Teens Polluting Air: Unknowingly Harming The Environment

Air pollution is a pressing issue that affects everyone, but children and teenagers are particularly vulnerable. This is due to a variety of factors, including their higher breathing rates, proximity to ground-level pollutants, and developing bodies and organs. As such, it is important to understand how teens may inadvertently contribute to air pollution and its adverse effects on their health. While teens may not be able to directly influence air quality policies, awareness of the issue can help them make informed decisions to reduce their exposure and contribution to air pollution.

Teens and children are more vulnerable to air pollution

Air pollution is a global health crisis that poses a serious threat to children and teens. While it affects people of all ages, children and adolescents are particularly vulnerable due to various factors. Firstly, their bodies, organs, and immune systems are still developing, making them more susceptible to the harmful effects of pollutants. Their lungs, for instance, are more permeable, and exposure to air pollution can hinder their growth and development, leading to respiratory issues such as asthma and reduced lung function.

Children and teens have higher breathing rates than adults and take in more air per kilogram of body weight. Their shorter height also means they breathe air closer to the ground, where pollutants from traffic exhausts and other sources are emitted and become concentrated. This results in a higher acquired dose of pollution, which is further exacerbated by their tendency to breathe through their mouths, allowing pollution to penetrate deep into the lower respiratory tract.

The impact of air pollution on children and teens is evident in the increased risk of various health issues. For example, air pollution is associated with low birth weight, asthma, respiratory infections, allergies, and an increased risk of adult chronic diseases. It is estimated that over 1,200 deaths in people under 18 years of age are caused by air pollution each year in EEA member and collaborating countries. Additionally, air pollution has been linked to negative effects on mental health, with studies showing that living in areas with dirty air can intensify feelings of stress and anxiety in teens.

Furthermore, air pollution has been associated with delinquent behaviour in teens. Studies have found a link between higher levels of air pollution and increased delinquency among 9- to 18-year-olds in urban neighbourhoods. Poor parent-child relationships, parental mental health issues, and social distress can compound these negative behavioural outcomes. The specific mechanisms behind these associations are still being investigated, but it is suspected that exposure to certain pollutants may cause inflammation in the brain or interfere with neural network connections, leading to adverse behavioural outcomes.

It is important to note that children and teens often have limited agency in improving their air quality or influencing policies to protect themselves. Therefore, it is the responsibility of adults, policymakers, and society as a whole to prioritize their health and well-being by implementing measures to reduce air pollution and minimize their exposure to harmful pollutants.

Outdoor air pollution sources

Vehicle Exhaust Emissions:

Vehicle exhaust fumes are a major contributor to outdoor air pollution, particularly in urban areas. Traffic emissions, including those from cars, buses, trucks, and motorcycles, release harmful pollutants such as nitrogen oxides, particulate matter (PM2.5), carbon monoxide, and volatile organic compounds. These emissions can lead to the formation of ground-level ozone, a major component of smog, which can irritate the lungs and exacerbate respiratory issues like asthma.

Industrial Activities:

Factories and power plants emit a range of pollutants into the atmosphere, including carbon dioxide, nitrogen oxides, sulfur dioxide, and particulate matter. These emissions contribute to outdoor air pollution and can have detrimental effects on respiratory health. Industrial activities, such as burning fossil fuels for energy production, are a significant source of air pollution and can impact areas located downwind from these facilities.

Wildfires and Burning of Waste:

Wildfires release large amounts of smoke and particulate matter into the atmosphere, which can spread over vast distances and affect air quality in nearby regions. Additionally, the burning of household garbage, agricultural waste, or yard waste can also contribute to outdoor air pollution, particularly in rural or suburban areas.

Construction and Building Materials:

Certain building materials and construction activities can release harmful pollutants into the outdoor air. For example, the use of asbestos in older buildings or the release of toxic chemicals from paints, adhesives, and treated wood can impact air quality.

Outdoor Smoking:

Cigarette smoking in outdoor public spaces can expose teens to secondhand smoke and air pollution. This is particularly relevant in areas near schools, playgrounds, or other child-centric settings, where teens may be more susceptible to the harmful effects of tobacco smoke.

It is important to note that outdoor air pollution sources can vary depending on the region and specific environmental factors. Additionally, the combined effects of multiple pollution sources can further exacerbate the impact on the health and well-being of teenagers.

Indoor air pollution sources

While outdoor air pollution is a significant concern, it is also essential to address indoor air pollution, which can significantly affect the health and well-being of teenagers. Indoor air pollution sources can be divided into two main categories: outdoor sources that infiltrate indoor spaces and indoor-specific sources.

Outdoor air pollution can contribute to indoor air pollution, especially in homes with inadequate ventilation. This can occur when outdoor air is not adequately circulated indoors to dilute emissions from indoor sources, or when indoor air pollutants are not effectively removed from the home. High temperature and humidity levels can also increase indoor pollutant concentrations.

One of the most common indoor-specific sources of air pollution is building products and furnishings that release toxic chemicals. This includes building materials such as mineral fibres and legacy asbestos, which can still be found in older buildings. Improper attempts to remove asbestos can release asbestos fibres into the air, endangering the health of occupants. Additionally, some natural pollutants like radioactive radon, which is often present in the soil or rock on which homes are built, can infiltrate indoor spaces.

Other indoor-specific sources of air pollution include smoking, burning candles, allergens, and dust. Mould, in particular, is a frequent indoor health hazard that increases the risk of developing asthma, allergic rhinitis, and respiratory infections. Activities such as cleaning, redecorating, or engaging in certain hobbies can also release pollutants intermittently. Unvented or malfunctioning appliances, improperly used products, and improperly adjusted gas stoves can emit dangerous levels of pollutants, including carbon monoxide.

To mitigate the impact of indoor air pollution on teenagers' health, it is crucial to identify and address these sources. Improving indoor air quality can be achieved through proper ventilation, regular cleaning, and avoiding the use of toxic chemicals and pollutants indoors.

Ways to reduce air pollution

While air pollution affects everyone, children and teens are more vulnerable to its effects. They are at a higher risk of developing asthma, respiratory infections, and allergies, among other health issues. They are also more susceptible to the negative impacts of air pollution as their bodies, organs, and immune systems are still developing.

• Limit vehicle usage: Vehicle exhaust is a significant contributor to air pollution. Opt for carpooling, public transportation, biking, or walking whenever possible. Electric vehicles are also a more environmentally friendly alternative.
• Maintain your vehicle: Keep your car well-maintained and fix any exhaust or oxygen sensor problems promptly. Ensure your tires are properly inflated, as under-inflated tires can lower gas mileage and increase fuel consumption.
• Avoid idling: An idling engine, especially in buses and large trucks, creates a concentrated hotspot of pollution. Encourage schools and daycares to implement no-idling policies, and turn off your engine whenever possible.
• Reduce energy consumption: Choose energy-efficient appliances and heating systems, and turn off electrical appliances when not in use. This will not only reduce air pollution but also help conserve energy.
• Plant and care for trees: Trees act as natural air purifiers by absorbing carbon dioxide and releasing oxygen into the atmosphere. They also help cool the surrounding environment.
• Avoid backyard fires: Smoke from fires can negatively impact air quality, especially in cities with higher pollution levels. If you must have a campfire, keep it small and brief, and only burn dry firewood.
• Improve indoor air quality: Indoor air pollution can significantly affect health. Ensure proper ventilation in your home, avoid smoking indoors, and limit the use of candles, incense, and other sources of indoor air pollution.
• Support local initiatives: Engage with local businesses, city offices, and schools to promote sustainable practices and reduce their environmental impact. Encourage the adoption of programs that can help reduce air pollution and raise awareness about the issue.
• Promote green spaces: Urban areas with limited foliage tend to have higher levels of air pollution. Advocate for the development and preservation of parks and green spaces, which can help absorb pollutants and improve air quality.
• Educate teens about air pollution: Empower teens to make informed decisions about their health. Encourage them to track air quality through websites, apps, or weather reports, and to take necessary precautions, such as limiting outdoor activities during high-pollution periods.

By implementing these measures, we can work towards reducing air pollution and creating a healthier environment for teens and all members of society.

Effects of air pollution on teens

While air pollution affects everyone, children and adolescents are particularly vulnerable to its effects. This is due to a variety of factors, including their higher breathing rates, the fact that they take in more air per kilogram of body weight, and their lower physical height, which means they breathe air closer to the ground where some pollutants are more concentrated. Additionally, children and adolescents have developing organs and immune systems, which makes them more susceptible to the harmful effects of air pollution.

One of the main effects of air pollution on teens is the increased risk of respiratory problems and other health issues. Air pollution can cause and exacerbate asthma, respiratory infections, and allergies. It can also irritate the lungs and cause breathing problems, even leading to reduced lung function. Poor air quality can also increase the chances of getting respiratory infections, such as the flu, which can further complicate respiratory conditions like asthma.

Another effect of air pollution on teens is the potential impact on their mental health and well-being. Studies have shown that air pollution can intensify feelings of stress, especially in teens who already suffer from anxiety or depression. Teens living in areas with higher air pollution levels may experience increased stress reactivity, with physical symptoms such as increased heart rate and sweating. This heightened stress response can contribute to problems with both physical and mental health over time.

Air pollution has also been linked to delinquent behaviour in teens. Research suggests that ambient air pollution may increase delinquent behaviour among 9- to 18-year-olds, particularly in urban neighbourhoods with limited greenspace. Poor parent-child relationships, parental mental health issues, and social distress can further compound these effects. Scientists suspect that exposure to air pollutants may cause inflammation in the brain or interfere with neural network connections, leading to negative behavioural outcomes.

Furthermore, air pollution has been found to increase the risk of obesity in teens, particularly in urban areas with less foliage. This is significant as obesity itself is a risk factor for various health conditions and can impact overall well-being.

It is important to note that the effects of air pollution on teens are not limited to the short term. Air pollution during childhood can increase the risk of developing chronic diseases later in life. Therefore, it is crucial to address and reduce air pollution to protect the health and well-being of teens and adolescents.
