   Författare :Hans Orru; Bertil Forsberg; Eda Merisalu; Marko Kaasik; Per-Inge Grennfelt; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Particulate matter; traffic; health impact assessment; cardiopulmonary; Environmental medicine; Miljömedicin; Occupational and Environmental Medicine; arbets- och miljömedicin;

   Sammanfattning : Particulate matter (PM) is one of the most studied and problematic pollutants due to its toxicity and relati­vely high concentrations. This thesis aims to clarify the main sources and exposures of PM in Tallinn and Tartu, study the associations with health effects, and estimate the extent of those effects with health impact assessment (HIA).

3. 2. Biomarkers of fish consumption and risk of stroke or myocardial infarction

   Författare :Maria Wennberg; Jan-Håkan Jansson; Ingvar Bergdahl; Maria Albin; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; fish consumption; omega-3 fatty acids; eicosapentaenoic acid; docosahexaenoic acid; methylmercury; selenium; lead; cadmium; stroke; myocardial infarction; erythrocytes; food frequency questionnaire; Environmental medicine; Miljömedicin; Epidemiology; epidemiologi; hälso- och sjukvårdsforskning; health services research; medicin; Medicine; Environmental Science; miljövetenskap; näringslära; Nutrition;

   Sammanfattning : The effect of fish consumption on the risk of cardiovascular disease has been extensively studied. Omega-3 fatty acids present in fish, namely eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), have been found to have beneficial effects through several mechanisms. In addition, selenium, an antioxidant, may be protective. LÄS MER

4. 3. Serious occupational injuries by "accidents" : possible means of prevention and injury mitigation

   Författare :Torgny Jarl; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Occupational; accident; injury; prevention; personal safety equipment; emergency action; commercial vehicles;

   Sammanfattning : An analysis of the circumstances preceding severe occupational injuries as a consequence of impacts has shown that well-known risks are of great importance in 75 per cent of the cases. This indicates that the subjective cause "neglect" is common. The negligence is distributed to the same extent among employers as among employees. LÄS MER

5. 4. Vibration exposure of the glabrous skin of the human hand

   Författare :Ronnie Lundström; Ludwik Liszka; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Vibration; hand; skin; mechanical impedance; mechanoreceptors; tactile perception; high-frequency;

   Sammanfattning : An occupational exposure to hand-arm vibration can cause a complex of neurological, vascular and musculo-skeletal disturbances, known as the 'vibration syndrome'. However, the underlying pathophysiological mechanisms are not at all clear. LÄS MER

7. 5. EXPOSURE TO PERSISTENT ORGANOCHLORINE POLLUTANTS AND MALE SEMEN FUNCTION

   Författare :Anna Rignell-Hydbom; Avdelningen för arbets- och miljömedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Miljömedicin; Environmental health; epididymal and accessory sex gland function; Y:X sperm chromosome ratio; sperm chromation integrity; sperm concentration; sperm motility; persistent organochlorine poluutants;

   Sammanfattning : Persistent organochlorine pollutants (POPs), such as polychlorinated biphenyls (PCB) and the insecticide dichloro-diphenyl-dichloro-ethylene (DDT) have been released into the environment mainly since the second World War. POPs accumulate especially in highly ranked predators of the aquatic food chain. LÄS MER
