Air pollution causing heart diseases

AIR pollution poses as much health hazard as tobacco smoking, according to a paper published in Cancer Biology & Medicine (Zhao, 2019). Fine particles floating in the air, known as PM2.5, present the greatest threat to human health among the air pollutants. These microscopic particles are ten times finer than the thickness of our hair. While breathing in polluted air, PM2.5 quickly reaches our lungs and blood circulation and remains there for a long time.
