Safe utilization and zoning on natural selenium-rich land resources: a case study of the typical area in Enshi County, China.

Selenium (Se) is an essential trace element. However, Se in soil is often accompanied by heavy metals, such as cadmium (Cd), because of geological background. The safe utilization of such Se-rich land resources remains a challenge.

[Land Safety Zoning Method in High-Selenium and High-Cadmium Areas].

The selenium in the soil of Enshi, Hubei Province, is very rich, but there is also a certain degree of cadmium pollution risk.
