Abstract
Description
technical field
[0001] The invention belongs to the technical field of environmental protection, and relates to a pollution ecological restoration technology, in particular to a method for phytoremediation of arsenic-contaminated soil. Background technique
[0002] Due to geological causes or industrial production activities such as arsenic mining, smelting and processing, a large area of arsenic-contaminated soil is produced. Arsenic pollution not only leads to a decrease in crop yields, but also results in farmland abandonment in severe cases, and the arsenic in the soil may enter the human body through the food chain or water bodies, thereby endangering the health of livestock and residents, and even causing vicious events such as poisoning of residents. In areas with severe arsenic pollution (high arsenic areas), due to the difficulty in plant growth, the natural landscape and ecological balance have been damaged to varying degrees, and some villages have been deserted...
