• This paper attempts to assess health risks associated with nitrogen oxides (NO_x) exposures. Experimental animal studies show that continuous or intermittent exposures to concentration of 0.04 to 0.5ppm nitrogen dioxide (NO_2) produce a number of pulmonary and systemic effects. Controlled human exposure studies show that short-term exposures to 0.3 to 0.5ppm NO_2 or 1.0ppm nitric oxide produce bronchoconstriction and blood biochemical changes in some subjects. When we consider together both findings of the animal and human exposure studies, we may suggest with some reliability that the concentrations of NO_x in ambient and indoor air pollutions may have adverse health effects on some subjects, and may partly contribute to the respiratory symptoms or illness and reduced pulmonary function observed in the epidemiological studies.
