But Delhi is also known for the worst air quality in the world. Delhi air quality index AQI is affecting the life expectancy of every Dilliwala. Every winter morning, Delhiites wake up with new alarming pollution levels that break previous records and set new positions.\u00a0Do you think Delhi will go through the same air pollution problems as in previous years? Will Delhiites&#8217; life expectancy drop again this year? Does air pollution again turn into a life-threatening issue in Delhi?<\/p>\n\n<p><strong>Shrinking your life expectancy with deteriorating <a href=\"https:\/\/www.aqi.in\/dashboard\/india\/delhi\/new-delhi\">Delhi <\/a>air quality index AQI:<\/strong><\/p>\n\n<p>Every year, air quality in Delhi is affecting the health of thousands of people. Waking up with a coughing throat, frequent headaches, throat infections and more asthma conditions are increasing. A news article by <a href=\"https:\/\/www.bbc.com\/news\/world-asia-india-61793884\" rel=\"nofollow\">BBC<\/a> highlights that air pollution is decreasing life expectancy by around 10 years.\u00a0In this blog, learn how the Delhi air quality index has changed over the past three years and learn about the government&#8217;s efforts to manage air pollution in the city.<\/p>\n\n<h2 class=\"wp-block-heading\" id=\"h-what-is-the-delhi-air-quality-index-aqi\"><span class=\"ez-toc-section\" id=\"What_is_the_Delhi_air_quality_index_AQI\"><\/span>What is the Delhi air quality index AQI?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n<p>The Air Quality Index is a scale to measure harmful pollutants in the environment to know the level. Particular matters 2.5 and 10 are the major pollutants taking several lives every year.\u00a0<\/p>\n\n<p>Delhi&#8217;s air quality index drastically deteriorates in the unhealthy, severe or hazardous category from October to February. In between Monsoon as from June to September, Delhi AQI remains in Good, moderate and satisfactory category. But every year, these five months break every previous record in air pollution levels. This is also known as winter pollution which gives a new name to Delhi every year such as Gas Chamber, Smog Capital, &#8220;Living Narak&#8221; (Hell) and many more.\u00a0<\/p>\n\n<h2 class=\"wp-block-heading has-large-font-size\" id=\"h-what-are-the-delhi-air-pollution-sources\"><span class=\"ez-toc-section\" id=\"What_are_the_Delhi_air_pollution_sources\"><\/span>What are the Delhi air pollution sources?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n<p>Many factors are responsible for affecting the air quality index of Delhi. Over 33 million people are residing in Delhi including a total registered vehicles of 19 million by 2021. It causes emissions from different sources. Several factors including road dust, vehicle emission, construction, open waste burning emission, stubble burning and many other factors result in air pollution in Delhi.

From late September to early February temperature drops below to 10\u02daC. Winter pollution affects the entire air pollution condition in Delhi. Low temperature traps more pollutants in the environment. Moreover, various activities take place during winter that lead to higher emissions. It is also known as <a href=\"https:\/\/www.aqi.in\/blog\/temperature-inversion-and-air-pollution\/\">thermal inversion <\/a>which results in <a href=\"\/?p=121095\">winter air pollution<\/a> in Delhi.\u00a0<\/p>\n\n<h3 class=\"wp-block-heading\" id=\"h-vehicle-emission\"><span class=\"ez-toc-section\" id=\"Vehicle_emission\"><\/span>Vehicle emission:<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n<p>Millions of vehicles on the road result in traffic congestion and more jams during peak hours of the day.
