Air quality in several major cities of Karnataka has shown a concerning dip, with Bengaluru recording poor air levels, even as coastal and southern districts continue to enjoy clean and healthy air.
According to recent data, Bengaluru’s Air Quality Index (AQI) has ranged between 140 and 175, placing parts of the city in the poor to unhealthy category. Localities such as Hebbal, Silk Board Junction and BTM Layout reported AQI readings touching 158.
Experts from the Central Pollution Control Board attribute the decline to heavy traffic congestion, road dust and misty weather conditions that trap pollutants closer to the ground.
Health advisory issued
Health officials have urged vulnerable groups — including children, senior citizens and individuals with respiratory ailments — to wear masks and limit outdoor exposure. People with asthma, allergies or breathing difficulties are advised to exercise caution, particularly during peak traffic hours.
Authorities have also encouraged citizens to avoid prolonged outdoor activities until conditions improve.
Coastal and southern districts fare better
In contrast, cities such as Mysuru, Mangaluru, Udupi and Chamarajanagar continue to record AQI levels in the “good” category, making them suitable for outdoor activities and exercise.
Understanding AQI levels:
- Good: 0–50
- Moderate: 50–100
- Poor: 100–150
- Unhealthy: 150–200
- Severe: 200–300
- Hazardous: 300–500+
Environmental experts emphasise that sustained urban planning, better public transport usage and dust control measures are essential to improve air quality in Bengaluru.
