| Research Abstract |
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.
