Abstract

A passive sampler for collection of gaseous nitric acid (HNO₃) and nitrous acid (HNO₂) is based on a diffusion ofambient air through Teflon membrane and absorption of the pollutants on Nylasorb nylon filter. The sampler is simplein design, easy to make, inexpensive and resistant to harsh weather conditions. The sampler has been calibrated againsthoneycomb denuder systems in ambient southern California air and in controlled HNO₃ exposures. It is more precisethan the old open-face HNO₃ sampler. It can measure wide ranges of ambient HNO₂ and HNO₃ concentrations forextended periods of time and can be used for regional-scale monitoring of the pollutants.
