Road-traffic noise can induce stress, which may contribute to mental health disorders. Mental problems have not received much attention in research. People perceive differently, affect the extent contributes poor at individual level. This paper aims assess relationships between outdoor traffic and annoyance use of psychotropic medication. We conducted a survey medication among residents Helsinki Capital Region Finland. also assessed associations road-traffic with sleep disorders, anxiety...
The increasing use of mobile phones by children and teenagers has raised concerns about their safety. Addressing such is difficult, because no data are available on possible effects from long-term exposure to radiofrequency (RF) fields during the development nervous system. Possible morphological functional changes were evaluated in central system young male Wistar rats exposed 900 MHz phone signal for 2 h/day 5 days/week. After weeks at whole-body average specific energy absorption rates...
Abstract The influence of sinusoidal 45‐Hz magnetic fields on the brain functions 20 volunteers was investigated in a double‐blind study using spectral analysis EEG and measurements Omega potentials reaction time (RT). field strength 1,000 A/m (1.26 mT) duration exposure 1 h. Ten were exposed to continuous ten received an intermittent (1 s on/1 off). Each person one real sham exposure. One half got first treatment after at least 24 For rest, sequence inverse. EEG, omega RT performed before...
SummaryChick embryos were exposed to sinusoidally oscillating 50 Hz magnetic fields during their first 2 days of development. In the series experiments field strengths 0·1, 0·3, 1 and 10 A/m used. The percentage abnormal (%AE) was 16 per cent in sham-exposed control group. %AE increased at (29 cent) (32 cent), but not 0·1 (16 or 0·3 (14 cent). second 0·4, 0·6, 0·9 1·35 17 group, 0·4 A/m, 19 0·6 36 A/m. Only group significantly different from controls. results this study suggest that exposure...
Human SH-SY5Y neuroblastoma and mouse L929 fibroblast cells were exposed to 872 MHz radiofrequency (RF) radiation using continuous waves (CW) or a modulated signal similar that emitted by GSM mobile phones at specific absorption rate (SAR) of 5 W/kg in isothermal conditions. To investigate possible combined effects with other agents, menadione was used induce reactive oxygen species, tert-butylhydroperoxide (t-BOOH) lipid peroxidation. After 1 24 h exposure, reduced cellular glutathione...
ABSTRACT Although static magnetic fields (SMFs) have been reported to induce only minimal biological effects, it has proposed that they may alter the effects of other agents, such as ionizing radiation. We sham‐exposed or exposed human SH‐SY5Y neuroblastoma cells 0.5‐, 1.5‐, 2.5‐, 3.5‐mT SMFs for 24 h either before after irradiation at 0, 0.4 2.0 Gy. After exposures, cell cycle distribution (subG1 apoptosis), reactive oxygen species (ROS) levels, caspase‐3 activity, and clonogenic survival...
The possibility of an association early pregnancy loss (EPL) with residential exposure to ELF magnetic fields was investigated in a case-control study. Eighty-nine cases and 102 controls were obtained from the data earlier study aimed at investigating occurrence EPL group women attempting get pregnant. Magnetic-field characterized by measurements residences. Strong measured more often case than control In analysis based on front door, cutoff score 0.5 A/m (0.63 microT) resulted odds ratio...
Abstract We studied effects of alternating magnetic fields on the embryonic and fetal development rats. Mated females Han:Wistar‐strain were sham exposed or continuously to a 50‐Hz field 20,000 pulse‐per‐second (pps) sawtooth from day 0 20 pregnancy for 24 h/day until necropsied 20. The respective peak‐to‐peak intensities 35.6 μT (sinewave) 15.0 (sawtooth). Each treatment group contained 72 bred females. Control animals kept under same conditions without field. No adverse seen in dams. mean...
Background Extremely low frequency (ELF) magnetic fields (MF) are generated by power lines and various electric appliances. They have been classified as possibly carcinogenic the International Agency for Research on Cancer, but a mechanistic explanation effects is lacking. A previous study in our laboratory showed that pre-exposure to ELF MF altered cancer-relevant cellular responses (cell cycle arrest, apoptosis) menadione-induced DNA damage, it did not include endpoints measuring actual...
Electromagnetic interference (EMI) can pose a danger to workers with pacemakers and implantable cardioverter-defibrillators (ICDs). At some workplaces electromagnetic fields are high enough potentially inflict EMI. The purpose of this in vivo study was evaluate the susceptibility ICDs external fields. Eleven volunteers pacemaker 13 an ICD were exposed sine, pulse, ramp, square waveform magnetic frequencies 2–200 Hz using Helmholtz coil. field flux densities varied 300 µT. We also tested...
Extremely low-frequency (ELF) magnetic fields (MF) have been associated with adverse health effects in epidemiological studies. However, there is no known mechanism for biological of weak environmental MFs. Previous studies indicate MF on DNA integrity and reactive oxygen species, but such evidence limited to MFs higher (greater than or equal 100 µT) those generally found the environment. Effects 10 30 µT were studied SH-SY5Y C6 cells exposed 50-Hz 24 h. Based earlier findings, menadione...
The objective of this study was to determine whether daytime occupational exposure extremely low frequency magnetic fields (MFs) suppresses nocturnal melatonin production. Sixty female volunteers were recruited. Thirty‐nine worked in a garment factory, and 21 office workers served as reference group. Exposure assessment based on the type sewing machine used MF measurements around each machine. Eye‐level flux density classify operators higher (>1 μT) lower (0.3–1 categories. A third group...
