Air pollution kills

 

Air pollution is a killer. A new study shows how much of a killer it is in the country of India.

Air Pollution in India Linked to Millions of Deaths

"Air pollution consisting of particles smaller than 2.5 micrometers in diameter, PM2.5, can enter the lungs and bloodstream and is a major health risk in India. Researchers have now examined the link between these particles and mortality over a ten-year period. The study is based on data from 655 districts in India between 2009 and 2019.

“We found that every 10 microgram per cubic meter increase in PM2.5 concentration led to an 8.6 percent increase in mortality,” says Petter Ljungman, last author and researcher at the Institute of Environmental Medicine at Karolinska Institutet.

The research analyzed the relationship between changes in air pollution levels and mortality. The results show that around 3.8 million deaths over the period can be linked to air pollution levels above India's own air quality guidelines of 40 micrograms per cubic meter."
