Air pollution in Indian cities raises death risk across age groups: Study

In Indian districts, air pollution exceeding national standards have been shown to increase death risk across all age groups -- by 86 per cent in newborns, 100-120 per cent in children under five years of age and 13 per cent in adults, according to a study.

A team of researchers, including those at the International Institute for Population Sciences, Mumbai, looked at fine particulate matter (PM2.5) pollution levels across over 700 districts. Data for analysis was taken from the National Family and Health Survey (fifth round) and the National Ambient Air Quality Standard (NAAQS).

In households not having a separate kitchen, the study found higher chances of deaths among newborns and adults.

Among newborns and children aged under five, the chances "appeared to be almost two-fold and more than two-fold higher, respectively, in the districts of India where the PM2.5 concentration is up to the NAAQS level," the authors said in the study published in the journal GeoHealth.
