What You'll Learn
Increased risk of cancer
Air pollution is a significant health concern, threatening the health and lives of millions of people. It is linked to an increased risk of cancer, particularly lung cancer, and is a contributing factor to the rising number of cancer cases each year. While smoking is a more significant cause of lung cancer, air pollution is still a preventable risk factor that threatens progress in reducing cancer rates.
Outdoor air pollution is a mixture of tiny particles and substances in the air, including fumes from vehicles, factories, and smoke from burning fuels. It also includes natural sources of pollutants, such as wind-blown dust, radon, and ozone. Indoor air pollution, on the other hand, is primarily caused by second-hand smoke from cigarettes and burning wood or coal for heating or cooking.
Studies have found a link between exposure to air pollution and an increased risk of lung cancer. In the UK, outdoor air pollution is estimated to cause approximately one in ten cases of lung cancer. Additionally, air pollution is associated with a 36% higher mortality risk from lung cancer, with PM2.5 particulate matter playing a significant role. According to the World Health Organization (WHO), air pollution is responsible for nearly seven million deaths annually, with low- and middle-income countries bearing the brunt of premature deaths related to air pollution.
Air pollution is also linked to an increased risk of other types of cancers, including breast, liver, and pancreatic cancer. A study in Hong Kong and Birmingham, UK, found that long-term exposure to fine particulate matter, including PM2.5, increased the risk of mortality from these cancers. Additionally, air pollution may contribute to the development of cancer in the digestive organs by affecting gut microbiota.
Furthermore, air pollution is associated with an increased risk of cancer in certain vulnerable populations, including children, women, older adults, and low-income communities. Children exposed to high levels of air pollutants are more likely to develop bronchitis symptoms and experience stunted lung development, which can impact their health in adulthood. Prenatal exposure to air pollution has also been linked to an increased risk of cerebral palsy and neurobehavioral problems in children.

Respiratory issues
Air pollution has been linked to a variety of respiratory issues, which can be both short-term and long-term. Inhalation of particle pollution can induce inflammation in the respiratory tract, leading to a range of respiratory symptoms, including coughing, wheezing, and phlegm. This inflammation can cause a decrease in lung function, making it harder to breathe and potentially resulting in respiratory emergencies and hospitalizations. Constant exposure to air pollution can contribute to reduced respiratory function even in healthy individuals.
Particle pollution exposure is linked to an increased risk of developing asthma, with outdoor air pollution being associated with higher asthma prevalence and severity. Children exposed to air pollution during infancy have an increased risk of developing asthma and experiencing long-term respiratory consequences. Additionally, increased outdoor air pollution levels have been associated with more frequent use of rescue inhalers in asthmatic patients.
Air pollution also plays a role in the development and exacerbation of chronic obstructive pulmonary disease (COPD). It can trigger acute exacerbations of COPD, leading to more emergency room visits and hospitalizations. Particle pollution can further impair pulmonary function in COPD patients, and the inhalation of particulate matter can introduce microorganisms that contribute to frequent exacerbations.
Long-term exposure to air pollution can stunt lung development in children, harming their health in the present and reducing their lung function as adults. It also increases the risk of respiratory infections, especially in children. Prenatal exposure to air pollutants has been associated with an increased risk of cerebral palsy and adverse neurobehavioral outcomes in children.
The impact of air pollution on respiratory health is evident across all ages, with older adults being more susceptible due to a higher prevalence of pre-existing respiratory conditions and a gradual decline in physiological defenses. Transitioning to clean energy sources and reducing vehicle emissions are key strategies in improving air quality and mitigating the respiratory health risks associated with air pollution.

Cardiovascular issues
Air pollution is a dominant issue in the US, threatening the health and lives of millions of Americans. It is a known cause of over three million deaths every year due to ischaemic heart disease or stroke, which is more than traditional cardiac risk factors such as diabetes, smoking, or obesity.
Fine particulate matter, or particle pollution, is a primary cause of cardiovascular issues. These particles, known as PM2.5, are a mixture of solid particles and liquid droplets found in the air. Some examples include dust, dirt, soot, or smoke. PM2.5 can be released into the atmosphere through industrial emissions, brake and tire wear, resuspended soil and dust, wildfires and prescribed burns, and the burning of agricultural products, biomass, and coal.
When breathed in, these particles can travel deep into the bloodstream through the lungs and to the heart. This can increase the risk of developing heart and circulatory diseases. More specifically, air pollutants can damage blood vessels by making them narrower and harder, increasing blood pressure, and increasing the strain on the heart muscle. They can also affect the heart's electrical system, causing abnormal heart rhythms, and even cause small changes to the structure of the heart, similar to changes seen in the early stages of heart failure.
For people with existing heart and circulatory conditions, the damage can increase their risk of a heart attack or stroke. Evidence suggests that short- and long-term exposure to particle pollution has been shown to increase hospitalizations for serious cardiovascular events, particularly in people with established heart disease. These events include coronary syndrome, arrhythmia, heart failure, stroke, and sudden cardiac death.

Developmental damage
Poor air quality and air pollution are detrimental to human health and can cause a variety of health issues. One of the most concerning impacts of air pollution is its ability to cause developmental damage, particularly in children.
Lung Development
Air pollution can slow and stunt lung development in children, affecting their health in the present and reducing their lung function in adulthood. Children exposed to high levels of air pollutants are more likely to develop lung problems and bronchitis symptoms in adulthood. Studies have shown that air pollutants, particularly ozone and PM2.5, are linked to asthma-related changes in children's airways. Additionally, children living in low-income urban areas tend to have higher rates of asthma due to increased exposure to outdoor air pollution.
Brain Development
Exposure to fine particulate matter, such as PM2.5, can have adverse effects on brain development. Even at relatively low levels, PM2.5 can alter the size of a child's developing brain, increasing the risk for cognitive and emotional problems during adolescence. Prenatal exposure to air pollutants, including PAHs, has been associated with slower processing speed, attention-deficit and hyperactivity disorder (ADHD) symptoms, and other neurobehavioral issues in urban youth.
Prenatal Health
Air pollution exposure during pregnancy can have severe consequences for both the mother and the fetus. It increases the risk of hypertensive disorders, which are a leading cause of pre-term birth, low birth weight, and maternal and fetal illness and death. Additionally, prenatal exposure to PM2.5 has been linked to an increased risk of cerebral palsy in newborns.
Cardiovascular Health
Air pollution can also impact cardiovascular health and development. Exposure to TRAP, or traffic-related air pollution, can lower levels of high-density lipoprotein (good cholesterol) and increase the risk of cardiovascular disease. Fine particulate matter, such as PM2.5, can impair blood vessel function and accelerate the calcification of arteries.
The developmental damage caused by air pollution has severe and long-lasting impacts on the health and well-being of children and adolescents. It is crucial to address air quality issues and implement measures to reduce pollution levels to protect the vulnerable population from these harmful effects.

Mental health concerns
Air pollution has been linked to a variety of mental health concerns, with research indicating that it can have a significant impact on brain function and mental well-being.
One of the key mental health risks associated with air pollution is the increased likelihood of developing anxiety and depression. Studies have found that exposure to polluted air is linked to changes in brain regions that control emotions, resulting in a higher risk of these mental health disorders. This is supported by research from Harvard, which identified a connection between air pollution and an increased risk of dementia, a neurodegenerative condition.
Furthermore, air pollution has been associated with higher stress levels and psychological distress. This is potentially due to the impact of pollution on stress hormones and inflammation in the brain. Short-term exposure to severe air pollution has been linked to an increased risk of hospitalisation for mental health crises, indicating a possible exacerbation of existing mental health conditions.
The impact of air pollution on mental health is particularly concerning for children and adolescents, who are in critical periods of brain development. Studies have found that exposure to air pollution during prenatal and early life stages is associated with an increased risk of cerebral palsy, ADHD, and other neurobehavioral problems.
While the exact mechanism between air pollution and mental health is not fully understood, the growing body of evidence suggests that air pollution is a contributing factor to the mental health challenges faced by individuals and societies.
