The research is focussed on identification of chemical and physical health hazards in the work environment, for risk assessment and prevention. We employ epidemiological methods in the search for causes of chronic diseases like cancer and cardiovascular disease. We use case-control studies, occupational cohorts as well as registry based population studies.
A central research topic is health effects of motor exhaust and particles. We have shown that exposure to motor exhaust causes lung cancer already at levels well below the Swedish occupational exposure limit, and an increased risk of myocardial infarction from exposure to combustion products. Ongoing studies investigate the effects of particles from various sources, like organic and inorganic particles, small vs. large particles, combustion vs. non- combustion particles etc. One group of studies deal with the increased risk of cancer and myocardial infarction in various occupational groups like chimney sweeps and professional drivers. A series of register-based studies deal with causes to specific diseases like Multiple sclerosis, Alzheimers disease, malignancies of the blood, skin, endocrine organs and breast, etc.
The quality of the information on exposure to occupational agents is methodologically very important. We aim to improve the methods for assessment of chemical and physical agents by developing and using job-exposure matrices, so called expert assessment, and combinations of these. Using effective epidemiological methods in linking exposure to diseases is a high priority. We also perform field studies of exposure conditions in various occupational groups, regarding the exposure to particles, motor exhaust, and combustion products.
