Bangalore: South Indian cities are regarded to have better air quality and pollution levels than their northern equivalents, however this may no longer be the case. According to a study conducted by Greenpeace India, some cities in the states of Andhra Pradesh, Telangana, Tamil Nadu, Karnataka, and Puducherry have pollution levels that surpass WHO recommendations.
Greenpeace India's recent analysis, which looked at data from the Central Pollution Control Board (CPCB) from ten major cities in southern India, found that average pollution levels substantially exceeded the latest WHO limits.
Based on the availability of data, population, and monitoring station networks, data from the Central Pollution Control Board (CPCB) was selected and analyzed for 10 cities: Bengaluru, Hyderabad, Chennai, Amaravati, Visakhapatnam, Kochi, Mangalore, Puducherry, Coimbatore, and Mysore. The annual average readings of PM2.5 and PM10 exceeded WHO's revised limits by many times, notwithstanding pandemic-induced lockdowns and subsequent reductions in economic operations, according to a statement released by Greenpeace India on Thursday.
Annual PM2.5 levels in Coimbatore, Bengaluru, Mangalore, and Amaravati exceeded WHO limits of 5 Aug/m3 by 6 to 7 times. PM2.5 levels in Mysuru, Kochi, Chennai, and Pondicherry were 4 to 5 times higher than the limits.
