We are all exposed to electromagnetic fields from electrical appliances, electric power transmission lines, distribution lines and power substations. This study was focused on investigating the possible risks to human health due to exposure to extremely low frequency varying magnetic fields from 330 kV, 132 kV, 33 kV and 11kV power lines in southeastern Nigeria. To determine the risks, a magnetic field meter was used to take measurements of magnetic flux from these power lines. From which, the induced current density due to exposure to varying magnetic fields was obtained using a model of the human body known as the prolate spheroid model. The maximum mean magnetic field and current density induced as obtained from the study were 4.790 µT and 0.04214 mA/m², which were obtained from the 330 kV power line. The study results are well below the reference levels of the International Commission for Non-Ionizing Radiation Protection, which are used for comparison, indicating that there is very low exposure risk to people living near these electric power transmission lines.

<span lang="EN-GB">This work is a review on previous research and studies on the solar disturbance activities and faults that occur on the electric power transmission line. Research has shown that low latitude regions could also be affected by solar disturbance events. The effects of these events on earth are considerable and may cause electric power transmission failure. Geomagnetically induced current is one of the ground impacts to the transmission line, which may cause fault or disturbance and consequently power system failure. Solar disturbance data from magnetometers and electric power transmission line fault data from a digital fault recorder are reviewed in this work. These data would be valuable in determining the characteristics and effects of solar disturbances on Malaysia’s electric power transmission lines.</span>

AbstractThe processes of supplying natural gas are accompanied by significant losses. In this regard, the complex problem of minimizing losses and improving the efficiency of energy use is very relevant. Steel pipelines for transportation of oil and gas often cross the tracks or are located parallel to the lines of electric power transmission lines of alternating current. Most dangerous from the corrosive point of view of the combination of the chemical composition of the soil electrolyte and the vagal current density were established.

Este estudo visa apresentar como a educação ambiental tem sido utilizada como um recurso de grande importância na área de consultoria e assessoria ambiental, voltado a mitigação de impactos ambientais gerados por empreendimentos do setor energético. Primeiramente, neste estudo foi realizada uma contextualização acerca do processo de licenciamento ambiental vigente no Brasil, bem como das primeiras legislações ambientais responsáveis por regularizar a utilização dos recursos naturais disponíveis no país. O artigo também apresenta um relato de um dos trabalhos de campo desenvolvidos, junto a uma empresa de consultoria ambiental, para um grupo concessor de energia elétrica por linhas de transmissão de alta tensão, trazendo as metodologias utilizadas e atividades realizadas, em uma das campanhas dos Programa de Educação Ambiental (PEA) desenvolvidos. This study aims to present how the environmental education is been used as a resource of great importance in the area of environmental consulting and assessment, aimed to mitigate environmental impacts generated by enterprises of power sector. Firstly, in this study, was made a contextualization about the environmental licensing process in Brazil, as well as the first environmental legislations responsible for regulating the use of natural resources available in the country. The article also presents a report of one of the fieldwork developed with an environmental consulting company for a group of electric power concession for high voltage transmission lines, bringing the methodologies used and performed activities, in one campaign of the Environmental Education Programs (EEP) developed.
