Rich, the recent research on fine particulates points to PM3 as being a real

Well, I don't think so. The building is built in '93 and no
modifications on the filtering system has been made after that. And just
by looking at specific surfaces next to the window is enough to prove
that. Even after a week these are coated with a thin black layer of soot.

We as people living next to the street have started to start a trial
against to local municipal to see if we can get levels down but it is
really worrysome!
