As you might imagine, in our modern, de-industrialized cities, air pollution is not as much from industry as it once was, but is much more from cars. This is especially true near highways and heavily used arteries.
Air pollution from cars, seemingly combustion products and grit, comes in many forms. The sort described in this article is probably 2.5 micron or larger in size and mostly affect respiratory health.
Another key type of pollutant is defined as Ultra Fine Particulate. These are also combustion products, but they have less effect on respiratory health but much greater effect on cardiovascular health. The other key quality of ultra fine particulates is that the concentrations are much higher the closer you get to a highway. Because of this quality, changing air management in buildings near to highways, and generally avoiding building near highways, are important for avoiding serious adverse health effects. You always figured it was true.... now the evidence is pretty strong.
