What You'll Learn
Carbon monoxide, nitrogen and sulfur oxides, and other gaseous pollutants
Incense burning is a common tradition in many Asian countries, where it is used for religious and aesthetic purposes. However, incense smoke contains particulate matter, gaseous products, and organic compounds that can be harmful to human health.
One of the gaseous pollutants produced by burning incense is carbon monoxide (CO). Carbon monoxide is a colorless, odorless, and tasteless gas that is formed during the incomplete combustion of organic substances, such as hydrocarbons, wood, and incense. It has a high affinity for haemoglobin, reducing the blood's capacity to transport oxygen. Low concentrations of carbon monoxide can cause headaches, dizziness, weakness, and nausea, while high concentrations can be fatal.
Another gaseous pollutant found in incense smoke is nitrogen dioxide (NO2), a reddish-brown gas that is soluble in water and acts as a strong oxidant. Nitrogen dioxide is formed through the oxidation of nitric oxide (NO), which is emitted during the combustion of fuels in stationary or transportation sources, such as furnaces, fireplaces, and gas stoves. Exposure to nitrogen dioxide can irritate the airways and aggravate respiratory diseases, such as asthma. It is also a precursor to acidic rain and plays a role in nitrogen loading in forests and ecosystems.
In addition to carbon monoxide and nitrogen dioxide, incense burning also releases sulfur dioxide (SO2). Exposure to sulfur dioxide can have adverse health effects, including reduced work capacity, aggravation of cardiovascular diseases, impacts on pulmonary function, respiratory illnesses, lung irritation, and alterations in the lung's defense system.
Other gaseous pollutants produced by burning incense include volatile organic compounds (VOCs), such as benzene, toluene, and xylenes, as well as aldehydes and polycyclic aromatic hydrocarbons (PAHs). These compounds can have negative effects on human health, including respiratory system dysfunction and an increased risk of cancer.
Overall, the combustion of incense releases a range of gaseous pollutants, including carbon monoxide, nitrogen and sulfur oxides, and volatile organic compounds, which can have significant impacts on human health and the environment.

Volatile organic compounds (VOCs)
Incense is a smoke-emitting substance that has been used for centuries in religious and spiritual ceremonies. It is also commonly used for aromatherapy and meditation. However, recent studies have revealed potential health risks associated with burning incense, specifically the inhalation of particulate matter and volatile organic compounds (VOCs).
VOCs are chemicals with low boiling points, which means they can easily evaporate at room temperature. The burning of incense releases VOCs, contributing to indoor air pollution and potentially causing adverse health effects. The concentration of VOCs released during incense burning can be influenced by various factors, such as the type of incense, duration of burning, and ventilation of the space.
Several studies have identified and quantified numerous VOCs emitted from burning incense. These include n-hexane, cyclohexane, n-heptane, n-octane, n-nonane, n-decane, n-undecane, styrene, xylene isomers, 1,2,4-trimethyl benzene, ethylbenzene, benzene, and toluene. The emission rates of these VOCs can vary depending on the specific type of incense and the burning conditions.
The health risks associated with exposure to VOCs from incense burning have been a growing concern. Some of the potential health hazards linked to VOC exposure include respiratory issues, allergic reactions, and increased cancer risk. For example, a study by Sturton et al. (1966) reported a high incidence of nasopharyngeal carcinoma in Hong Kong males who burned incense regularly. Additionally, the presence of benzene in incense smoke has been associated with an increased risk of cancer, as it can act as a carcinogen when inhaled.
To minimize the potential health risks associated with VOC exposure from incense burning, it is recommended to choose natural incense products that are free from chemicals and artificial fragrances. Consumers should opt for incense made with pure, organic, or plant-based ingredients, ensuring a safer and healthier experience while still enjoying the benefits of this ancient practice.

Particulate matter
Incense burning releases particulate matter, which is a serious problem due to its effects on human health and the environment, particularly air quality. Particulate matter from incense burning is a significant contributor to air pollution, with levels in temples found to be over 100 times higher than the WHO-recommended limit.
The emission rates of particulate matter from incense burning are influenced by various factors, including the type of incense, the number of incense sticks burned simultaneously, and ventilation conditions. Different types of incense sticks can produce varying amounts of particulate matter, and low-quality incense has been associated with higher emission rates. The number of incense sticks burned simultaneously also impacts particulate matter concentrations, with higher amounts of incense resulting in increased PM levels. Additionally, poor ventilation can contribute to higher particulate matter concentrations in indoor environments.
The particulate matter emitted from incense burning contains pollutants such as volatile organic compounds (VOCs), carbon monoxide, and heavy metals. These pollutants can have adverse effects on human health, including respiratory issues, asthma, and increased risks of cancer and heart disease. The smoke produced by incense burning contains toxic and irritant compounds, including carcinogens such as PAHs, carbonyls, and benzene.
To mitigate the health risks associated with particulate matter from incense burning, several measures can be implemented. These include improving ventilation, using N95 masks, and utilizing air purifiers with HEPA filters and carbon filters to remove particulate matter and dangerous gases from the air.
