Patna: Though winter has yet to begin in Bihar, air pollution has already reached hazardous levels. Pollution is increasing throughout Bihar and nearby areas, with the Air Quality Index (AQI) in parts of Patna reaching alarming levels well before the Diwali season. Traditionally, pollution spikes after Diwali, but this year, the AQI has worsened prematurely, causing health issues such as difficulty breathing and eye irritation for many residents.
In Patna, air pollution levels continue to climb as temperatures drop. AQI readings have surpassed 170 at key locations like Dak Bungalow Square and the Planetarium, while Raja Bazaar recorded an AQI of 165. The anticipated use of firecrackers during Diwali could lead to an additional surge in AQI, potentially worsening air quality further.
One of the primary contributors to the deteriorating AQI is an increase in dust particles, with PM10 particle levels in Patna currently double the standard limit. Dr Sunil Kumar Singh, an ophthalmologist, warns that those with asthma and other respiratory conditions should exercise caution, suggesting they wear masks when outdoors. He also advises residents to wash their eyes with water upon returning home to relieve discomfort caused by the polluted air.
The AQI categorises air quality into six levels: ‘good’ (0-50), ‘satisfactory’ (51-100), ‘moderate’ (101-200), ‘poor’ (201-300), ‘very poor’ (301-400), and ‘severe’ (401-500). With Patna’s AQI now reaching levels categorised as ‘moderate’ and approaching ‘poor’, health risks are significant, especially for vulnerable individuals with pre-existing conditions.
