Introduction
Noida, a rapidly growing city in India, faces significant air pollution challenges. Understanding the Noida Air Quality Index (NAQI) is crucial for residents to make informed decisions about their health and well-being. This guide provides a comprehensive overview of the NAQI, its implications, and practical steps you can take to mitigate its adverse effects.
Understanding the NAQI
The NAQI is a measure of air quality based on the concentration of five major pollutants: particulate matter (PM10 and PM2.5), sulfur dioxide (SO2), nitrogen dioxide (NO2), and ozone (O3). Each pollutant is assigned a sub-index based on its concentration, and the overall NAQI is calculated as the maximum of these sub-indices.
The NAQI is classified into six categories with corresponding health implications:
Category | NAQI Range | Health Implications |
---|---|---|
Good | 0-50 | Minimal health impact, suitable for outdoor activities |
Satisfactory | 51-100 | Mild health effects on sensitive individuals |
Moderate | 101-200 | Moderate health effects on most people |
Poor | 201-300 | Compromised respiratory health, increased risk of heart disease |
Very Poor | 301-400 | Severely compromised respiratory health, increased risk of asthma attacks and cardiovascular issues |
Severe | 401+ | Extreme health risks, life-threatening conditions |
Current Air Quality in Noida
According to the Central Pollution Control Board (CPCB), the average NAQI in Noida for the year 2022 was 293, indicating poor air quality.
Pollutant | Concentration | Unit |
---|---|---|
PM10 | 226 | µg/m³ |
PM2.5 | 148 | µg/m³ |
SO2 | 16 | µg/m³ |
NO2 | 58 | µg/m³ |
O3 | 51 | µg/m³ |
