摘要
To the Editor： In China and neighboring countries, there is increasing health concern over the dust storm fine particulate matter （PM） originating in the Gansu Corridor and Mongolian regions of China. PM is a mixture of various particles including crustal material, metals, and bioaerosols. Elevated levels of ambient PM were also reported to be associated with increased cardiopulmonary morbidity and mortality.A recent World Health Organization report indicated that exposure to fine PM air pollution and other pollutants caused approximately seven million deaths in 2012 worldwide, while the Global Burden of Disease Study showed that PM exposure was responsible for 2.9 million deaths and 69.7 million disability-adjusted life-years in 2013. Finally, studies showed that reduced PM concentrations were associated with reduced mortality risk.
