Cacosmia in healthy workers.
Self-reported cacosmia (i.e. feeling ill from the odour of xenobiotic substances) was studied in 151 young, healthy workers, unexposed to unpleasant odours and working in food stores without air-conditioning. Almost half (46%) of the sample reported feeling ill from the smell of chemical materials. Chemical odour intolerance induced headache, itching eyes, irritated or congested nose, dry and/or sore throat, cough, dizziness, and itching or rash. Cacosmic subjects showed a slight prevalence of the female sex, and had significantly higher symptom scores, anxiety, and depression than non-cacosmic subjects. Cacosmia may be related to multiple chemical sensitivity, sick-building syndrome and psychopathology. Individual variability in odour tolerance may substantially bias epidemiological studies on indoor air quality and health.
