Air quality plummets across Himachal Pradesh as Diwali night nears

As the festive season approaches, Himachal Pradesh’s air quality is showing signs of significant decline, with the Air Quality Index (AQI) levels in multiple cities crossing concerning thresholds. Data from the State Pollution Control Board reveals that AQI in five cities, including Baddi, Una, and Paonta Sahib, has surpassed 100 micrograms, with Baddi recording the highest levels at 177 micrograms. Just days prior, on October 25, Baddi’s AQI had spiked to 233 micrograms while the AQI in other cities remained under 100, indicating a rapid deterioration.

This seasonal surge in pollution levels is largely attributed to dust and stubble burning in neighboring states like Punjab and Haryana, alongside increased local vehicle emissions in Himachal’s dry, rainless conditions. In the past month, the lack of precipitation has led to elevated dust levels, further impacting air quality across the region. With Diwali just around the corner, the additional emissions from firecrackers are expected to worsen the AQI.

Significant rises have been recorded in traditionally clean areas. In Shimla, AQI levels jumped from 32 to 52 micrograms over the past two days, while Manali saw an increase from 28 to 89 micrograms. Dharamshala, too, witnessed an AQI rise from 45 to 67 micrograms. These hikes mark a concerning trend in a state known for its clean air and lush landscapes, with five cities in the “Carbon Credit State” breaching the 100 microgram mark.

While industrial areas like Baddi are particularly vulnerable to pollution, prolonged industrial closures due to Diwali might temporarily ease emissions. However, officials warn that the continued stubble burning in the region may still influence air quality.

Public health experts caution that prolonged exposure to poor air quality increases the risk of respiratory conditions, including asthma, and can cause skin irritation and eye discomfort. As Himachal’s skies grow hazier with light smog layers, the state’s clean-air reputation is at risk, making preventive measures imperative for both residents and local authorities to protect public health.
