- Abstract:
-
The pollution levels of heavy metals and the relations between they and irrigation types was studied in top soils of different irrigation types in Xi’an City.The results showed that the contents of heavy metals have great differences in the soils of different irrigated types.The maximum average contents of Cu, Zn, Cd, Pb were found in Fenghui Channel area, the medium ones were found in Dengjiacun area, the ones in Zaohe irrigated area and well irrigated area were lower, and the minimum ones were in Jinghui Channel area.Dengjiacun wastewater irrigated area had the highest contents of Ni and Cr.Fenghui Channel area, Zaohe irrigated area, well irrigated area and Jinghui Channel area gradually decline.The pollution indices of different irrigated areas was the order of Fenghui Channel>Dengjiacun wastewater irrigated area>well irrigated area>Zaohe irrigated area>Jinghui Channel area.The heavy metals in Fenghui Channel area, Dengjiacun wastewater irrigated area and Zaohe irrigated area root in wastewater.The soot from Baqiao Heat-electric works and Weihe electric works and the applications of farmhouse fertilizer were an important input of heavy metals in well irrigated area.The original materials in Jinghui Channel area primarily affected the contents of heavy metal.
