Application of siegesbeckia herb in remediation of soil contaminated with heavy metal cadmium

Abstract

The invention discloses application of feverfew siegesbeckia herb in remediation of soil contaminated with the heavy metal cadmium, which is realized through planting siegesbeckia herb in soil contaminated with the heavy metal cadmium. The siegesbeckia herb has an excellent property of accumulating the heavy metal cadmium, can absorb and accumulate the heavy metal cadmium, and transfer most of the heavy metal cadmium above the ground in order to realize remediation of soil contaminated with the heavy metal cadmium through being planted in the soil. The invention not only has the characteristics of low cost and strong operability because the siegesbeckia herb needs no special treatment during the growing process but also can increase the remediation effect of heavy metal in soil of unit area because the siegesbeckia herb has a large quantity, and develops a new plant resource applied for plant remediation of soil contaminated with heavy metal.

Description

technical field [0001] The invention relates to the technical field of remediation of heavy metal pollution in the environment, in particular to the application of a plant scutellaria in remediation of heavy metal cadmium pollution in soil. Background technique [0002] The heavy metal cadmium (Cd) pollution in the environment has the characteristics of concealment, long-term and irreversibility. Its pollutants have poor mobility in the medium, long residence time, cannot be degraded by microorganisms, and can be transmitted through the food chain, which will eventually affect human health. have an immeasurable impact. The Japanese bone disease incident that shocked the world was caused by the pollution of cadmium in the soil. Therefore, cadmium-contaminated soil urgently needs to be treated. [0003] Phytoremediation using heavy metal-enriched plants or hyperaccumulators is one of the research hotspots in environmental science today. It has many characteristics such as lo...

AI Technical Summary

Problems solved by technology

Therefore, the purpose of the present invention is to provide a new application of a new plant variety, Scutellaria chinensis, in remediating heavy metal cadmium pollution in soil for the above-mentioned problem of insufficient plant variety resources that can be used for bioremediation of heavy metal pollution in soil.
