What are Particulate Emissions? (with pictures)

Sometimes, particulate emissions are visible in the form of soot or smoke, because the particles are so large. Most are not visible, however, which is part of what makes them dangerous, because people do not realize that the emissions are occurring. Small particles are also more dangerous because they are less likely to be trapped in the mucus linings of the nose and throat.
