Non-exhaust emissions tend to contain mostly PM10, but a signifi-cant proportion of the emissions contains fine PM2.5 as well. The chemical characteristics of non-exhaust PM emissions vary per source, but are mainly made up of heavy metals such as zinc (Zn), copper (Cu), iron (Fe) and lead (Pb), among others (Thorpe and Harrison, 2008).

From 1990 to 1995, PM emissions increased rapidly, driven by the growth of cement production. The decline of PM emissions after 1996 was due to the implementation of the new emission standards for the cement industry issued in 1996 (GB4915-1996; Table S1) and the slowing down of the economy during the Asian financial crisis.

Mechanical collection devices (i.e. cyclones and dry filters) are effective, low cost ways to control PM emissions from processing equipment. Unfortunately, higher collection efficiency in any type of equipment can often mean higher costs. For example, a baghouse can be a very high efficiency control option but is more expensive than the others.
