A woman wearing a mask walk through a street covered by dense smog in Harbin, northern China, Monday, Oct. 21, 2013. Visibility shrank to less than half a football field and small-particle pollution soared to a record 40 times higher than an international safety standard in one northern Chinese city as the region entered its high-smog season.
