Extremely low frequency magnetic fields and fertility: a follow up study of couples planning first pregnancies
Objectives—To evaluate the impact of extremely low frequency (ELF) magnetic fields on markers of human fertility. Methods—A follow up study of time to pregnancy, semen quality, and reproductive hormones was conducted among couples planning first pregnancies (36 males were welders and 21 were non-welders). The male and the female partner were monitored for exposure to ELF magnetic field by perso...
متن کاملJob Stress among Workers Exposed to Extremely Low Frequency Electric and Magnetic Fields in a Combined Cycle Power Plant
Introduction: Exposure to the low frequency electric and magnetic fields (ELF-EMF) is very common in workers occupied in the combined cycle power plant during work shifts The present study aimed to measure ELF-EMF flux density among shift and non-shift workers, determine job stress among workers and office workers, and identify major factors associated with job stress in the studied groups. M...

متن کاملExposure of school employees to extremely low frequency magnetic fields.
This study was initiated to determine and compare daily occupational exposure (OE) and non-occupational exposure (NOE) of three employee groups of teachers, maintenance workers and secretarial staff in a Canadian school district. The time-weighted average (TWA) individual OE for subjects ranged from 0.4-3.8 milligauss (mG), and the TWA NOE ranged from 0.2-7.1 mG. TWA OE and NOE were 1.2 mG and ...
متن کاملExtremely low-frequency electromagnetic fields disrupt magnetic alignment of ruminants.
Resting and grazing cattle and deer tend to align their body axes in the geomagnetic North-South direction. The mechanism(s) that underlie this behavior remain unknown. Here, we show that extremely low-frequency magnetic fields (ELFMFs) generated by high-voltage power lines disrupt alignment of the bodies of these animals with the geomagnetic field. Body orientation of cattle and roe deer was r...
