  1. Occupational Exposure of Finnish farmers Introduction: * Linko (1947) published a case of farmers’ lung * first study at the end of 1970', “farmers exposure to microbes” in Kuopio Regional Institute of Occupational Health * since the year 1980 several studies have been published concerning chemical, physical and biological agents in different types of environments in agriculture FIOH/Kyösti Louhelainen, Kuopio - twinning Tarto 6/2003

  2. Occupational Exposure of Finnish farmers Cocktail = Possible connections of exposures and diseases: Exposures Diseases Inhalable dust Molds Endotoxins Allergens Bacteria Welding fumes (Zn) Pesticides Cleaning/desincfection Working postures Lighting Noise Vibration Chronic bronchitis Farmer´s lung ODTS (grain fever) Asthma Rhinitis Metal fever Poisoning Skin symptoms Musculoskeletal symptoms Accidents Hearing loss Comfort FIOH/Kyösti Louhelainen, Kuopio - twinning Tarto 6/2003

  5. Occupational Exposure of Finnish farmers Why to measure occupational factors ? - occupational diseases are common among farmers in Finland so it is important to decrease he number - Number of accidents are numerous and also fatal injuries occur - Through research we can find solutions to control methods FIOH/Kyösti Louhelainen, Kuopio - twinning Tarto 6/2003

  6. Occupational Exposure of Finnish farmers Microbes, molds, bacteria Exposure at cow farms : * at 70’s and 80’s quite high * during 90’s decreasing and still going downward * Analysis: - mold specific cultivating petri dishes - total number with filter sampling and staining * result: knowledge (?) of hazardous species, means for mold control (hay dryers, chemical treatment of hay, grain, etc) Exposure at swine farms : * usually higher than cow farms FIOH/Kyösti Louhelainen, Kuopio - twinning Tarto 6/2003

  7. Occupational Exposure of Finnish farmers Total dust Inorganic during outdoor work * high concentrations during tilling, sowing, harvesting Organic dust indoors * cow farms; (next slide) * swines; usually higher than in cow farms * poultry; at the same level as in swine houses OEL: organic dust 5 mg/m3, inorganic 10 mg/m3 FIOH/Kyösti Louhelainen, Kuopio - twinning Tarto 6/2003

  8. Occupational Exposure of Finnish farmers Dust exposure at cow farms FIOH/Kyösti Louhelainen, Kuopio - twinning Tarto 6/2003

  9. Occupational Exposure of Finnish farmers Gases * mainly ammonia, carbon dioxide, hydrogen sulfide have been measured * most often cow farms have been measured results: cow; (next slide) swines: high NH3 concentrations, moderate CO2 poultry: floor units high NH3 concentrations, H2S; very rare gas in cow houses, seldom in deep bed swineries, but has cause fatalities during liquid manure handling OEL: Ammonia 20 ppm, Carbon Dioxide 5000 ppm, Hydrogen Sulfide 10 ppm FIOH/Kyösti Louhelainen, Kuopio - twinning Tarto 6/2003

  10. Occupational Exposure of Finnish farmers The mean concentrations of CO2 and NH3 in cow houses FIOH/Kyösti Louhelainen, Kuopio - twinning Tarto 6/2003

  11. Occupational Exposure of Finnish farmers Pesticides: - Average farmer´s exposure to pesticides is quite low in Finland * small amounts of pesticides are used, 1-2 days / summer * effective low-portion liquids * farmers are afraid of poisons - More exposure to potato, sugar beet, carrot farmers, tens of days in summer, typical types are herbicides, insecticides - Biomonitoring blood or urine: farmers are involved quite seldom - Testing of sprayers and the test of farmer every 5 years, every 10 years for extremely dangerous pesticides FIOH/Kyösti Louhelainen, Kuopio - twinning Tarto 6/2003

  12. Occupational Exposure of Finnish farmers Noise: 1980’ 1990’2003 med range med range med range cow 72 66-85 80 70-88 76 70-82 swine 88 77-92 poultry 81 77-88 OEL: 85 dB(A), animal buildings 65 dB FIOH/Kyösti Louhelainen, Kuopio - twinning Tarto 6/2003

  13. Occupational Exposure of Finnish farmers Noise levels in cow houses: Work Median (dB(A)) range (dB(A)) Milking 75 (72-77) Milking and pressure cleaning 80 (80-81) Feeding, drying 77 (73-79) Use of tractor or loader 85 (78-90) FIOH/Kyösti Louhelainen, Kuopio - twinning Tarto 6/2003

  14. Occupational Exposure of Finnish farmers Vibration : - Tractor and harvester work was analysed at the beginning of 1980 - harrowing the worst, harvesting not - Tractors were measured in harrowing work in 1993. Farmers exposure to vibration was high and the daily 8-hour "fatigue-decreased proficiency boundary" (ISO 2631/1) was exceeded in all tractors FIOH/Kyösti Louhelainen, Kuopio - twinning Tarto 6/2003

  15. Occupational Exposure of Finnish farmers Ventilation of buildings - Ventilation has an effect to gases, temperature, moisture - Indoor work during wintertime problematic to the animals, structures and farmers - ventilation is difficult to design , construction is easier but the farmers try to buy and build cheap solutions and then problems rise FIOH/Kyösti Louhelainen, Kuopio - twinning Tarto 6/2003

  16. Occupational Exposure of Finnish farmers Fatal Injuries FIOH/Kyösti Louhelainen, Kuopio - twinning Tarto 6/2003

  17. Occupational Exposure of Finnish farmers Fatal Injuries FIOH/Kyösti Louhelainen, Kuopio - twinning Tarto 6/2003

  18. Occupational Exposure of Finnish farmers Accidents FIOH/Kyösti Louhelainen, Kuopio - twinning Tarto 6/2003

  19. Occupational Exposure of Finnish farmers What all this means ? * The occupational exposure of Finnish farmers - is quite well documentated - had decreased a lot in some cases, in same not so much - could be much better, if control methods had been implemented more properly FIOH/Kyösti Louhelainen, Kuopio - twinning Tarto 6/2003
