Toxic air does not know borders. A simulation study has gauged that 80 percent of the total untimely deaths in India due to outdoor air pollution is caused by emissions within the country itself, while pollutants blowing into India from outside also made a substantial contribution to the early loss of lives.

Within India, home to 14 of the world’s most polluted cities, emissions in the densely populated Indo Gangetic Plain (IGP) are responsible for nearly half (46 percent) of the premature deaths in the country linked to PM2.5, according to an estimate by researchers at Colorado State University.

“And the anthropogenic emission in IGP not only hits the population in IGP, that extends from the foothills of Himalayas to the eastern plateau, but close to 20 percent of the impact of IGP emissions is outside of this region,” said study author Liji M. David. Read More
