Effect of extremely low frequency electromagnetic field exposure on sleep quality in high voltage substations
This study aims to investigate the effect of extremely low frequency electromagnetic fields exposure on sleep quality in high voltage substations (132, 230 and 400 KV) in Kerman city and the suburbs. For this purpose, the electric field intensity and magnetic flux density were measured in different parts of substations, and then the occupational exposure was estimated by averaging electric fiel...
متن کاملP-105: Prenatal Effects Exposure to Extremely Low Frequency- Electromagnetic Field (ELF-EMF) on Pathology of Testis in Newborn Rats
Background: Human beings are unavoidably exposed to ambient electromagnetic fields (EMF) generated from various electrical devices and from power transmission lines. The effects of extremely low-frequency electromagnetic fields (ELF-EMF) on the biological functions of living organisms represent an emerging area of interest for human health. One of the critical issues is that EMF may adversely a...
متن کاملEffect of occupational exposure to extremely low frequency electromagnetic fields on level of thyroid hormones effective on fatigue
Background: The aim of this study was to assess exposure to extremely low frequency electromagnetic fields (ELF-EMFs) and its effects on secretion of thyroid hormones associated with symptoms of fatigue on electric arc welding workers. Methods: This study was carried out on two groups including 35 welders (as exposed) and 35 non-welders (as control). Extremely low frequency electromagnetic fie...
متن کاملEffect of Extremely Low Frequency Electromagnetic Field and/or GABAB Receptors on Foot Shock-induced Aggression in Rats
Introduction: The present study investigated the interactive effect of GABAB receptors and extremely low frequency electromagnetic field (ELF-EMF) on foot shock-induced aggression in rats. Methods: fifty adult male rats were randomly assigned into 10 groups. Groups 2, 4, 6, 8 and 10 were exposed to 50 Hz, 500 µT ELF-EMF for 30 days 8h per day while the remaining groups (1, 3, 5, 7 and 9) were...
