Forty-seven subjects exposed to formaldehyde (mean air concentration 0.45 mg/m3) and 20 unexposed subjects, all of whom were employed at a carpentry shop, were studied with regard to symptoms and pulmonary function. Symptoms involving eyes and throat as well as chest oppression were significantly more common in the exposed subjects than in the unexposed(More)
The combination of environmental chamber exposure and bronchoalveolar lavage (BAL) was used to study the effects of the common air pollutant nitrogen dioxide (NO2). Eighteen healthy nonsmokers were exposed to NO2 during 20 min in an exposure chamber during light bicycle ergometer work. All subjects were examined with BAL at least 3 wks before exposure, as a(More)
In a two-step study an exposure control method for occupational handling of permethrin was developed. Air sampling on a filter can be used in cases of exposure to permethrin in powder form. The detection limit is 0.001 mg/m3. If biological sampling is used, the acid metabolite moiety in the urine must be monitored. However, the uptake after exposure to(More)
Complaints of irritation in the eyes, nose and throat as well as dyspnea during work prompted this study to determine whether chain-saw exhaust produces acute exposure effects in loggers. Interviews concerning respiratory symptoms and rating of complaints were conducted for 211 loggers at industrial health care centers. Measurements of carboxyhemoglobin,(More)
AIMS Hypersensitivity to electricity (HE) is a common form of reported environmental illness in Sweden. Functional somatic symptoms has been attributed to exposure to activated electrical equipment, but no causal relationship to electromagnetic fields has been proved. In many cases, traumatic life events and psychosocial stress can be identified, but(More)
The combination of environmental chamber exposure and bronchoalveolar lavage (BAL) was used to study the time-course of the cell response in the human lung to nitrogen dioxide (NO2). Healthy subjects were exposed for 20 min to 7 mg NO2.m-3 (4 ppm), a concentration which occurs indoors in industries and is below the peak exposure limit for work places in(More)
Individuals who paint cars often complain to doctors about respiratory problems. Car painters are exposed to isocyanates, especially hexamethylendiisocyanate (HDI), and biuret modified HDI (HDI-BT). The mean exposure to HDI-BT was 115 micrograms/m3 in the air (range 10-385 micrograms/m3), which exceeds the time-weighted Swedish threshold level of 90(More)
BACKGROUND Predatory mites are used as biological pesticides worldwide for control of spider mites and other pests in greenhouses. The aim of this study was to evaluate the impact of occupational exposure to Phytoseiulus persimilis and Hypoaspis miles on IgE sensitization among a large group of Swedish greenhouse workers and to examine the relationship(More)
Because of reports of respiratory complaints in Swedish industrial arts (IA) teachers, a cross-sectional study was performed on 130 IA teachers in Stockholm to study the relationship between the work environment and health, and especially the aforementioned complaints. One hundred and twelve other school employees served as control subjects. Sex, age, and(More)
