Air pollutant emissions from kerosene space heaters
Science (New York, N.Y.)
|December 10, 1982
Summary
Portable kerosene space heaters emit harmful air pollutants like nitrogen oxides and carbon monoxide. Their use in homes can lead to indoor air quality exceeding health standards.
Area of Science:
- Environmental Science
- Indoor Air Quality
- Combustion Chemistry
Background:
- Portable kerosene space heaters are common heating devices.
- Concerns exist regarding the indoor air quality impact of combustion appliances.
- Understanding emissions from these heaters is crucial for public health.
Purpose of the Study:
- To quantify air pollutant emissions from portable kerosene space heaters.
- To assess potential health risks associated with their use in residential settings.
- To compare emission levels against established air quality standards.
Main Methods:
- Emissions were measured in a controlled environmental chamber.
- Emission factors for key pollutants were determined.
- Pollutant levels were analyzed for nitrogen oxides, sulfur dioxide, carbon monoxide, carbon dioxide, and oxygen depletion.
Main Results:
- Emission factors for nitrogen oxides, sulfur dioxide, carbon monoxide, and carbon dioxide were established.
- Significant oxygen depletion was observed.
- Calculated exposures exceeded ambient air quality standards and, in some cases, occupational health standards.
Conclusions:
- Portable kerosene space heaters release pollutants that can degrade indoor air quality.
- Residential use may pose health risks due to exceeding air quality benchmarks.
- Further evaluation of ventilation strategies and heater design may be warranted.

02:37Standard Enthalpy of Formation
Enthalpy changes are typically tabulated for reactions in which both the reactants and products are at the same conditions. A standard state is a commonly accepted set of conditions used as a reference point for the determination of properties under other different conditions. For chemists, the IUPAC standard state refers to materials under a pressure of 1 bar and solutions at 1 M and does not specify a temperature. Many thermochemical tables list values with a standard state of 1 atm. Because...
02:12Enthalpy and Heat of Reaction
Combustion, commonly known as burning, is a reaction in which a substance reacts with an oxidizing agent, which in most cases is molecular oxygen, to liberate energy in the form of heat, light, or sound. The heat of combustion is also known as the enthalpy of combustion. The energy released when one mole of a substance undergoes complete combustion at constant pressure is called molar heat of combustion. Combustion reactions are exothermic; that is, they release energy, and their ΔH sign...
02:14Combustion Energy: A Measure of Stability in Alkanes and Cycloalkanes
The low reactivity in alkanes can be attributed to the non-polar nature of C–C and C–H σ bonds. Alkanes, therefore, were initially termed as “paraffins,” derived from the Latin words: parum, meaning “too little,” and affinis, meaning “affinity.”
Alkanes undergo combustion in the presence of excess oxygen and high-temperature conditions to give carbon dioxide and water. A combustion reaction is the energy source in natural gas, liquified petroleum gas (LPG), fuel oil, gasoline, diesel fuel, and...

02:23Autoxidation of Ethers to Peroxides and Hydroperoxides
Ethers represent a class of chemical compounds that become more dangerous with prolonged storage because they tend to form explosive peroxides when standing in the air. Autoxidation is the spontaneous oxidation of a compound in air. In the presence of oxygen, ethers slowly oxidize to form hydroperoxides and dialkyl peroxides.
01:25Aromatic Compounds: Overview
In general, the term ‘aromatic’ indicates a pleasant smell or fragrance from fresh flowers, freshly prepared coffee, etc. In the early history of organic chemistry, many benzene derivatives were isolated from the pleasant odor oils of the plants. For example, vanillin was isolated from the oil of vanilla, methyl salicylate from the oil of wintergreen, and cinnamaldehyde from the oil of cinnamon. They all had a pleasant odor; hence the name aromatic was given.

01:02Flame Photometry: Overview
Flame photometry, also known as flame emission spectrometry, is a technique used for the qualitative and quantitative analysis of elements present in a sample using a flame as the source of excitation energy. The concept of flame photometry was realized in the early 1860s by Kirchhoff and Bunsen, who discovered that specific elements emit characteristic radiation when excited in flames. The first instrument developed for this purpose was used to measure sodium (Na) in plant ash using a Bunsen...
