Heatwaves Worsen Andhra Air Quality
19 Jul
Summary
- Heatwaves increase surface ozone levels in Andhra Pradesh.
- Ozone levels rise 14% to 25% above WHO guidelines during heatwaves.
- Compound threat of heat and pollution risks respiratory illnesses.
Heatwaves gripping Andhra Pradesh are not only raising temperatures but are also degrading air quality by elevating surface ozone levels. Research from IIT Kharagpur indicates that the East Coast region experiences a marked increase in ground-level ozone during heatwave periods.
Prolonged heat spells disrupt sea-breeze circulation, trapping pollutants and intensifying ozone formation under strong sunlight. Ozone levels have been observed to exceed World Health Organization guidelines by 14% to 25% during these events. This poses a significant threat, especially to coastal urban areas like Visakhapatnam and Vijayawada.
The study warns that this escalating trend, fueled by rising temperatures and industrial emissions, could lead to an increase in respiratory and cardiovascular diseases. Vulnerable populations, including children and the elderly, are at greater risk. Integrated policies addressing both climate change and air pollution are crucial as these compound events become more frequent.
