FILE - In this Oct. 19, 2014, file photo, a runner, wearing a mask to protect herself from pollutants, looks at her smartphone as she and others jog past Chang'an Avenue near Tiananmen Square shrouded in haze at the start of 2014 Beijing International Marathon in Beijing. Seven years after the 2008 Beijing Olympics sparked talk of a dramatic clean-up of pollution in Beijing, a milky haze still covers the city on most days and is expected to be there when the IAAF World Championships marathons take place - Aug. 29, 2015 for the men, and Aug. 30, 2015 for the women. According to a recent study, 1.6 million people die each year in China from heart, lung and stroke-related problems due to polluted air. (AP Photo/Andy Wong, File)
