Abstract
Nitrogen dioxide (NO2) is one of air pollutants, and environmental standards are set for the outdoor conditions. In the outdoor environment, NO2 is mainly emitted from vehicles and factories, and in the indoor condition, the high concentrations of NO2 are generated from open-type oil stoves especially in winter. NO2 clearly has an adverse effect on human lungs; therefore it is important to reduce the indoor NO2 concentration in order to decrease the incidence of asthma, which can be said as a national disease. There are some reports related to indoor NO2 concentration measurements in several Japanese areas, which mainly used diffusive sampling device as a measurement method. Although the diffusive sampling device is easy for use without special technique, it needs 24-hours for sample collection and the analytical results could not obtained on site because ion-chromatograph instrument is needed for analysis. In this report, the analytical chip which employed the reaction between salzman's reagent and NO2 in the porous glass is described, and indoor NO2 measurement using the analytical chip is also mentioned.
