【 摘 要 】

As the core technology of soil heavy metal remediation and management in Tongguan gold mining area, only the objective and comprehensive evaluation of its governance effect can we promote this technology in Tongguan gold mining area and other similar areas Applications provide solid and reliable data support and scientific basis. In this study, samples were set up in the project area of Tongguan gold mining area. Primary data of the control area were obtained through sample collection and laboratory sample analysis. Soil samples of Tongguan gold mine project area were analyzed by single pollution index method and Nemero integrated pollution index The results showed that all kinds of metal elements in tillage soil have reached the level of cleanliness and the soil quality belongs to the first grade safety status, which provides the data support and scientific basis for the popularization and application of the project.
