Observation of Carbon Disulfide by Differential Optical Absorption Spectroscopy in Shanghai
Artikel i vetenskaplig tidskrift, 2004

Carbon disulfide, CS 2 , is an important sulfur-containing species in the global environment. Its oxidation to SO 2 and COS are basic atmospheric chemical processes in the sulfur cycle. The typical measurement methods for CS 2 are gas chromatography with flame photometric detection (GC-FPD) and gas chromatography - mass spectrometry (GC-MS). This paper presents CS 2 and SO 2 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 SO 2 and CS 2 with average [SO 2 ]/[CS 2 ] ≈ 2.1. Combined with an analysis of pollution sources near the measurement site, our measurements indicate that CS 2 came mainly from a coal burning furnace close to the measurement site.
