用高效毛细管气相色谱质谱联用法鉴定蚊香烟中的有机污染物

IDENTIFICATION OF ORGANIC POLLUTANTS IN THE COILED MOSQUITO INCENSE SMOKE BY HPCGC-MS

人们每天在室内的时间大约在18h左右,即使户外工作人员,也在12h以上。因此,室内空气质量对人体健康的影响就很值得重视。室内空气所含的有害成分,不仅来自室外,有相当部分也来自人在室内的生活和活动,如燃煤、使用石油气炉、人体排出的有害气体以及室内吸烟等。夏季广泛使用的蚊香也是一种导致室内空气严重污染的因素;尽管目前市售蚊香已不含那些难以降解的有机氯农药,如666,而是使用天然除虫菊酯或人工合成的拟除虫菊酯类杀虫剂,但在燃烧过程中,除能释放出驱除蚊蝇的有效成分外,还会因燃烧不完全而产生一系列的有害于人体健康的有机污染物。本文报导应用色谱-质谱-计算机联用法,分析鉴定蚊香烟雾中有机污染物的结果。

this paper describes analytical results of organic pollutants in the coiled mosquito incense smoke by HPCGC-MS. Forty-six organic chemicals including some nitrogen-,oxygen- and sulpher- containing compounds have been identified. The toxic effects of 18 of them on the animals have been given. The indoor air quality is surely reduced by the smoke,so the smoke is considered to be harmful to human health.
