Carbon disulfide, CS2, is an important sulfur-containing species in the global environment. Its oxidation to SO2 and COS are basic atmospheric chemical processes in the sulfur cycle. The typical measurement methods for CS2 are gas chromatography with flame photometric detection (GC-FPD) and gas chromatography - mass spectrometry (GC-MS). This paper presents CS2 and SO2 long-term measurements made by the long path Differential Optical Absorption Spectroscopy (DOAS) technique in the winter of 2001 to 2002 in the urban area of Shanghai, China. We found a good correlation between SO2 and CS2 with average [SO2]/[CS2] ~ 2.1. Combined with an analysis of pollution sources near the measurement site, our measurements indicate that CS2 came mainly from a coal burning furnace close to the measurement site.
