Abstract Base on the mathematical model of delayed geochemical hazard (DGH), the DGH characteristics of Pb element in the soil of Daxing Town, Anhui Province is studied. The result shows that the Pb element in the soil of Daxing is releases in the trend of TRCPPb→PbE+C. About 11% of soil area in Daxing has the possibility to break out DGH of Pb element, because the Daxing Town is an important industry town of Anhui Province. The study on DGH is of great significance for early-warning of the hazard of heavy metal elements in soil.
