After how many years of spraying, why has there been no in flight sampling of suspect aircraft plumes? - Specifically looking for these chemicals, polymers, and metal oxides. (No reason why this could not be done (professionally), even in violation of FAA regs.)

Unfortunately, it is in German. And he says also that they are all afraid of loosing their jobs - even breathing themselves that stuff:
