The combination of unfavourable siting of industry and housing areas,
of the use of low grade coal and of stagnant meteorological conditions
is responsible for high pollutant concentrations in Cheng De. As this
city is famous for its Mountain Resort, an array of temples and palac
es of great historical value, assessment of air pollution and of the c
ontribution of different sources and the development of abatement meas
ures is necessary. Control schemes to prevent health problems and dama
ge to buildings are proposed.
