The apportionment of PM10 in Luojiaji industrial area ambient air of Nanchang city has been performed by academic designing
local samples collecting
laboratory analysis and model calculating etc.The samples of PM10 were collected at two sites:Nanchang iron&steel company of Environmental Monitoring Station
Luojiaji industrial area of He village.At the same time
the samples of five sources were collected
such as soil dust
coal smoke dust
steel dust
building material dust and traffic dust.Nine elements such as Ca
Mg
Al
As
Fe
Mn
Pb
S and Ti in both ambient and sources were measured by ICP-AES.On the basis of the Chemical Mass Balance(CMB) model for Nanchang city was developed.And the contribution rates of five sources to PM10 were got through model calculating:coal smoke dust was 32%
