Magnetic fields of high voltage power lines and risk of cancer in Finnish adults: Nationwide cohort study
In this nationwide cohort study, 383,700 Finnish adults were identified by record linkages of nationwide registers. They all lived at some time during 1970-89 within 500m of overhead power lines of 110-400kV in a 50Hz magnetic field, calculated to be greater than or equal to 0.01µT. The numbers of observed and expected cases of cancer, standardized incidence ratios, and incidence rate ratios adjusted for sex, age, calendar year, and social class were assessed. Altogether 8415 cases of cancer were observed. All incidence rate ratios for both sexes combined were non-significant and between 0.91 and 1.11. Significant excesses were observed for multiple myeloma in men and colon cancer in women. The role of extremely low frequency magnetic fields in the pathogenesis of these tumours remains uncertain and the previously suggested associations between magnetic fields and other selected tumours were not confirmed.

Leukemia following occupational exposure to 60-Hz electric and magnetic fields among Ontario electric utility workers
Report on a nested case-control study of 1,484 cancer cases and 2,179 matched controls from a cohort of 31,543 Ontario Hydro (electrical utility for the province of Ontario, Canada) male employees. Associations of cancer risk with electric field exposure were evaluated and compared with previously reported findings for magnetic fields. Pensioners and active workers were followed for 18 years and 15 years, respectively. Exposures to electric and magnetic fields and to potential occupational confounders (such as ionizing radiation and known carcinogens) were estimated through job exposure matrices. Odds ratios were elevated for haematopoietic malignancies (all leukaemias) with cumulative electric field exposure. For cumulative magnetic field exposure, there were similar elevations. Evaluation of the combined effect of electric and magnetic fields for leukaemia showed significant elevations of risk for high exposure to both, with a dose-response relation for increasing exposure to electric fields and an inconsistent effect for magnetic fields. There was some evidence of a nonsignificant association for brain cancer and benign brain tumours with magnetic fields. For lung cancer, the odds ratio for high exposure to electric and magnetic fields was 1.84 (95% CI 0.69-4.94).

Sex differences in work-related injury rates among electric utility workers
Injury trends were examined by type, severity and how they occurred among a cohort of 9,582 female and 26,898 male electric utility workers employed during 1980-1992. Unadjusted injury rates were higher throughout the period for male workers. However, after adjustment for occupation, job experience and age, elevated rate ratios indicate that female workers have higher injury rates. The rate ratios were slightly higher for more severe injuries. Differences between male and female workers in training, physical capacity, task assignments, as well as other factors, could explain the observed injury trends.

Classification of fatal occupational electrocutions
The study describes fatal occupational electrocutions that occurred in Quebec, Canada between 1981 and 1988 and proposes a classification suitable for setting up a prevention agenda. Of 63 fatalities, an investigation report was available in 57 cases (90.5%). They all occurred among males, 70.2% of whom were under the age of 35; 49.1% were performing a task related to the construction sector. A principal factor analysis allowed classification of 90.2% of the fatalities in two categories: victims assigned to electrical tasks indoors and those assigned to non-electrical tasks outdoors. Victims in the first group (56.5% of the cases) were electrocuted by direct contact with current at voltages <10kV and those in the second by contact with current at voltages >10kV. The identification of the two patterns of electrocution provided an additional argument for shifting prevention strategies from worker education to reducing electrical hazards at their source.

Association between exposure to pulsed electromagnetic fields and cancer in electric utility workers in Quebec, Canada, and France
The authors report the association between exposure to pulsed electromagnetic fields (PEMFs) and cancer in electric utility workers in Quebec, Canada (follow-up, 1970-1988), and France (follow-up, 1978-1989), among whom 2,679 cases of cancer were identified. Exposures were assessed through a job-exposure matrix based on about 1,000 person-weeks of measurements from exposure meters worn by workers. Exposures were considerably higher in Quebec than in France. No association was found between PEMFs and cancers previously suspected of association with magnetic fields (leukaemia, other haematopoietic cancers, brain cancer or melanoma). However, there was a clear association between cumulative exposure to PEMFs and lung cancer, with odds ratios rising to 3.11 (95% confidence interval (CI) 1.60-6.04) in the highest exposure group (84 cases). The association was not explained by smoking or other occupational exposures.

Musculoskeletal symptoms among electricians
A questionnaire survey was carried out among 308 apprentice electricians to assess the prevalence of musculoskeletal symptoms. Low back pain was common among these workers and resulted in medical care, missed work or light duty for almost 35% of participants. Hand/wrist symptoms and neck discomfort were also common. These workers continued to work with symptoms that are classifiable as cumulative trauma disorders. A history of injury was correlated with the subsequent prevalence of musculoskeletal symptoms.

Electric and magnetic fields at three pulp and paper mills
Extremely low frequency (60Hz) electric and magnetic field levels were measured at three Canadian pulp and paper mills, using area point-in-time measurements. Most electric field levels were below limit of detection of 1V/m; the highest measured field was 47V/m. Measured magnetic field strengths ranged from less than the limit of detection of 0.125mG to 706mG, with a median of 1.6mG. Magnetic field levels were higher in mills that consume more electric power, but worker exposures could not be predicted according to plant power consumption. Overall, electric and magnetic field levels in the three pulp and paper mills were similar to those experienced by the general population. However, maximum magnetic field intensities in some areas were as high as those experienced by electrical workers.

Epidemiological surveillance of a group of workers exposed to very high energy electromagnetic fields in the French company Electricité de France
Surveillance épidémiologique d'un groupe professionnel d'Electricité de France: les travailleurs sous très haute tension [in French]
The certified sickness absence of 351 lines fitters working on live transmission lines running at 63kV or more was studied for the years 1989 and 1990 and compared with that of two groups: office workers not exposed to electromagnetic fields and a sample of EDF-GDF workers with comparable level of responsibility and age. The line fitters were numerous to leave their work for medical reasons but their absenteeism measured by the number of spells and the duration of absence per year was lower or equal to those of the two other groups. They seemed to have more accidents at work and fewer mental disorders. This study is the first stage of an epidemiological surveillance of occupational diseases of workers exposed to specific health hazards. It will be supplemented by a longitudinal study.

Review of occupational exposure to optical radiation and electric and magnetic fields with regard to the proposed CEC physical agents directive
Part 1 of this review considers occupational exposure to optical radiation, ultra-violet radiation, lasers and infrared radiation. It is concluded that if suitable control measures are enforced, there should be very few cases where optical radiation emissions from artificial sources exceed the ceiling levels in the proposed CEC Directive; areas where overexposure may occur are highlighted. Part 2 covers occupational exposure to electric and magnetic fields, static fields, extremely low frequency fields, broadcast and telecommunications, radar and navigation, heating, visual display units and other sources and identifies a number of areas where the action and hazardous activity levels proposed by CEC may be exceeded.

CIS 95-1846 NIOSH Alert - Request for assistance in preventing injuries and deaths from metal-reinforced hydraulic hoses
This data sheet describes hazards associated with the use of metal-reinforced hydraulic hoses on aerial bucket trucks near energized power lines. Such hoses may rupture and cause fires if they contact power lines; electric current flowing through the metal reinforcement may also create an electrocution hazard. The use of nonconducting hydraulic hoses near energized power lines is recommended.

Skin nerve stimulation caused by low frequency electric field
Radiated power from certain radio transmitters (1000kW) used in ship-to-shore communications generates strong electric fields which can cause unpleasant skin nerve stimulation in persons who touch nearby metallic objects. Such stimulation is caused by an electric current crossing the area of the skin in contact with the object. Results of a study on threshold current perception are presented. An important parameter in the characterization of nerve excitation for the range 1 to 100kHz is the charge flowing across the skin, membrane or other organs during one duty cycle. A table shows the magnitude of this charge and the effects for a range of current values.

Leukemia in telephone linemen
This case-control study examines potential associations between telephone linework and the occurrence of leukaemia with the exception of chronic lymphocytic leukaemia. Workers with lifetime exposure scores to extremely low frequency non-ionizing radiation above the median for the population show an excess of leukaemia 2.5 times higher than workers below the median (95% confidence interval (CI) 0.7-8.6). Those individuals with a long duration of employment in jobs with intermittent peak exposures may be at a higher risk of leukaemia than those with a constant exposure level. Analyses that allow for a latent period suggest that the risk is associated with exposures that occurred 10 or more years before death. Workers with peak exposure scores to extremely low frequency non-ionizing radiation above the median have odds ratios of 2.4 (95% CI 0.7-9.0) and 6.6 (95% CI 0.7-58) for latent periods of 10 and 15 years, respectively. The data suggest an increasing risk with increasing exposure (p for trend = 0.05) when cumulated scores are based on peak exposure scores. The numbers in this study are small and the differences observed may be due to chance.

Measurement of metallic particles extracted from the lung parenchyma of two electricians and one electrotechnician
X-ray spectroscopy and laser microprobe mass analysis were used to determine the chemical nature of particles extracted from the lung parenchyma of two electricians and one electrotechnician who had died of lung cancer. The retained particles were qualitatively representative of these workers' work history (e.g. the electrician who had worked in a mine had retained more silicates than the two others). The concentration of nickel in the lungs of these workers was higher than the concentrations measured in the lungs of 39 other workers who died of different types of cancers.

Magnetic field exposures in a petroleum refinery
Petroleum refinery workers were classified into groups based on the type of exposure sources and work conducted. Electricians were divided into three categories: high voltage electrical distribution (HVED) workers; low voltage electrical distribution (LVED) workers; and maintenance electricians (MNTE). A total of 48 individuals, 11 HVED electricians, 12 LVED electricians, 11 MNTE workers, and 14 controls were monitored for an 8-hour shift. Both the HVED and LVED groups were found to have average full-shift mean exposures slightly greater than 10 milligauss (mG). The MNTE group and the controls exhibited lower magnetic flux density exposures, with means between 2mG and 3mG. A special group of high voltage electricians were monitored during maintenance work on large current-limiting coils in the power distribution system. Individual full-shift magnetic field means ranged from 0.06 to 2.0 gauss (G), with an overall mean of 0.93G. Peak exposures ranged from 2.1 to 18G, with an average of 12.1G.
