Pollution Levels Peak Across North India Two Days Ahead Of Diwali | Check Full List - News18

Recent data from the Central Pollution Control Board shows that the concentration of fine particulate matter (PM2.5) has surged in major North Indian cities such as Delhi, Lucknow, and Kanpur, reaching values well above the permissible threshold of 60 micrograms per cubic metre. The spike was observed on the morning of October 28, with readings indicating a rapid increase compared with the previous week. Experts attribute the rise to a combination of factors, including the burning of agricultural residue in neighboring states, heightened vehicular traffic, and stagnant atmospheric conditions that trap pollutants close to the ground.

The timing of the pollution peak is especially concerning because Diwali celebrations traditionally involve the lighting of firecrackers, which release additional toxic substances into the air. Health officials have warned that exposure to high levels of PM2.5 can aggravate respiratory illnesses, cause eye irritation, and increase the risk of cardiovascular events, particularly for vulnerable groups such as children, the elderly, and those with pre‑existing conditions. In response, several municipal corporations have announced temporary bans on the sale of certain firecracker types and have increased patrolling to enforce existing restrictions.

For residents of North India, the situation underscores the importance of taking preventive measures during the festival period. Authorities recommend staying indoors during peak pollution hours, using air purifiers where possible, and wearing masks that meet N95 standards when venturing outside. The government is also expected to issue advisories on the safe conduct of Diwali celebrations, balancing cultural traditions with public health considerations. Continued monitoring will determine whether the pollution levels subside after the festival or remain elevated due to lingering emissions.
