Toxic Organic Pollutants from Kerosene Space Heaters in Iran

Abstract

The aim of this study was to investigate qualitatively the emission of toxic organic pollutants from an unventilated conventional kerosene space heater commonly used in Iran. A brand new common convective kerosene space heater, the "Aladdin," was used for this study. The well-tuned convective heater was operated in a 2.6-m(3) test chamber and then the emission was tested for organic pollutants. The emission was collected on Teflon-impregnated glass-fiber filters and XAD-2 resin and then analyzed by gas chromatography-mass spectroscopy. It was found that in addition to the ordinary pollutant gases, the heater emits aliphatic hydrocarbons, alcohols, polyaromatic hydrocarbons and the related nitrated compounds, phthalates, naphthalenes, and some other toxic organic compounds. However, it was found that the heater did not emit fluoranthene, cyclohexane, benzoic acid, and higher-molecular-weight alkylbenzenes, which could have resulted from the combustion of some other types of kerosene.
