Protecting Our Kids: Fighting Air Pollution

Air pollution is a complex mix of pollutants, including fine particles and harmful gases like nitrogen dioxide, sulfur dioxide, and carbon monoxide. These pollutants can cause severe damage to health, especially in children. Young children breathe more rapidly than adults, taking in more air relative to their body weight, and their bodies are still developing, making them more vulnerable to the adverse effects of air pollution. Air pollution can cause respiratory problems, alter physical and cognitive development, and increase the risk of childhood disorders, cancer, and chronic diseases later in life. It is also linked to an increased risk of childhood leukemia and accounts for a significant number of newborn and child deaths worldwide.

Outdoor air pollution: caused by vehicles, power plants, factories, and industrial facilities

Outdoor air pollution is a serious issue that can have detrimental effects on children's health and well-being. It is caused by various sources, including vehicles, power plants, factories, and industrial facilities. These sources release pollutants into the atmosphere, which can have far-reaching consequences.

Vehicles, such as cars, trucks, and buses, contribute significantly to outdoor air pollution through their emissions. These emissions contain harmful gases, such as carbon dioxide, carbon monoxide, nitrogen oxides (NOx), and sulfur oxides (SOx), which are formed during the combustion of fossil fuels. Vehicle emissions are a primary source of what is known as particulate matter (PM), which includes fine particles like sulfates, nitrates, and mineral dust. PM 2.5, a subset of PM, is of particular concern as it is thin enough to be inhaled deeply into lung tissue, causing serious health issues.

Power plants, particularly those burning fossil fuels like coal, are another major contributor to outdoor air pollution. The retirement of coal-powered plants has been linked to decreased air pollution and reduced mortality risks. Studies have found that exposure to PM2.5 from coal is associated with an increased risk of various health issues, including respiratory diseases, cardiovascular disease, and even cancer.

Factories and industrial facilities also play a significant role in outdoor air pollution. Industrial processes, such as oil and gas development, and the burning of fossil fuels, release pollutants into the atmosphere. This includes not only gaseous emissions but also particulate matter, which can have detrimental effects on human health, especially that of children.

Children are more vulnerable to the adverse effects of air pollution due to their developing lungs and immature immune systems. Air pollution has been linked to various health issues in children, including respiratory problems such as asthma and bronchitis, as well as potential cognitive and emotional problems. Protecting children from outdoor air pollution involves taking steps to reduce their exposure and improving their overall health. This can be achieved by encouraging the use of cleaner fuels and technologies, promoting physical activity and a healthy diet, and educating children about the risks and solutions associated with air pollution.

Indoor air pollution: caused by cooking, smoking, cleaning supplies, and building materials

Indoor air pollution is a significant concern, especially as it can be an even greater threat to children than outdoor pollution. Cooking, smoking, cleaning supplies, and building materials can all contribute to poor indoor air quality. Here are some ways to reduce indoor air pollution and its potential harm to children:

Causes and Prevention of Indoor Air Pollution from Cooking

The World Health Organization warns that one-third of people worldwide use cooking methods that may be detrimental to their health. Combustion stoves, such as gas stoves, release more harmful particles than electric stoves. Gas stoves without proper ventilation are a significant source of particulate matter, including nitrogen oxide (NOx) and carbon monoxide (CO). NOx can cause chronic lung disease, severe asthma symptoms, and respiratory illnesses in children. CO buildup can lead to poisoning symptoms and, if untreated, even death. To mitigate these risks, ensure proper ventilation when cooking, especially when using a gas stove. Use exhaust fans or hoods, and consider grilling or barbecuing outdoors. Additionally, the type of cooking can influence pollution levels; frying and deep-frying release high amounts of particulate matter, so consider alternative cooking methods when possible.

Smoking and Secondhand Smoke

Smoking is a significant source of indoor air pollution, particularly due to secondhand smoke. Secondhand smoke contains over 7,000 chemicals, including formaldehyde, acetaldehyde, benzene, and particulate matter. These chemicals can persist in the air and surfaces even after smoking has stopped. To protect children from the harmful effects of secondhand smoke, it is crucial to implement strict smoking restrictions indoors. Ensure smokers go outside and away from windows or doors to smoke, and consider implementing a smoke-free policy in your home or seeking support to quit smoking altogether.

Cleaning Supplies and Building Materials

Some cleaning supplies and building materials can release harmful chemicals into the air, contributing to indoor air pollution. Volatile organic compounds (VOCs) are commonly found in cleaning products, paints, and solvents. Formaldehyde, a known carcinogen, can be released from pressed wood products, furniture, and building materials. To reduce exposure, opt for natural cleaning products, avoid pesticides, and ensure adequate ventilation when using any potentially harmful substances. Regular cleaning can also help control pollutants like dust and mould, improving indoor air quality.

Other Sources and General Recommendations

Other sources of indoor air pollution include poor ventilation, mould, and the use of certain products. Improve ventilation by opening windows, installing air vents, or using mechanical ventilation systems. Maintain clean air ducts and inspect your home for mould, leaks, and sources of moisture. Be mindful of the potential release of harmful chemicals from building materials and furniture. Additionally, encourage children to learn about environmental issues and involve them in finding solutions to reduce air pollution in their local area.

Health risks: respiratory infections, asthma, cognitive issues, and cancer

Air pollution is the biggest environmental health risk factor for children, causing respiratory infections, asthma, cognitive issues, and cancer. It is a leading cause of child mortality, with around 7 million premature deaths annually, including 709,000 deaths in children under 5 years old in 2021. This represents 15% of all global deaths in children under five, with more than 70% of these deaths linked to household air pollution from cooking with polluting fuels.

Children exposed to air pollution are at a higher risk of developing acute respiratory infections. Globally, pneumonia is the leading infectious disease causing paediatric mortality, especially in children under five years old. In 2019, pneumonia accounted for 14% of deaths in children under five and 22% of deaths in children aged 1-5. Almost half of all deaths due to lower respiratory tract infections in children under five are caused by particulate matter from household air pollution. In some countries in Africa and Asia, nearly one in every three lower respiratory infection deaths in children under five is linked to air pollution.

Air pollution also negatively impacts children's cognitive development and neurodevelopment. It can cause developmental delays and lifelong health issues. Studies have shown that children exposed to air pollution in the womb and early life are at an increased risk of respiratory symptoms and recurrent acute respiratory infections in the first 1-7 years of life.

Additionally, air pollution is linked to an increased risk of asthma in children. Exposure to pollutants such as PM2.5, PM10, and NO2 has been associated with the incidence of asthma and other atopic conditions in the first 3-6 years of a child's life. Children aged 11 and younger are more susceptible to adverse health effects from exposure to coarse PM due to their developing respiratory systems and the amount of time they spend outdoors.

Lastly, air pollution is associated with an increased risk of childhood cancer. Exposure to traffic-related air pollution has been linked to an increased risk of childhood leukaemia.

Protecting children: masks, healthy diet, and keeping them indoors when pollution is high

In areas with high levels of air pollution, such as East Asia and the Pacific, children are at a greater risk of suffering from its harmful effects. Their developing lungs and brains, weaker immune systems, and faster breathing rates make them especially vulnerable to the toxic particles in the air. As a result, it is crucial to take protective measures such as using masks, maintaining a healthy diet, and staying indoors when pollution levels are high.

One way to protect children from air pollution is to use masks that are designed to filter out pollutants. While the WHO doesn't have specific recommendations on mask use for children, it's best to consult a healthcare provider for advice based on factors like the child's age, health, and local air quality. Some masks, such as the Airinum Urban Air Mask 2.0, offer advanced protection and breathability with adjustable features for a snug fit. They are designed to protect against air pollution, smog, pollen, allergens, and bacteria, providing peace of mind for parents concerned about their children's health.

Maintaining a healthy diet is another crucial aspect of safeguarding children from the adverse effects of air pollution. A diet rich in vitamins C and E, as well as omega-3 fatty acids, can bolster children's overall health and help them cope with the challenges posed by polluted air. Vitamin C-rich foods include guava, papaya, pineapple, and citrus fruits, while vitamin E can be found in nuts, seeds, and green leafy vegetables like spinach and broccoli. Omega-3 antioxidants are abundant in seafood, fish, seaweed, walnuts, and flaxseeds.

Additionally, staying indoors when air pollution levels are high can be an effective protective measure. By regularly checking air quality information through local news, government websites, or apps, parents can make informed decisions about their children's activities. When outdoor pollution is particularly severe, adjusting schedules to minimize time outside or planning outings during times of lower pollution can significantly reduce children's exposure to harmful pollutants.

While staying indoors can provide some protection, it is important to recognize that indoor air pollution is also a significant concern. Sources such as tobacco smoke, wood-burning stoves, cleaning supplies, paints, and building materials can introduce toxic chemicals and particles into the indoor environment. To mitigate this, ensure that smoking does not occur indoors or near children, and consider investing in an air purifier with HEPA filters to absorb indoor pollutants.

Reducing pollution: using cleaner fuels, public transportation, and joining environmental initiatives

While it is impossible to eliminate children's exposure to air pollution entirely, there are still effective measures that can be taken to reduce it and protect them from the worst effects. One of the most significant sources of air pollution is the burning of fossil fuels and biomass fuels in vehicles, power plants, factories, and industrial facilities. To combat this, we can transition to cleaner, renewable energy sources and encourage the use of public transportation.

Using cleaner fuels, such as compressed natural gas (CNG) instead of diesel, can significantly reduce greenhouse gas emissions. For example, KCATA, a public transportation provider, reduced its greenhouse gas emissions by 1,870 metric tons by switching to CNG, which is equivalent to taking 395 passenger cars off the road for a year.

Public transportation not only reduces emissions but also congestion. In 2011, public transportation use in the US saved 865 million hours in travel time, and without it, congestion costs would have increased by $21 billion. Additionally, a person who switches from a 20-mile solo commute by car to public transportation can reduce their annual CO2 emissions by over 48,000 pounds, which is a significant contribution to lowering carbon dioxide emissions.

Joining environmental initiatives is another powerful way to combat air pollution. Tree-planting programs improve air quality while also cooling cities and creating habitats for wildlife. Community gardening and urban agriculture projects promote sustainable farming practices and reduce carbon footprints by minimizing transportation needs. Beach and river cleanups are also essential, as they prevent plastics from entering the sea and educate people about the dangers of single-use plastics.

At the grassroots level, supporting local renewable energy initiatives and joining renewable energy co-ops can help develop green energy infrastructure, lower energy costs, and reduce carbon emissions. This can be done by investing in co-ops, installing solar panels, or advocating for renewable energy policies. By taking these collective actions, we can make a significant difference in reducing air pollution and protecting children's health.
