Responses to odors in occupational environments

PURPOSE OF REVIEW: There is mounting evidence that the presence of airborne chemicals that produce odor and irritation can be a significant impediment to a productive and healthy workforce, even among individuals without chemical sensitivity. RECENT FINDINGS: Studies investigating odor and irritant-induced symptoms in occupational environments suggest that poor indoor air quality, coupled with psychosocial factors such as the work environment, personality and stress, can lead to the development of building-related complaints and exacerbate chemical intolerance and symptoms. The practice of introducing pleasant odors in the workplace to improve productivity and mood is not well supported by current research. SUMMARY: Managing the response to odors and irritants in the workplace is critical to maintaining the health and well being of workers. There is a critical need for regulatory organizations in the United States and elsewhere to harmonize guidelines for occupational exposure limits. In addition, management must engage in risk communication and education of workers in order to ensure that misperception of risk from odors does not lead to illness and loss of well being.
