Guwahati, March 19: Guwahati, the vibrant capital city of Assam, has unfortunately earned a dubious distinction. According to the 2023 World Air Quality Report by IQAir, a Swiss air quality monitoring body, Guwahati is now the second most polluted city in the world. This alarming ranking highlights the city’s deteriorating air quality and the urgent need for action.
The Report’s Stark Findings
The report paints a concerning picture. Guwahati recorded an average annual PM2.5 concentration of 105.4 micrograms per cubic meter. PM2.5 refers to fine particulate matter, tiny particles that lodge deep within our lungs and pose significant health risks. The World Health Organization’s (WHO) recommended safe limit for PM2.5 is just 10 micrograms per cubic meter. Guwahati’s air is thus over ten times more polluted than what is considered safe.
Several factors contribute to Guwahati’s worsening air quality:
Construction Boom: The city’s rapid development has led to a surge in construction activities. This generates dust pollution, significantly impacting air quality.
Vehicular Emissions: Guwahati’s growing population has resulted in a rise in vehicles on the road. Traffic congestion and exhaust fumes are major contributors to air pollution.
Industrial Activity: While not as prominent as in other Indian cities, industrial activity in and around Guwahati also adds to the pollution burden.
India’s Troubled Air
Guwahati’s plight is not unique. The IQAir report also ranked India as the third most polluted country globally in 2023, with a worrying jump from its eighth position in 2022. Nine out of the ten most polluted cities in the world are now in India, highlighting the severity of the air pollution crisis facing the nation.
Health Impacts of Pollution
Exposure to high levels of PM2.5 can lead to a range of health problems, including respiratory illnesses, heart disease, stroke, and lung cancer. Children, the elderly, and those with pre-existing health conditions are particularly vulnerable.
Guwahati’s ranking as the second most polluted city is a wake-up call. By implementing effective solutions and fostering community engagement, Guwahati can work towards cleaner air and a healthier future for its residents.
