Kolkata records highest stroke deaths due to PM2.5 exposure: Study

Hale-and-hearty youngsters suddenly collapsing and dying of stroke is not an unheard-of phenomenon in the city. A study by IIT-Kanpur has attributed the exposure to PM2.5 in the air to the high premature mortality rate in Kolkata, a reason that had remained mostly unexplained so far. In fact, stroke death rate due to PM2.5 exposure in a city was the highest in Kolkata, revealed the study, which surveyed million-plus population in 29 cities in India.
