摘要
The concentration of heavy metals was investigated in black soil samples collected from the fields treated with chemical in Bayan County which were from the vegetation covers,bare soil and grain fields without any chemical treatments in Hailun National Field Research Station of Agroecosystem,Chinese Academy of Sciences (CAS) in July,2009.Results showed that the presence of significantly high concentration of zinc (Zn) and lead (Pb) in soils covered with grass vegetation.However,mercury (Hg),copper (Cu),nickel (Ni),cadmium (Cd),and arsenic (As) were found within the permissible limit set by international environmental agencies.
