A method for inferring a limit value of available content of heavy metals in soil
By collecting samples of agricultural products and root soil, and using the Burr III distribution function and agricultural product quality standards, the limits of available heavy metal content in soil were estimated. This solved the problem of the lack of standards in existing technologies, and enabled effective evaluation of stabilization technologies and safe management of agricultural products.

AI Technical Summary
The lack of standards for the available content of heavy metals in soil in existing technologies makes it impossible to effectively evaluate the remediation effects of stabilization technologies and the safety management of agricultural products.
By collecting soil samples of agricultural products and their root systems, the content of heavy metals was determined. The limits of available heavy metal content in the soil were estimated using the Burr III distribution function and agricultural product quality standards. The available heavy metal content was determined by CaCl2, DTPA, or gradient diffusion thin film extraction methods.
A method for estimating the limits of available heavy metal content in soil is provided, which can evaluate the remediation effect of stabilization technology and ensure the safety of agricultural products, simplifying the operation and improving the feasibility of data processing.
