Preliminary Study on the Emission Rules of Sulfur Derivative Pollutants in Putrefactive Cyanobacteria
摘要
Abstract
[ Objective] The aim was to study the Characteristics of the Emission of Sulfur Derivative Pollutants in Cyanobacteria. [ Method] Based on water odor in drink water from Gonghu Bay in Lake Taihu, the sulfur derivatives pollutants were extracted by head space solid phase microextraction (HS-SPME) and the odor substance was identified by gas chromatography and mass spectrometry (GC-MS). Decomposed simulation was conducted in closed tube of water and cyanobacteria samples collected from Gonghu Bay in Lake Taihu. The cyanobacteria rotten odor substances was analyzed and detected by HS-SPME-GC-MS for 10 days. The sulfur derivative pollutant was expounded. [ Result] The primary or secondary metabolites by Cyanobacteria in water samples such as β-cyclocitral, indol, methylphenol, mercaptan and thioether were detected with scan. During the decomposition process, the emission of β-cyclocitral changed little. The maximum emission of dimethyl trisul-fide appeared on the seventh and eighth day. The maximum emission of dimethyl disulfide appeared on the forth day. The maximum emission of the dimethyl sulfide was on the eighth and ninth day. The maximum concentration of dimethyl Irisulfide was 2 344. 79 ng/L, which was much more than the olfactory threshold. [Conclusion] The sewage in Gonghu Bay in the end of May in 2007 resulted from the accumulation of cyanobacteria.关键词
