The situation needs to be defined more specifically. Also, besides just knowing the quantity of particulates produced, it is important to known the composition of the particulates (lead, phosphor, glass, etc) and their size distribution - PM2.5 is much more important in its health aspects than PM10, which in turn is more important than larger sizes.
