Summary

A 5-day cohort diurnal FeNO study of exposed and unexposed to airway irritants during hair treatments and commuting.

Detailed description

The project aims to increase the knowledge of daily variations in FeNO with emphasis on exposure of airway irritants during hairdressing treatments in an occupational setting and commuting. Daily measurements of FeNO before and after workplace exposure in an exposed and an unexposed cohort during a workweek (Monday to Saturday) will indicate patterns of proinflammatory responses in a dose-dependent manner. These may or may not be indicative of an increased risk for airway related disease. Results may be used for further studies of occupational hygiene, airway related disease and identification of endogenous volatile organic compounds during proinflammatory responses.
