Who Suffers Most From Fine Particle Air Pollution?

Fine particle air pollution, also known as particulate matter or soot, is a mix of tiny solid and liquid particles in the air. These particles are so small that they can travel deeply into the respiratory tract, reaching the lungs, and causing serious health issues. While everyone is at risk, certain groups are more vulnerable to the health impacts of fine particle air pollution. This includes children, pregnant women, the elderly, and people with pre-existing health conditions such as cardiovascular and respiratory diseases, including asthma. People of colour are also more vulnerable, particularly those living near emission sources.

People with respiratory diseases

Those with pre-existing respiratory diseases are at greater risk of potential respiratory-related health effects due to short-term particle exposures. Long-term exposure to fine particles has been linked to increased respiratory symptoms and a higher risk of respiratory-related hospitalizations and premature mortality, especially in those with chronic lung diseases. Research has also found an association between exposure to fine particle pollution and an increased risk of lung cancer, even in those who have never smoked.

The impact of fine particle air pollution on individuals with respiratory diseases can vary depending on the specific disease and its severity. For example, people with asthma may experience worsened symptoms and increased medication use, while those with chronic obstructive pulmonary disease (COPD) may suffer from additional systemic inflammation, impacting their quality of life.

It is crucial for people with respiratory diseases to limit their exposure to fine particle air pollution. They can do so by monitoring air quality and staying indoors when particle pollution levels are high. Using air purifiers or air conditioners that recirculate air can also help reduce indoor particle levels. Additionally, individuals with respiratory diseases should prioritize living in areas with better air quality and avoid proximity to emission sources, as those living near these sources are at higher risk of the harmful effects of particle pollution.

Overall, people with respiratory diseases are a vulnerable group that experiences unique challenges due to fine particle air pollution. By understanding their increased risks and taking proactive measures to limit exposure, they can better protect their health and well-being.

Pregnant women

Exposure to fine particle air pollution is dangerous for everyone, but some groups are more vulnerable to its effects than others. These include children, pregnant women, the elderly, and people with asthma, respiratory diseases, or cardiovascular diseases.

The fetus is highly susceptible to environmental contaminants during pregnancy as it is developing, and exposure to air pollution can have a major, lasting impact. Fine particle air pollution can breach the placenta, leading to an increased risk of asthma in the child later in life. Metal buildup in the placenta due to air pollution can also limit the fetus's growth, resulting in preterm birth, increased gestational diabetes, reduced chromosomal stability, and other health and developmental issues.

Research has also found that exposure to fine particle air pollution during pregnancy can cause altered immune responses in pregnant women, leading to adverse birth outcomes. Increased inflammation has been observed in both mothers and fetuses, corresponding with negative pregnancy outcomes.

To protect maternal and fetal health, it is important for pregnant women to minimize their exposure to air pollution, especially during the early and late stages of pregnancy. This can be achieved by limiting time spent outdoors on days with high particle pollution levels, using air purifiers indoors, and implementing measures to reduce exposure to indoor air contaminants, such as using natural household cleaners and vent hoods when cooking.

People of colour

Exposure to fine particle air pollution can cause serious health issues, including heart and lung problems, and even premature death. While everyone is at risk, certain groups are more vulnerable to the harmful effects of this type of pollution. One of the most notable at-risk groups is people of colour.

There are several reasons why people of colour may be more vulnerable to fine particle air pollution. One factor is residential segregation, which has resulted in many racial and ethnic minorities living in areas with higher levels of pollution. Pollution sources, such as industrial sites, power plants, and vehicles, tend to be located near disadvantaged communities, increasing the exposure of people of colour to harmful pollutants. Additionally, historical housing policies and systemic racism have contributed to the concentration of people of colour in areas with higher pollution levels.

Furthermore, people of colour may also face greater health risks due to underlying health conditions, limited access to healthcare, and socioeconomic factors. Existing health disparities, such as higher rates of diabetes or respiratory diseases among certain racial and ethnic groups, can exacerbate the impact of air pollution on their health. Additionally, socioeconomic factors, such as limited access to healthy foods, quality education, and well-paying jobs, can further increase the vulnerability of people of colour to the harmful effects of fine particle air pollution.

The disparities in exposure to fine particle air pollution have serious public health implications. Studies have linked increased exposure to higher rates of cardiovascular and respiratory issues, as well as increased mortality among people of colour. The higher vulnerability of this group to the harmful effects of air pollution underscores the need for effective regulations and policies that address environmental injustices and ensure equal protection for all communities.

Children

The impact of air pollution on children's health can be both immediate and long-lasting. Short-term exposure to fine particles can cause eye, nose, throat, and lung irritation, coughing, sneezing, a runny nose, and shortness of breath. It can also exacerbate underlying health conditions, such as asthma. In the long term, air pollution exposure can negatively affect children's physical and cognitive development, increasing their risk of chronic diseases like cardiovascular disease and asthma later in life.

To protect children from the harmful effects of fine particle air pollution, it is essential to reduce their exposure. This can be achieved by monitoring air quality and minimizing the time spent in areas with high pollution levels, especially near traffic congestion or industrial pollution sources. When air pollution levels are high, it is recommended to limit children's strenuous activity and outdoor play. Improving air quality around schools and child-centric settings is crucial, as children spend significant time indoors and outdoors in these environments.

It is also important to raise awareness among children about the risks of air pollution and encourage them to participate in environmental activities. UNICEF's Voices of Youth community and the Breathe Life 2030 global campaign for clean air are excellent resources for children to learn about these issues and take proactive steps towards a healthier future.

Elderly people

The impact of air pollution on elderly individuals is not limited to physical health. Research has linked air pollution to decreased cognitive performance in older adults. Poor air quality can also negatively affect mental health, with studies suggesting that air pollution may contribute to mental disorders. However, it is important to note that physical activity, even in polluted environments, can still provide some benefits to older adults, particularly in maintaining mental health and cognition.

To protect elderly individuals from the harmful effects of fine particle air pollution, it is recommended to stay indoors when particle pollution levels are high. Using air conditioners or air purifiers can help reduce indoor particle levels. In areas with air quality alerts, such as New York State, it is important to pay attention to these warnings and take appropriate precautions. Additionally, on a broader scale, transitioning to renewable forms of energy and reducing emissions, especially in the transport sector, are crucial steps to improve air quality and protect vulnerable populations, including the elderly.
