Most polluted countries

This chart from WHO shows China well down the list.  Does it mean something that the five worst offenders are Islamic?  And what does PM2.5 mean?  This is a catchall definition of pollution that includes all particulate matter under  2.5 micrometers in size.  That means four hundred specks would make a row less than one millimeter long.  This is stuff that you breathe in and out and can float for ages in the breeze.  H/T  Zero Hedge.
