Aliphatic aldehydes were found during the combustion of materials. Tobacco smoke contains aldehydes. Fire fighters were exposed to aldehydes when they conducted firefighting. Aldehydes in ambient air come mainly from the incomplete combustion of hydrocarbons and from photochemical reaction. Most aldehydes in ambient air are formaldehyde and acetaldehyde. Formaldehyde, acetaldehyde, propionaldehyde, butyraldehyde, and benzaldehyde were found in the atmosphere in Los Angeles. Burning Chinese… Expand

Measurements indicate that incense burning significantly elevates the concentrations of a number of carbonyls, most notably formaldehyde and acrolein, in the surrounding environments. Expand
Gas Pollutant Emissions from Smoldering Incense Using FTIR
This study characterized the effects of smoldering incenses and combustion conditions on gaseous pollutant yields. Incense comes in three types: non-smoke (A), reduced-smoke (B) and traditional-smokeExpand
Incense smoke: clinical, structural and molecular effects on airway disease
In Asian countries where the Buddhism and Taoism are mainstream religions, incense burning is a daily practice and people should reduce the exposure time when they worship at the temple with heavy incense smokes, and ventilate their house when they burn incense at home. Expand
Hazard assessment of United Arab Emirates (UAE) incense smoke.
Hazard assessment of incense smoke exposure suggests that incense burning contributes to indoor air pollution and could be harmful to human health. Expand
Effect of Relative Humidity on Polycyclic Aromatic Hydrocarbon Emissions from Smoldering Incense
Incense was burned in a controlled environment, in order to understand the effect of relative humidity on polycyclic aromatic hydrocarbons (PAHs) emissions from smoldering incense. The concentrationsExpand
Characteristics of polycyclic aromatic hydrocarbons and total suspended particulate in indoor and outdoor atmosphere of a Taiwanese temple.
PAH levels inside the temple were much higher than those measured in the vicinity and inside residential houses; and were in fact close to levels measured at a local traffic intersection in Tainan, Taiwan, and those in a graphite-electrode producing plant during the graphitization process. Expand
Vaporous and particulate‐bound polycyclic aromatic hydrocarbons in Chinese incense smoke
In this study, we determined polycyclic aromatic hydrocarbons (PAHs) in incense smoke by high performance liquid Chromatograph equipped with a fluorescence detector. The total yield of PAHs was 94.07Expand
Characterisation of airborne particles and associated organic components produced from incense burning
The oxygenated organics identified in this study have significant human health implications, especially for susceptible populations, when considering the worldwide prevalence of incense burning and resulting high respiratory exposures. Expand
Emission characteristics of air pollutants from incense and candle burning in indoor atmospheres
The performed kinetic measurements highlight the temporal evolution of the exposure level and reveal the importance of ventilation and deposition to remove the particles in a few hours in indoor environments. Expand
Combined cytotoxicity of co-exposure to aldehyde mixtures on human bronchial epithelial BEAS-2B cells.
Aldehyde mixtures have higher toxicity than that expected for additivity based on single aldehydes even at environmentally relevant concentrations, and the combined cytotoxicity may be enhanced through oxidative stress and the related Nrf2 pathway. Expand


Carcinogens in Chinese Incense Smoke
Using thin-layer arid column chromatography, several polycyclic aromatic hydrocarbons, including 3,4-benzopyrene, have been detected by ultraviolet absorption spectra, leading to the search for carcinogenic constituents in condensates from burning Chinese incense. Expand
Health hazards of fire fighters: exposure assessment.
The results indicate that firefighters are frequently exposed to significant concentrations of hazardous materials including carbon monoxide, benzene, sulphur dioxide, hydrogen cyanide, aldehydes, hydrogen chloride, dichlorofluoromethane, and particulates. Expand
Formaldehyde in conventional homes in Taiwan
Abstract A survey was conducted in the humid environment of Taipei City during April and May of 1991, to investigate the indoor formaldehyde exposure and its health effects on 117 conventionalExpand

Sources and concentrations of aldehydes and ketones in indoor environments in the UK
Individual aldehydes and ketones can be separated, identified and quantitatively estimated by trapping the 2,4-dinitrophenylhydrazine (DNPH) derivatives and analysis by HPLC. Appropriate methods andExpand
Occupational and other non‐dietary risk factors for nasopharyngeal carcinoma in Guangzhou, China
Use of tobacco products showed a moderate association with NPC; a lifetime exposure of 30+ pack‐year equivalents conferred a 2‐fold increased risk. Expand
Field studies of aldehyde chemistry in the Paris area
Abstract Measurements of carbonyl compound concentrations at different sites in the Paris area have been carried out. Interpretation of the results made use of the following data: generalExpand
N-Nitroso compounds and childhood brain tumors: a case-control study.
It is proposed that brain tumors in these young people are related to in utero exposure to N-nitroso compounds and their precursors, the most potent nervous system carcinogens known in experimental animals. Expand
Childhood leukemia and parents' occupational and home exposures.
Analysis of the information from the 123 matched pairs showed an increased risk of leukemia for children whose fathers had occupational exposure after the birth of the child to chlorinated solvents, spray paint, dyes or pigments, and cutting oil, as well as other potential risk factors associated with leukemia.
