Though antitheses experiments

the content of three types mine areas wastelands(graphite gangue

the cinder pile of power house and stone pit)heavy metals

Zn

Pb

Ni

Cr

Hg

As of the soil were determined and analyzed in the area in Jixi city.The result is showed as follows: the content of Zn and Ni in graphite gangue and Ni in the cinder pile of power house all exceed B environmental quality standard for soils;the content of other three heavy metals Cr

As and Pb all don't exceed B standard.The other content of heavy metals is all under the A environmental quality standard for soils

except Zn and Cr in the cinder pile of power house

the content of Hg in these mine areas wastelands all exceed C standard

indicates that the heavy metals Hg is the primary and the most strongest fountainhead of pollution.The comprehensive pollution index in graphite gangue

the cinder pile of power house and stone pit is 5.60

3.74 and 7.66

the pollution in these area is in heavy grade.That result indicates that these three wastelands are the strong pollution resource

they may bring strong intimidation and pollution to the environment around these area.
