SELECTED ORGANIC POLLUTANT EMISSIONS FROM UNVENTED KEROSENE SPACE HEATERS

An exploratory study was performed to assess the semivolatile and nonvolatile organic pollutant emissions rates from unvented kerosene space heaters. A well-tuned radiant heater and maltuned convective heater were tested for semivolatile and nonvolatile organic pollutant emissions. Each heater was operated in a 27-m{sup 3} chamber with a prescribed on/off pattern. Organic compounds were collected on Teflon-impregnated glass filters backed by XAD-2 resin and analyzed by gas chromatography/mass spectrometry. Pollutant source strengths were calculated by use of a mass balance equation. The results show that kerosene heaters can emit polycyclic aromatic hydrocarbons (PAHs); nitrated PAHs; alkylbenzenes, phthalates; hydronaphthalenes; aliphatic hydrocarbons, alcohols, and ketones; and other organic compounds, some of which are known mutagens.
