项目摘要

Double shot pylorizer - GO - MS analysis of gas compounds emitted from burning of tropical peat (Mudan) identified more than 80 compounds were identified as aliphatic and aromatic hydrocarbons, furfurals and organic acids : acetic acid, benzene, pyridine, toluene, furfral, methyl-xylene, stylene, 5-methyl-furfral, phenol, o-cresol, p-cresol, 2-methoxyphenol, catechol 2,3-dihydrobenzofurane, levoglucosan, hydrocarbons with 12 to 32 carbon numbers and so on. Aliphtic hydrocarbons showed longer retention time than aromatic hydrocarbons. Benzene is one of the cancer-causing subatances for worker. Levoglucosan is one of the characteristic substances that emitted from the combustion of the paper or cellulose sample. The hydrocarbons with 4 to 32 carbon numbers which have none (saturated), one (monoen) and two (dien) double bonding. The chromatograms showed the similar patterns among different soil samples. However, the different concentrations of phenol were obtained, with the highest value in the Mukah sample. The different amount of compounds emitted from the combustion of tropical peat soil samples were found, based on the temperature and oxygen gas concentrations.Particulate substances emitted from burning of tropical peat were separated by the filters (No. 5A, 5B, and 5C) attached with a particulate substance collector and analyzed.

对燃烧热带泥炭（牡丹）排放的气体化合物进行的双射pylorizer -GO-MS分析确定了80多种化合物，这些化合物被确定为脂肪族和芳香族烃、糠醛和有机酸：乙酸、苯、吡啶、甲苯、糠醛、甲基-二甲苯、苯乙烯、5-甲基-糠醛、苯酚、邻甲酚、对甲酚、2-甲氧基苯酚、邻苯二酚2，3-二氢苯并呋喃、左旋葡聚糖，脂肪烃的保留时间比芳烃长。苯是工人的致癌物质之一。左旋葡聚糖是纸张或纤维素样品燃烧时释放的特征性物质之一。碳原子数为4 ~ 32的烃类，不含（饱和）、含1个（单烯）和2个（双烯）双键。不同土壤样品的色谱图具有相似的模式。然而，获得了不同浓度的苯酚，在Mukah样品中具有最高值。根据温度和氧气浓度，发现热带泥炭土样品燃烧释放的化合物的量不同。热带泥炭燃烧释放的颗粒物质通过与颗粒物质收集器相连的过滤器（5A、5 B和5C号）分离并分析。
