Biological effects of power frequency electric and magnetic fields. Background paper
Although there is no significant transfer of energy from power-frequency fields to biological systems, some animal cells and tissues respond to such fields in the laboratory. Whole-animal and human experiments have examined 5 categories of effect: on mood or behaviour; on physiological variables such as growth or respiration; on specific biochemicals such as hormones that regulate physiological and psychological functions; on biological rhythms; on the epidemiology of cancer, especially leukaemia and brain cancer. The results are complex and inconclusive, but the epidemiological evidence is beginning to provide a basis for concern about risks from chronic exposure. If power-frequency fields do pose a health risk, high-voltage transmission lines will not be the only source of concern: distribution lines, wall wiring, appliances and lighting fixtures also produce such fields, and are much more common than transmission lines.

Radiation by visual display units
Strahlende Schirme [en alemán]
Sweden has set a stringent limit on the level of electromagnetic radiation emitted by visual display units (VDUs). Electromagnetic radiation by personal computers on the German market can be up to 40 times the level allowed by Swedish standards. A table provides information on the protection offered by various types of filters used on VDUs. Proof now exists that VDUs emit (even if in extremely small quantities) flame retardants such as dibenzofurans, which are highly toxic and particularly dangerous during manufacturing of the VDUs or in case of fire. An efficient ventilation is recommended until more restrictive standards are issued in Germany.

Power frequency electric and magnetic fields - A personal exposure meter
Kraftfrekventa elektriska och magnetiska fält - En personburen mätutrustning [en sueco]
A personal exposure meter that samples and stores the strength of a 50Hz electric and magnetic field every 15 seconds was designed and evaluated. Readings of the electric field to which workers were exposed during different work tasks in a switchyard had a good correlation with the current that was induced in the human body. The deviation was usually less than 30%. The magnetic field could be analysed in 3 orthogonal directions with respect to the wearer's body or regardless of incidence direction. In the latter case the readings were shown to be, on the average, strongly correlated with the maximum component of the fields.

Symptoms and subjective discomforts in "hypersensitivity to electricity"
Symptom och subjektiva besvär vid "överkänslighet mot elektricitet" [en sueco]
Report on "hypersensitivity to electricity", based on anamneses for 32 patients. A diversity of symptoms and subjective discomforts were reported. 31 of the 32 subjects (97%) indicated diffuse skin disorders such as patchiness, rosacea, heat, prickly sensations, stiffness, itching etc. 20 persons (63%) presented symptoms of the nervous system, such as giddiness, tiredness and lack of energy, headache, difficulty remembering things etc. 17 persons (53%) also reported eye symptoms and disturbances of vision. The pathological symptoms were often pronounced and in 25% of the cases they resulted in sick leave. Symptoms affecting the nervous system were more persistent than were dermatological symptoms. 29 subjects (91%) referred to the display screen as the triggering factor, but other factors were also referred to: fluorescent light tubes, sunlight, electrical appliances, ventilation devices etc. Discontinuation of VDU work was the most effective countermeasure, especially for dermatological symptoms.

Occupational asthma due to a repair process for polyethylene-coated electrical cables
The case of an electrical cable repairer is reported who presented with symptoms suggestive of occupational asthma. A supervised workplace challenge test confirmed this diagnosis and laboratory challenge studies implicated heated polyethylene repair tape containing the chemical cross-linking agent dicumyl peroxide as the cause. Similar cross-linking processes are widely used in the cable manufacturing industry and the possibility of occupational asthma occurring in other settings may need to be considered.

Acute effects of ELF electromagnetic fields: A field study of linesmen working with 400kV power lines
The aim of the study was to investigate the possible acute effects of exposure to electric and magnetic fields. 26 experienced linesmen were studied during 2 working days while performing simulated routine inspections of insulators on steel poles of a 400kV power line, alternately live and dead. Exposure to electric and magnetic fields was measured using personal monitoring instruments. The mean exposure for the working day was estimated to be 2.8kV/m (SD=0.35) and 23.3µT (SD=4.2). The possible effects of exposure were studied using a battery of 4 automated performance tests, EEG, a mood scale, and a questionnaire to assess subjective symptoms. Furthermore, blood samples were collected for each subject on 3 different occasions during each workday, in order to test for possible hormonal changes. No statistically significant differences were found that could be attributed to possible exposure to electromagnetic fields.

Generation of triboelectric charge in textile fibre mixture and their use as air filters
A study was made of the sign, magnitude and lifetime of the electric charge developed by the triboelectric exchange between textile fibres of different chemical type. The development of the charge is shown to take place to such an extent as to be useful in the production of efficient air filters. Such filters are stable if one of the components of the mixture is of a highly insulating type. Material made in this way is shown to have a high filtration efficiency and is capable of satisfying existing standards with ease.

Chronic effect of variable electric fields on the endocrine system of mice
Hroničeskoe dejstvie peremennogo ėlektričeskogo polja na ėndokrinnuju sistemu belyh myšej [en ruso]
The age dependence of the reaction of the endocrine system to variable electric fields (VEF) on long-term (up to 320 days) exposure and the character of readaptation to VEF were investigated by determining the frequency of cytological abnormalities in the thyroid and adrenal glands of white mice up to 335 days after birth. VEF (50Hz, 40kV/m) were biologically active on both 10 day and longer exposure. Long-term exposure to VEF caused a cumulative increase of thyroid gland activity. This increase in activity resulted in an increase of energy expenditure and consequently in an acceleration of body aging. The extent and direction of the reaction depend on the age of animals.

Health hazards in work relating to the production and distribution of electricity - Interim report 4. Employees' assessment of their working environment
Hälsorisker i arbete vid elproduktion och eldistribution - Delrapport 4. De anställdas bedömning av sin arbetsmiljö [en sueco]
Interim report from a study on the health hazards in the electric power production and distribution industry in Sweden (the Elmiljö study). The report describes how 681 workers evaluated their working conditions six months after starting work. This evaluation was then compared to the evaluation made by a group of safety engineers. Noise, electric and magnetic fields, heavy lifting and unfavourable work postures were considered to be the most common exposure factors. Generally the work environment of the linemen and the power plant personnel were considered to be more severe than the work environment of the other occupational categories.

26 experienced linemen were studied for two days while they performed simulated, routine inspection of insulators on steel poles carrying a 400kV power line. The first day the inspection was performed on a power line in service. Mean exposure was estimated to be 28kV/m and 23.3µT respectively. The second day the same work was performed on an identical power line which was not in service. The possible effects of exposure were studied using automated behavioral performance tests, EEG, a mood scale and a questionnaire for the assessment of subjective symptoms. Blood samples were also collected for each subject. The analysis did not, however, reveal any signiicant difference between the two conditions which could be attributed to exposure to electromagnetic fields.

Exposure to extremely low frequency (ELF) electromagnetic fields in occupations with elevated leukemia rates
In this study, spot measurements were taken of ELF (< 100Hz) electric and magnetic field exposures of electrical workers at 114 worksites in various industries. For comparison, field strength was measured in 18 residences and 3 offices. The survey indicated that workers were in general more exposed to strong fields than were people in residential and office settings.

Ergonomics evaluation of modified industrial helmets for use in tropical environments
Some selected safety helmets manufactured in industrialised countries (IC) were modified to provide extra head ventilation and to reduce weight, in order to make them more acceptable to users in hot environments in developing countries (DC). The modified helmets were subjected to ergonomic evaluation in the laboratory and in the field. White helmets had some advantages in comfort (reduction of hotness) compared to other colours (red, green, etc.) when worn in the presence of radiant heat in the laboratory. Ventilation holes provided at the top of the shell seemed to reduce the greenhouse effect within the helmet shell which therefore felt less uncomfortable than a fully covered helmet. Even with a small reduction in weight, such as 45g in helmets weighing about 350g, the difference in weight was perceived by the wearers. In adapting helmets made in IC for use in tropical climates, head ventilation and low weight perception are important aspects in comfort which need to be considered. In addition to low cost, a harness material suitable for sweat absorption is required. Adjustability and sizing to fit 90% of the user population also needs to be considered.
