Delhi's Air Pollution: Strategies For A Cleaner Tomorrow

Delhi, the capital territory of India, has been ranked as the most polluted city in the world. The air pollution in Delhi is so severe that it has irreversibly damaged the lungs of 2.2 million children. The air quality index (AQI) in Delhi generally falls within the 'Satisfactory' and 'Moderate' ranges between March and September, but then deteriorates to 'Poor', 'Severe', or even 'Hazardous' levels between October and February. The main contributors to Delhi's air pollution are vehicular emissions, industrial emissions, dust, crop burning, thermal power plants, and road dust. To prevent air pollution in Delhi, urgent actions are required from both the administration and citizens. Some measures to reduce air pollution include the adoption of electric vehicles, carpooling, the use of bicycles, improving road infrastructure, encouraging shared taxi services, implementing strict actions under the Graded Response Action Plan (GRAP), installing solar panels, improving landfill management, and planting trees. Additionally, individuals can protect themselves by wearing N95/99 masks, staying indoors when air quality is poor, improving indoor ventilation, and consuming a balanced diet rich in vitamins and antioxidants.

How to prevent air pollution in Delhi

Wear N95/99 masks to filter out particulate matter

Delhi's air pollution is a severe issue, with the territory's air quality deemed the worst of any major city globally. The high levels of pollution are caused by several factors, including vehicular emissions, dust, industrial emissions, and crop stubble burning. This has led to a public health crisis, causing respiratory issues and irreversible lung damage, especially in children.

To protect oneself from the harmful effects of air pollution in Delhi, it is essential to wear a well-fitting mask that filters out particulate matter. N95 and N99 masks are effective options, capable of filtering out 95% and 99% of particulate matter, respectively. These masks are particularly useful when venturing outdoors, where exposure to harmful pollutants is more significant.

When selecting an N95 or N99 mask, it is crucial to consider the filter size and ensure it can filter out particles smaller than 2.5 microns, which are the most damaging to health. A proper fit is also vital, as the mask should snugly cover the nose and mouth to be effective. While these masks do not protect against oil-based pollutants, they are still recommended for protection against severe pollution.

It is important to note that N95 and N99 masks are disposable and should be discarded after a few days or when they become soiled or distorted. Additionally, they should not be shared to prevent the risk of transferring infections. While these masks offer significant protection, they are not a complete guarantee against respiratory issues or viral infections, and other preventive measures, such as maintaining ventilation at home and a healthy diet, should also be followed.

Avoid outdoor exercise when pollution levels are high

Delhi's air pollution is a serious issue, with the territory's air quality deemed the worst of any major city in the world. The poor air quality has had irreversible effects on the lungs of 2.2 million children. As such, it is important to take steps to protect yourself when pollution levels are high, such as avoiding outdoor exercise.

Outdoor exercise is not recommended when pollution levels are high, even with a mask, as it can still disrupt your breathing patterns and leave you breathless or dizzy. Even healthy people with no history of respiratory issues are reporting lung infections and other respiratory issues due to the increased levels of pollution. Therefore, it is best to stay indoors and exercise inside your home or at the gym. If you have no other option but to exercise outdoors, it is important to check the Air Quality Index (AQI) and only train when the AQI is under 200. You should also reduce the intensity and volume of your workout and stick to low-intensity exercises.

If you do decide to exercise outdoors when pollution levels are high, it is important to take precautions to minimise your exposure to pollutants. This includes choosing the right time, location, and protective gear. It is best to exercise early in the morning, as the air quality tends to deteriorate after 7 am due to vehicular movement. However, pollution tends to be at its peak in the early morning, so it is important to check the AQI before heading out. There are many apps available that can help you monitor the AQI in your area. It is also important to choose a location that is away from major traffic intersections and industrial areas, as these areas tend to have higher levels of pollution. Parks and green spaces often have better air quality due to the presence of trees, which act as natural air filters.

In addition to the right time and location, wearing a high-quality pollution mask is essential when exercising outdoors in Delhi. Look for masks that are designed to filter out fine particulate matter (PM2.5) and other pollutants, such as N95 or N99 masks. When purchasing a mask, consider the filter size and ensure it fits snugly over your nose and mouth. It is also important to track your heart rate when wearing a mask and stay in lower heart rate zones (Zone 1 and 2) throughout your workout. Avoid HIIT workouts or any intense exercises that require a lot of air and oxygen.

While exercising outdoors in Delhi when pollution levels are high is not recommended, it is possible to minimise your exposure to pollutants and continue your fitness routine with the right precautions. However, always prioritise your health and be mindful of any respiratory symptoms. If you experience coughing, wheezing, or shortness of breath, stop exercising immediately and seek medical advice if necessary.

Improve ventilation when cooking, cleaning, or opening new furniture

When cooking, cleaning, or opening new furniture, electronics, or other items that may emit VOCs, it is important to maximise ventilation to prevent air pollution. Here are some ways to improve ventilation in these scenarios:

Cooking

Cooking, especially with gas stoves, can release pollutants such as NO2, benzene, and carbon monoxide. To prevent the build-up of these harmful gases and particles, it is important to use proper exhaust ventilation. Here are some ways to improve ventilation while cooking:

• Use a range hood (kitchen exhaust) that ducts air outside. Ducted range hoods are more effective than ductless or recirculating hoods in removing pollutants.
• Ensure the range hood is set to the maximum airflow setting.
• Lower the cooking heat when possible and fry and broil less often.
• Regularly clean and maintain the metal screens of the range hood according to the manufacturer's instructions.
• If you do not have a range hood, open nearby windows or doors to create a breeze and improve airflow.
• Use a portable window fan to pull the air out of the room.
• Replace gas stoves with electric stoves to reduce gas-specific pollutants.

Cleaning

When cleaning, especially with the use of chemicals, it is important to improve ventilation to prevent the build-up of indoor air pollutants. Here are some ways to improve ventilation while cleaning:

• Open windows and doors to create natural ventilation.
• Use ceiling fans or portable window fans to improve airflow and pull the air out of the room.

Opening New Furniture

When opening new furniture, it is important to be aware of potential VOC emissions. Here are some ways to improve ventilation when opening new furniture:

• Prior to opening new furniture, especially in enclosed spaces, maximise ventilation by opening windows and doors.
• Use fans to improve airflow and dilute any potential VOC emissions.

In general, improving ventilation by bringing in fresh, outdoor air can help create healthier indoor air. However, it is important to note that outdoor air can also be polluted, especially in areas with high levels of outdoor air pollution. Therefore, it is crucial to pair ventilation with other measures to reduce indoor air pollution, such as source control and air cleaning.

Consume vitamin C-rich fruits, magnesium-rich meals, and omega-rich foods

Delhi's air pollution is a serious issue, with the Indian capital's air quality deemed the worst of any major city in the world. The air pollution affects the surrounding districts, too, and is estimated to cause around 2 million deaths per year across India.

One way to protect yourself from the harmful effects of air pollution is to consume vitamin C-rich fruits, magnesium-rich meals, and omega-rich foods. Vitamin C is abundant in citrus fruits such as oranges, tangerines, lemons, and Indian gooseberries. These fruits offer a generous dose of antioxidants, which help to neutralise the free radicals produced by pollutants and boost your overall immunity. Vitamin C is also known to brighten dull skin.

Magnesium-rich foods include green vegetables such as broccoli, spinach, fenugreek, and kale. These vegetables also contain beta carotene, zeaxanthin, lutein, and sulforaphane, which all benefit the immune system.

Omega-rich foods include healthy seeds and nuts such as pumpkin seeds, sesame seeds, chia seeds, flaxseed, walnuts, peanuts, and almonds. Omega fatty acids are crucial for overall health and can only be obtained from food since the body doesn't naturally produce them. They reduce the risk of inflammation, while vitamin E, also found in nuts and seeds, maintains eye and skin health.

In addition to consuming these nutrient-rich foods, it is important to take other steps to protect yourself from Delhi's air pollution. When pollution levels are high, strenuous physical activity and even leisurely walks outside should be avoided, as they increase the rate of breathing and, therefore, exposure to harmful air and contaminants. It is also recommended to wear an N95/99 mask whenever you step outside, as particles smaller than 2.5 microns are both damaging and dangerous.

• Public Awareness Campaigns: Launch campaigns to educate the public about the benefits of carpooling, including reduced traffic, lower fuel costs, and decreased emissions. Encourage citizens to carpool with friends, colleagues, and family whenever possible.
• Workplace Initiatives: Businesses and organizations should be encouraged to implement carpool programs for their employees, offering incentives such as preferred parking spots for carpoolers or providing ride-sharing subsidies.

Safe Bicycle Lanes:

• Designated Bicycle Lanes: Create dedicated bicycle lanes on all roads in Delhi, including residential areas. These lanes should be clearly marked and separated from motorized traffic, providing a safe space for cyclists.
• Traffic Calming Measures: Implement traffic-calming measures, such as speed bumps, roundabouts, and reduced speed limits, to discourage high vehicle speeds and volumes, making the roads safer for cyclists.
• Infrastructure Improvements: Invest in better road infrastructure, such as well-maintained bicycle-friendly roads, improved signage, and bicycle-specific traffic signals, to enhance the safety and convenience of cyclists.
• Promote Cycling Culture: Encourage a culture of cycling by organizing community events, such as bike-to-work days, group rides, and cycling workshops. This will help normalize cycling as a healthy, environmentally friendly mode of transportation.
• Incentivize Cycling: Offer incentives to cyclists, such as providing secure bike parking facilities, offering discounts or rewards for those who cycle to work, and implementing a bike-sharing program with easily accessible pick-up and drop-off locations.

By encouraging carpooling and creating safe bicycle lanes, Delhi can significantly reduce vehicle emissions, improve air quality, and foster a healthier and more sustainable environment for its residents. These measures are crucial steps towards addressing the city's air pollution crisis and ensuring the well-being of its citizens.
