### Introduction
In recent days, parts of Delhi have been reported to have entered the ‘severe’ category of Air Quality Index (AQI), leading to widespread concern among residents and officials alike. Air pollution has become a critical issue in urban India, affecting millions and posing serious health risks. This article explores the causes behind the current smog crisis, its impact on health and daily life, and potential solutions to combat air pollution in the national capital.
### Understanding AQI and Its Health Implications
#### What is AQI?
The Air Quality Index (AQI) is a standardized way to communicate how polluted the air currently is or how polluted it is forecast to become. It measures pollutants like particulate matter (PM10 and PM2.5), ground-level ozone, carbon monoxide, sulfur dioxide, and nitrogen dioxide.
#### Health Risks Associated with Severe AQI Levels
When AQI levels reach a ‘severe’ rating, the health risks become substantial. Individuals with existing health conditions, children, the elderly, and even healthy adults can experience adverse effects. Symptoms may include:
– Respiratory issues
– Cardiovascular problems
– Increased asthma attacks
– Premature mortality for vulnerable populations
