This report contained papers presented at the Sixth Joint FIOH-NIOSH Scientific Symposium which was held in Espoo, Finland in August 1995. Issues such as new directions for research at NIOSH and occupational health in Europe were discussed in the introduction. Several topics related to occupational safety and health were covered. Papers dealing with noise exposure examined evidence for noise induced hearing loss, factors which explain individual variability in hearing levels, a new method for assessing noise exposure, signal reconstruction methods in the retrospective analysis of occupational exposure, the genetics of noise induced hearing loss, and the attenuation of hearing protectors against military impulses noise. Fiber research examined the induction of micronucleated and multinucleated cells by glass fibers in cultured mammalian cells, various studies on asbestos (1332214), and studies on glass fiber induced cell transformation. In the field of agriculture, studies were presented concerning occupational health services for farmers, self reported health of farmers, nasal lavage for exposure and health assessment, biological monitoring of exposures to pesticides and wood preservatives, and herbicide exposure monitoring. Allergy research examined enzyme allergies in Finland, indoor air and exposure to allergens, fungal contamination of a residence, bacteria and fungi associated with insulation, immune system responses to occupational insults, and allergies caused by acrylate compounds. Ergonomic research considered work related musculoskeletal disorders, the use of wrist monitors, grocery warehouse workers, prevention programs, the epidemiology of low back pain, assessing the function of the musculoskeletal system, task related problems in computerized office work, rescheduling shift systems at a steel rolling mill, and a dose response study of night sleep length and the ability to sustain wakefulness. Studies on surveillance and prevention considered occupational health and hazards surveillance in Finland and target levels as tools for prevention.
