[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.
