Abstract/OtherAbstract:
Recent research has demonstrated that nitrous acid (HONO) is produced in indoor environments by NO2 reacting with interior surfaces, and is also emitted directly by some combustion sources. We have recently characterized the interference by HONO to NO2 measurements made by several commonly used continuous NO2 monitors. This paper reports on the effect of HONO on NO2 measurements made by passive sampling devices. The objective of this study was to evaluate this interference, and the accuracy and precision of passive samplers used for indoor NO2 measurements. We report that HONO interferes quantitatively with three of the four NO2 passive samplers tested.
