Agree, but as you stated "primary", it's not the only reason.
China loves its coal burning plants, spewing out lots of particulate pollutants, that can be sucessfully filtered by surgical masks.
Surgical masks wouldn't do a very good job filtering out the gaseous components of photochemical smog (nitrogen oxides, sulphur oxides, ground-level ozone, and volatile organic compounds like hydrocarbons), but could do a pretty good job filtering out smoke particulates in photochemical smog
