FAQs on Pollution-Free Cities in India
AQI (Air Quality Index) is a measure of air pollution levels. A lower AQI indicates cleaner air, which is healthier for residents and contributes to a better quality of life. An AQI below 50 is considered good, while levels above 150 are considered unhealthy.
Factors like limited industrial activity, abundant greenery, community-driven cleanliness efforts, and environmental awareness contribute significantly to low pollution levels. Geographical advantages like coastal or elevated locations also help maintain cleaner air.
India uses a standard AQI scale to monitor air quality. Sensors across the country measure pollutant levels like PM2.5, PM10, nitrogen dioxide, sulfur dioxide, and ozone, which are then converted into an AQI score.
Delhi, Mumbai, and other major cities face high pollution due to dense traffic, industrial activity, construction, and population density, which result in higher emissions and deteriorating air quality.
A low AQI reduces the risk of respiratory illnesses, asthma, and cardiovascular issues. It contributes to a healthier environment, especially for children, the elderly, and individuals with pre-existing health conditions.
Yes, greenery helps absorb pollutants like carbon dioxide and particulate matter, improving air quality. However, effective waste management, reduced emissions, and clean energy initiatives are also necessary to maintain low pollution levels.
These cities focus on sustainable practices, including clean energy usage, waste management, green infrastructure, and environmental education. Strong local government policies and community support also play a critical role.
Local governments implement and enforce environmental regulations, promote waste management practices, develop green spaces, and conduct awareness campaigns, all of which help in controlling pollution levels.
PM2.5 refers to particulate matter smaller than 2.5 microns in diameter, which can penetrate the lungs and bloodstream, causing severe health issues. It’s a major pollutant in urban areas and a crucial component in AQI measurement
To reduce AQI levels, cities can adopt eco-friendly transportation, promote clean energy, increase green cover, enforce strict industrial emissions standards, and engage citizens in environmental initiatives.
