Indoor Combustion and Asthma
Section snippets
Woodstoves
Wood smoke includes a vast array of constituents forming a complex mix of particles of varying chemical and physical composition, making it difficult to identify any individual harmful constituent [4]. Thus, some have argued that it is best to examine the entire mixture rather than its individual constituents [4]. Factors such as frequency of use, whether the woodburning stove is a primary or secondary heater, ventilation, age, type and condition of the device, and size of home influence
Gas cooking stoves
Gas cooking stoves are an important source of indoor NO2. However, gas stoves tend to be used for shorter periods of time and are limited to the kitchen, resulting in a strong spatial gradient within the home. A large number of studies have investigated the relationship between gas cooking stoves and asthma prevalence or asthma symptoms. Both adults and children have been studied. Results are inconsistent, but exposure of children appears to be more consistent with risk than exposure of adults.
Discussion
This article did not find any studies that addressed the question of an association between indoor combustion and asthma incidence. To examine this question would require a cohort followed from birth. However, several studies considered increased asthma prevalence in association with combustion sources. Eight studies reported positive associations for asthma prevalence among children [9], [11], [12], [14], [15], [16], [25], [29]; two studies reported negative findings [22], [23]. Among adults,

2022, American Journal of Emergency MedicineCitation Excerpt :Third, charcoal burning releases many gases, such as carbon dioxide, CO, sulfur dioxide (SO2), and other harmless gases. However, gas-emitting heaters mainly emit carbon dioxide and CO, while other harmful gases are emitted at much lower levels than charcoal burning [19,28]. Some studies have found that SO2 exposure could accelerate hypoxia and induce brain impairment [14,29].
Exposure to biomass fuel is associated with high blood pressure and fasting blood glucose impairment in females in southern rural China
2021, Environmental ResearchCitation Excerpt :There were some interpretations for these discrepancies. The HAP resulting from cooking and heating is a known risk factor for the adverse health effects in developing countries, but less of a problem in developed countries (Belanger and Triche, 2008; Zheng et al., 2020). The frequency of usage, the type of biomass fuel, the ventilating conditions and the population density might have accounted for the different magnitude of adverse effects (Papakonstantinou et al., 2015).

2019, International Journal of Transportation Science and TechnologyCitation Excerpt :In recent years, the number of epidemiological studies investigating various environmental exposures that can modify the risk of asthma has grown substantially. These exposures include, but are not limited to, exposure to domestic pets (Almqvist et al., 2003; Apelberg et al., 2001; Carlsten et al., 2010; Dong et al., 2009), exposure to allergens, including animal, mouse, rat, cockroach, house dust mite, fungal, tree and weed antigens (Arshad, 2010; Arshad et al., 2002; Barnes et al., 2001; Breysse et al., 2010; Byrd and Joad, 2006; Carrer et al., 2001; Chen et al., 2011), exposure to parental and especially maternal tobacco smoke (Gilmour et al., 2006; Gilliland et al., 2001; Arruda et al., 2005; Chen et al., 2011; Chhabra et al., 1999), and exposure to indoor and outdoor air pollution (Belanger and Triche, 2008; Breysse et al., 2010; Khreis et al., 2017). From this list, we focus on exposure to outdoor air pollution.
