Abstract The United Kingdom workplace exposure limits for nitric oxide (NO) and nitrogen dioxide (NO2) are currently under review. In the meantime, both NO and NO2 were subject to a CHAN (Chemical Hazard Awareness Notice) of 1ppm (8-hr time-weighted average, TWA), significantly lower than the previous occupational exposure standards. Exposure to these oxides of nitrogen commonly arises in the construction industry from diesel engine exhaust emissions and from the use of explosives. This project addresses the effectiveness of real-time monitors, particularly personal monitors, at these concentration levels, and the environmental fate of NO and NO2 in the construction environment, using laboratory and field experiments.
