Air pollution is anything that makes the air more toxic and damaging to our health. Air pollution can affect all parts of our bodies, including the health of our lungs, heart, and brain. Some of the most damaging types of air pollution include particulate matter, nitrogen dioxide, ozone, and sulphur dioxide. These pollutants can increase the risk of lung cancer, COPD, cardiovascular disease, and respiratory infections. Children are especially vulnerable to the effects of air pollution, as their lungs are still developing and they breathe faster, taking in more polluted air.
| Characteristics | Values |
|---|---|
| Pollutants that can damage lungs | Particulate matter (PM), nitrogen dioxide, ozone, sulphur dioxide, nitrogen oxides, wood smoke |
| Health effects | Asthma, COPD, cardiovascular disease, lung cancer, respiratory infections |
| Risk factors | Children are more at risk than adults due to developing lungs and faster breathing |
What You'll Learn
Nitrogen dioxide
Children are particularly vulnerable to the effects of nitrogen dioxide and other air pollutants. Their lungs are still developing, and they breathe faster, taking in more polluted air. As a result, exposure to air pollution during childhood can increase the risk of developing asthma and COPD in adulthood.
The impact of nitrogen dioxide on lung health is a global concern, affecting both developing and developed countries. It is crucial to address air quality issues through multi-national cooperation involving governments, industries, energy-based enterprises, and the public. By working together, we can mitigate the harmful effects of nitrogen dioxide and other air pollutants on our lung health and overall well-being.

Ozone
Research has shown that mice exposed to ozone produced high amounts of hyaluronan in their lungs. Hyaluronan is a sugar that plays a central role in the response to lung injury. Scientists have found that they can protect mice from the effects of ozone by pretreating them with a protein that binds hyaluronan.
The health effects of ozone exposure can vary widely among individuals, even when the dose and duration of exposure are the same. However, children are generally more at risk than adults because their lungs are still developing, and they breathe faster, taking in more polluted air.

Sulphur dioxide
From 1 January 2025, the Environmental Protection (Air) Amendment Policy 2024 (EPP Air) objectives for sulphur dioxide are: 0.075 parts per million (ppm) for a 1-hour exposure period. These guidelines are designed to protect sensitive individuals, such as children and asthmatics.

Particulate matter
Breathing in particulate matter can play a part in the development of lung cancer. Over time, breathing in fine particles in the air increases the chances of developing chronic obstructive lung disease (COPD), chronic bronchitis, cardiovascular disease, or lung cancer. In high concentrations, wood smoke can permanently damage lung tissue.
Children are more at risk than adults because their lungs are still developing. They also breathe faster, which means they take in more polluted air. Being exposed to pollution as a child increases the risk of developing asthma and COPD as an adult.

Wood smoke
One study focused on New Mexican smokers aged 40 and older, assessing the health impact of self-reported "ever WS exposure for over a year". The study used objective measures such as lung function decline, lung cancer incidence, and deaths, as well as health-related quality-of-life questionnaires. The results indicated that wood smoke exposure affects lung aging, quality of life, and all-cause mortality in this population.
Additionally, wood smoke contributes to the outdoor levels of carbon monoxide and increases indoor concentrations. Carbon monoxide is a harmful gas that can have detrimental effects on human health, particularly when inhaled in enclosed spaces. Wood smoke also contains nitrogen oxides, which are harmful both indoors and outdoors, and contribute to particle pollution.
The pollutants in wood smoke, including volatile organic compounds, can worsen air quality and have negative impacts on human health. It is important to be aware of the potential dangers of wood smoke exposure, especially for individuals with pre-existing respiratory conditions or those who are at a higher risk of developing lung-related diseases.

Frequently asked questions
Particulate matter, nitrogen dioxide, ozone, and sulphur dioxide are particularly damaging types of air pollution.
Particulate matter can penetrate the lung epithelium and cause inflammation, worsening pre-existing lung conditions and exacerbating symptoms of asthma and chronic obstructive pulmonary disease (COPD).
Children are more at risk than adults because their lungs are still developing. They also breathe faster, which means they take in more polluted air. Being exposed to pollution as a child increases the risk of developing asthma and COPD as an adult.
