Ironic that the article associates particulates with cars when,

It would be interesting to see what the quality of air in a city street and
inside your average hut/house anytime from the neolithic to the 1950s before
the clean air act. I suspect today we're breathing cleaner air than anyone has

heated by a wood or coal burning hearth and lit by candles.
