High PM2.5 linked to deaths: researchers
Researchers from Peking University say minute particle pollution as indicated by high PM2.5 readings will cause a spike in the mortality rate of patients suffering heart and lung diseases.
Because fine particles(PM2.5) is much smaller than inhalable coarse particles(PM10), its negative effects on human health is more severe.
When we breathe, the fine particles can reach the deepest regions of our lungs. And exposure to particles is linked to variety of significant health problems, ranging from aggravated asthma and one in this scale to pre-mature death in people with hard disease on the other. PM2.5 is worthy the name of "Invisible Killer".
