Pollution Characteristics and Assessment of Heavy Metal in Different Land-use Types in Tianjin City
[Objective] The heavy metal pollution status and pollution sources in soil of Tianjin City was studied in order to provide a theoretical basis for preventing soil heavy metal pollution.[Methods] A total of 146 samples were collected from the industrial areas
farmland
water sources
livestock farm and vegetable bases in Tianjin City. The pollution characteristics of heavy metals
mainly refering to the heavy metal content in soils of different land-use types
was evaluated by single factor pollution index and Nemero comprehensive pollution index method
and the sources of heavy metals were also discussed.[Results] The results showed that different heavy metals were all found accumulated in soils
but the overall pollution level in Tianjin City was lower. The over standard rates of Pb
Ag and Cd were 84.25%
76.71% and 68.49%
respectively. And land-use types affected the accumulation degree and categories of heavy metals. The vegetable base had the highest accumulations of total heavy metal among 5 land-use types
mainly including Cd
Hg
As
Cr
Cu
Ni
V
Mn
Co and Ag. The industrial area had the highest Zn concentration
while the Pb concentration was higher in the farmland
and livestock and poultry farmland.[Conclusion] In an overall
the level of soil pollution in Tianjin City is relatively low. However
in terms of land-use types
the pollution levels of Pb and Zn in the industrial areas
farmland and livestock farms were higher
wherein it should be paid more attention to in the process of land use and management.
