LoginThe sink or removal rates for two reactive indoor air contaminants (NO2 and SO2) were evaluated in an environmental chamber as a function of material type (painted sheetrock, wallpaper and carpeting), variable surface area of the material, relative humidity and air mixing. Sink rates for SO2 are generally higher than those for NO2. The sink rates for NO2 and SO2 were found to increase with material surface roughness and material surface area. Increases in relative humidity had a pronounced positive impact on SO2 sink rates and a smaller but significant impact on NO2 sink rates. The degree of air mixing was found to have a pronounced impact on both SO2 and NO2 sink rates.
