An article in the International Journal of Epidemiology reported that the fine particles in polluted air are linked to an increased risk of cardiovascular death, even at levels below current international standards.

“The remarkable thing about this work is that the authors analysed information from over 500,000 adults representing more than 7 million ‘person-years’ and found that the risk of death depended on the amount of fine particles inhaled,” said Dean Schraufnagel, MD, Director of the Forum of International Respiratory Societies (FIRS) and member of FIRS Environmental Committee.

The study evaluated data from the detailed health and diet survey conducted by the National Institutes of Health (NIH) and the American Association of Retired Persons (AARP). The study volunteers, aged between 50 and 71, were followed for 10 years.
