Delhi is always in talks for its poor air quality, there have been various studies done to find out what exactly is the cause of the air quality going downhill with every passing year.
In a recent study led by scientists from the Indian Institute of Technology, Tirupati has concluded that people's health was impacted severely when exposed to extreme temperatures in Delhi and high pollution levels.
The study, titled ‘'Health impact assessment of Delhi's outdoor workers exposed to air pollution and extreme weather events: an integrated epidemiology approach' assessed the workers for breathing difficulties or acute lung function impairment; irregular heartbeats & chest discomfort; back, shoulder, and joint pains; redness of eyes and irritation, and finally, skin rashes, headaches & overall weakness, both in winters and summers. It is published in Springer's Environment Science and Pollution Research.
The study revealed that those working outdoors for long periods in Delhi complained of health complications, including breathing difficulties or acute lung function impairment, irregular heartbeat and chest discomfort, back, shoulder, and joint pains, eye redness and irritation, skin rashes, headaches, and overall weakness, as per Hindustan Times report.
In another study by the Indian Institute of Technology (IIT) Delhi, titled, ‘Chemical speciation and source apportionment of ambient PM2.5 in New Delhi before, during, and after the Diwali fireworks.’
“Both stubble burning and increased heating requirements of the region in winters drive the biomass burning activity,” said Professor at IIT Delhi and one of the investigators of the research Vikram Singh. The conclusion of the study was that biomass contributed to the poor air quality of Delhi and not the firecrackers post-Diwali
