Title Short term exposure to airborne microbial agents during farm work: Exposure-response relations with eye and respiratory symptoms
Bibliographic information Feb. 2001, Vol.58, No.2, p.113-118. 29 ref.

Abstract Airborne exposure to microbial agents of 106 Norwegian farmers and their spouses was measured while carrying out specific tasks. Fungal spores, bacteria, endotoxins, β(1-3)-glucans, fungal antigens specific for Penicillium and Aspergillus species, and mites were measured by methods not based on microbial cultures. Also silica, inorganic and organic dust, ammonia, hydrogen sulfide and nitrogen dioxide were measured. Respiratory, nose and eye symptoms experienced during measurements were recorded by a short questionnaire. Prevalences of work related symptoms were: wheezing 3%; chest tightness 7%; cough 14%; eye symptoms 18%; nose symptoms 22%. Prevalence ratios for nose and eye symptoms were 4-8 after exposure to 20-500x103 fungal spores/m3 and higher, and a prevalence ratio for cough was 4 after exposure to 500-17,000x103 fungal spores/m3. Nose symptoms were also associated with exposure to silica with prevalence ratios of 4-6 after exposure to 0.015-0.075mg/m3 and higher.
