“…Laboratory chamber studies of kerosene heater emissions began in the early 1980s (Leaderer 1982; Traynor et al 1983; Yamanaka 1984). Emission factors for fine particulate matter (PM), CO, SO 2 , and NO x (NO 2 and NO), were estimated using a well-mixed-room mass balance model (single-box model).…”

“…Numerous studies demonstrated that heater design (radiant or convective) is influential on emissions of pollutants (Apte et al 1989; Cheng et al 2001; Leaderer 1982; Lionel et al 1986; Traynor et al 1983; 1987; 1990; Yamanaka et al 1979; Yamanaka 1984; Zhou et al 2000). EF co were, on average, four- to fivefold higher for radiant heaters than for convective heaters; conversely, EF NOx from convective heaters were two- to fourfold higher than from radiant heaters (Table 1), indicative of the hotter combustion temperatures of convective heaters.…”

Kerosene has been an important household fuel since the mid-19th century. In developed countries its use has greatly declined because of electrification. However, in developing countries, kerosene use for cooking and lighting remains widespread. This review focuses on household kerosene uses, mainly in developing countries, their associated emissions, and their hazards. Kerosene is often advocated as a cleaner alternative to solid fuels, biomass and coal, for cooking, and kerosene lamps are frequently used when electricity is unavailable. Globally, an estimated 500 million households still use fuels, particularly kerosene, for lighting. However, there are few studies, study designs and quality are varied, and results are inconsistent. Well-documented kerosene hazards are poisonings, fires, and explosions. Less investigated are exposures to and risks from kerosene’s combustion products. Some kerosene-using devices emit substantial amounts of fine particulates, carbon monoxide (CO), nitric oxides (NOx), and sulfur dioxide (SO2). Studies of kerosene used for cooking or lighting provide some evidence that emissions may impair lung function and increase infectious illness (including tuberculosis), asthma, and cancer risks. However, there are few study designs, quality is varied, and results are inconsistent. Considering the widespread use in the developing world of kerosene, the scarcity of adequate epidemiologic investigations, the potential for harm, and the implications for national energy policies, researchers are strongly encouraged to consider collecting data on household kerosene uses in studies of health in developing countries. Given the potential risks of kerosene, policymakers may consider alternatives to kerosene subsidies, such as shifting support to cleaner technologies for lighting and cooking.

“…SO 2 EF is taken from fuel #2. The air exchange rate has been taken at 0.5/h, the deposition rates on the surfaces are 1/h for NO 2 (Yamanaka, 1984), 2/h for SO 2 (Walsh et al., 1977), and negligible for the other pollutants. The resulting increases in the concentrations are given in Table 7.…”

Emission factors of gaseous pollutants from recent kerosene space heaters and fuels available in France in 2010

Our results show that in spite of new technologies and emission standards for unvented kerosene space heaters, as well as for the fuels, the use of these heaters in indoor environments still leads to NO(x) levels in excess of current health recommendations. Whereas injection heaters generate more nitrogen oxides than wick heaters, prolonged use of the latter leads to a soot buildup, concomitant with high CO emissions, which could be responsible for acute and chronic intoxications. The use of a biofuel in a wick heater is also of concern. Maintenance of the heaters and adequate ventilation of the room during use of kerosene space heaters are therefore of prime importance to reduce personal exposure.
