摘　　要：通过系列监测活动考察并验证了Compound composer软件系统在水体有机污染物快速定性、半定量工作中的可靠性。对2 mg/L的19种有机氯农药的标准溶液可以实现完全分离与准确定性,半定量结果的相对误差在-94%~42%;进一步利用该软件系统筛查某湖泊4条支流,共筛查出有污染物11种,除常见的钛酸酯类外,还检出苯并噻唑、2-苯氧基乙醇、甲硫基苯并噻唑、碳氢化合物和苯并呋喃等;最后还将其用于实际的突发环境应急事故应急监测中,筛查出特征污染物2-甲氧基-6-甲基苯胺,为锁定责任企业和环境执法提供了依据。结果表明,Compound composer软件在缺乏标准溶液的情况下,可以实现有机污染物的快速定性及半定量,尤其在突发环境污染事件中有一定的应用价值。Gas chromatography poser software through several were quantitatively and semi coupled with mass spectrometry （ GC - MS） was investigated using compound corn- monitoring activities. The standard solutions of nineteen organochlorine pesticides quantitatively tested. The relative deviations of the semi - quantitative results for 2mg/L standard solutions ranged from -94% to 42%. The water samples from four rivers were determined using this software. Eleven organic compounds were found besides Pthalate esters （PAEs）, dibenzofuran, methyl almi- tate, - ethyl - 1 - hexanol, benzothinaol, ethanol, 2 - phenoxy -, and 2 - （methyhhio） - benzothiazol. The compound composer software was also successfully used in the environmental emergency monitoring. The pollutant 2 - methoxy - 6 - methylaniline was detected to provide evidence for environmental management. The compound composer software could realize the rapid and quantitative and semi - quantitative tests without the standard solu- tion. This presented an applicable value in the environmental emergency monitoring.
