Air pollution kill more than 3.2million people yearly.. More than AIDS and Malaria combined

Do you know that air pollution kill more than 3.2million people yearly? That is, more than AIDS and Malaria combined. Now that our Government attention is on rebuilding our local refineries. Should be worried?
Scientists say meeting global air quality guidelines could prevent 2.1 million deaths per year.

They developed a global model of how changes in outdoor air pollution could reduce health problems, including heart attack, stroke and lung cancer.

The research was published in the journal Environmental Science and Technology.
And their research reveal that particulate air pollution results in 3.2 million premature deaths each year – more than the combined impact of HIV/AIDS and malaria.
By meeting the World Health Organisation’s (WHO) particulate air quality guidelines, the team estimated that 2.1 million early deaths could be prevented.
The new study is the first detailed analysis of how improvements in particulate air pollution worldwide would yield improvement in health, and where those improvements would occur.
Outdoor air pollution are from particulate matter (PM) smaller than 2.5 microns, which can enter deep into the lungs.
Breathing PM is associated with increased risk of heart attack, stroke and other cardiovascular disease; respiratory illnesses such as emphysema; and cancer.
PM pollution comes from fires, coal power plants, cars and lorries, plus agricultural and industrial emissions.
