rats weighing 180 to 250 grams were acclimatized for 2 weeks and divided into control (A), 4hrs (B) and 6hrs (C) groups and were exposed to RE-EMF for a period of 28 days. Oestrous cycle was monitored daily and hormonal level was determined using standardized enzymatic colorimetric methods. One-way analysis of variance was used to compare the mean values of variables among the groups accepting statistical significance at p≤ 0.05.Results: Oestrous cycle was deranged in experimental group compared to the control. Mean serum level of Follicle stimulating hormone (FSH) in control group remained low compared to the exposed groups. Luteinizing hormone (LH) levels in group A were almost double that of the group B and C, while the serum level of Oestrogen was lowest in group A. Progesterone level in the control group was higher than the experimental group.Conclusion: RF EMR showed an adverse effect on the weight and oestrous cycle but the effect on the reproductive hormones is not  significant although the effect appeared to be related to the duration of exposure.

Nutraceuticals have been around for quite some time. As the nomenclature suggests, they are placed somewhere between food (nutra-) and medicine (-ceuticals) in terms of their impact on human health. Researches have focused on the impact of various types of nutraceuticals on health, their efficacy in health promotion and disease prevention, and often on suitable uses of certain categories of nutraceuticals for specific health issues. However, we are still far from utilizing the immense potential of nutraceuticals for benefiting human health in a substantial manner. We review the available scholarly literature regarding the role of nutraceuticals in health promotion, their efficacy in disease prevention and the perception of nutraceuticals' health benefits by consumers. Thereafter we analyze the need for regulation of nutraceuticals and various provisions regarding the same.

The Impact

Background: The persistent dioxins/furans has caused a worldwide concern as they influence the human health. Recent research indicates that nonmaterial may prove effective in the degradation of Dioxins/furans. The nanomaterials are very reactive owing to their large surface area to volume ratio and large number of reactive sites. However, nanotechnology applications face both the challenges and the opportunities to influence the area of environmental protection. Objective: i) To study the impact of oil mediated UV-irradiations on the removal of 2,3,7,8-TCDD, 2,3,7,8-TCDF, OCDD and OCDF in simulated soil samples. ii) To compare the conventional treatment methods with the modern available nanotechniques for the removal of selected Dioxins/furans from soil samples. Methods: The present work has investigated an opportunity of the degradation of tetra and octachlorinated dioxins and furans by using oil mediated UV radiations with subsequent extraction of respective dioxins/furans from soils. The results have been compared with the available nanotechniques. Results: The dioxin congeners in the simulated soil sample showed decrease in concentration with the increase in the exposure time and intensity of UV radiations. The dechlorination of PCDD/Fs using palladized iron has been found to be effective. Conclusion: Both the conventional methods and nanotechnology have a dramatic impact on the removal of Dioxins/furans in contaminated soil. However, the nanotechniques are comparatively costlier and despite the relatively high rates of PCDDs dechlorination by Pd/nFe, small fraction of the dioxins are recalcitrant to degradation over considerable exposure times.
