Abstract: Based on the data from the soil geochemical survey, heavy metal anomaly, such as As, Bi, Cd, Cu, F, Ni, Sb, Hg, and Zn, were found in farmland soils in the north of Jiyang County. The heavy metal anomaly exhibited the features of bigger anomalous contrast and lower concentration coefficients. The anomaly verification results indicated that the anomalous heavy metal element contents have remarkable correlation with major elements of SiO₂, Al₂O₃, Fe₂O₃, showing the negative correlation with SiO₂ and positive correlation with Al₂O₃ and Fe₂O₃. The phenomenon indicated that the major components of soil and soil texture were the main factors causing anomalies, and the human activity was the secondary ones. The wheat and cucumber samples from the anomaly area were contaminated by Hg and F in different levels, which indicated that toxic elements had influenced the farm product quality and the attention should be paid. The author considered that scientific and adequate fertilization, strengthening the control of various pollution sources, continuing to maintain the soil alkalinity environment were the effective measures for preventing human health from the heavy metal pollution harms in heavy metal anomaly area.
