“…Incomplete combustion and/or high‐temperature volatilization from fuels can be another source of carboxylic acids. For example, Kuo et al 301 determined an emissions factor for acetic acid from incense use to be 840 ± 520 µg per g of incense burned, based on experiments with four popular brands. Christian et al 302 measured emission factors of formic acid and acetic acid from biomass combustion.…”

Numerous acids and bases influence indoor air quality. The most abundant of these species are CO2 (acidic) and NH3 (basic), both emitted by building occupants. Other prominent inorganic acids are HNO3, HONO, SO2, H2SO4, HCl, and HOCl. Prominent organic acids include formic, acetic, and lactic; nicotine is a noteworthy organic base. Sources of N‐, S‐, and Cl‐containing acids can include ventilation from outdoors, indoor combustion, consumer product use, and chemical reactions. Organic acids are commonly more abundant indoors than outdoors, with indoor sources including occupants, wood, and cooking. Beyond NH3 and nicotine, other noteworthy bases include inorganic and organic amines. Acids and bases partition indoors among the gas‐phase, airborne particles, bulk water, and surfaces; relevant thermodynamic parameters governing the partitioning are the acid‐dissociation constant (Ka), Henry's law constant (KH), and the octanol‐air partition coefficient (Koa). Condensed‐phase water strongly influences the fate of indoor acids and bases and is also a medium for chemical interactions. Indoor surfaces can be large reservoirs of acids and bases. This extensive review of the state of knowledge establishes a foundation for future inquiry to better understand how acids and bases influence the suitability of indoor environments for occupants, cultural artifacts, and sensitive equipment.

“…[12][13][14] Incense burning is a common traditional practice in both temples and households across the Asia-Pacific region; in Taiwan, about half families burned incense at home. [15][16][17][18] However, the slow and incomplete combustion process produces multiple indoor air pollutants, [19][20][21][22][23] such as polycyclic aromatic hydrocarbon (PAH) and other components of particulate matter (PM), which have been linked with deleterious health outcomes. 15,17,[19][20][21]23 Moreover, incense burning exposure during late pregnancy was found to be associated with increased risk of maternal hypertensive disorder, 24 along with the possible adverse health effects of asthma and respiratory tract symptoms, 18 decreased head circumference and body weight, 16 and delayed gross motor milestone development among term singletons.…”

Background: Household incense burning is a common ritual behavior in the Asia-Pacific region but has been associated with inferior developmental outcomes in term infants. We aimed to examine these associations among preterm infants. Methods: Information from 1190 mother-infant pairs during 6-and 18-month follow-up to the Taiwan Birth Cohort Study was examined for associations between household incense burning exposure and infant neurodevelopmental milestone achievement using multivariable Cox proportional hazard model with propensity score weighting, along with stratified, sensitivity, and decomposition analysis.Results: Household incense burning exposure was associated with delayed gross motor milestone achievement among all preterm infants according to the Cox model and after propensity score weighting. Meanwhile, associations for delayed development were found in gross motor domain milestones among late preterm infants, while fine motor domain delay was found among other preterm infants. Furthermore, the associations between household incense burning status and gross motor milestone delays were attenuated by the interaction between higher education level and household incense burning exposure status.Conclusions: Household incense burning exposure was associated with delays, and the motor domains affected differed according to degree of prematurity.

“…On long-term exposure, the effects could be contact dermatitis or worse (Eggert and Hansen, 2004). Research on the physical and chemical properties of particles from incense burning is of growing interest (See et al, 2007;Wang et al, 2007;Kuo et al, 2016).…”

Incense burning in temples is a common and popular ritual in India and other Asian countries. This study aims at assessing the quantity and size segregated distribution of particulate matter in temples of Kanpur city, India. Active air sampling was performed in three temples using the Micro Orifice Uniform Deposit Impactor (MOUDI). PM 10 mass concentrations as high as 2184 µg m -3 were recorded inside the temples. Mass concentration values for all samples exceeded the Central Pollution Control Board (CPCB) National Ambient Air Quality Standard (NAAQS) of 100 µg m -3 . Particle counts were high, and more than 99% of the numbers of particles generated were PM 2.5 . Particle coagulation is an active mechanism leading to formation of polydispersed particles. Most abundant particles occur in the accumulation mode (dp < 1 µm). Ventilation conditions and amount of incense burned are major factors affecting particle size distribution. Exposure through inhalation, to critically high concentrations of fine particulate matter generated via incense smoke especially for worshippers who frequent the temple and temple workers, raises health concerns. The results clearly indicate that incense smoke is a major source of particulate matter in the temple microenvironment and their chemical characteristics need further examination.
