The authors report on the reaction of SO[sub 2] and NO[sub 2] in sub-ppm concentrations in humid air with a copper surface. The deposition of SO[sub 2] was studied in a time-resolved manner and the formation of HNO[sub 2] was measured. Corrosion products were analyzed using XRD, FTIR, FTIRAS, and ion chromatography. S[sup IV]-O species on the copper surface was analyzed quantitatively using a sensitivity of 10[sup [minus]11] mol. Corrosion rates and corrosion products are reported. The corrosion of copper in humid SO[sub 2]-polluted air is accelerated strongly by the presence of NO[sub 2].
