Decay Constant of Nitrogen Dioxide in Indoor Materials of Houses
Abstract
Indoor air quality can be affected by indoor sources, ventilation, outdoor levels, and removal. Variousindoor and outdoor combustion sources make nitrogen dioxide(NO2), which is a by-product of hightemperature fossil fuel combustion. Especially, the presence of gas ranges and smoking have been identifiedas two of the major factors contributing to indoor NO2 exposures. In this study, the relative efficiencies forNO2 removal by a large number of materials are presented. This work has demonstrated that reactions withindoor surfaces represents a significant sink for NO2, and that these reactions currently are effecting aconsiderable degree of control over indoor NO2 levels. It seems that this control could be enhanced byjudicious selection of furnishings and construction materials. Improved understanding of that rates andmechanisms of the removal process will permit optimization of the process for indoor air qualityimprovement.
