Research Progress on Farmland Soil Heavy Metal Pollution and Remediation Technologies in the Yangtze River Basin

Abstract

Abstract Farmland pollution directly affects the economic benefits of crops and food security. In recent years, the condition of farmland soil in China is not optimistic, and its pollutants are mainly heavy metals. Soil is the basic condition for biological survival and the final melting and disintegration of pollutants. China’s soil pollution control work urgently, soil pollution control situation is more serious. In the process of economic transformation advocated by the state, pollution control should be strengthened, and soil ecological remediation technology should be vigorously studied and popularized, so as to effectively prevent soil pollution and meet the needs of sustainable development in China. This paper studies the research progress of heavy metal pollution and remediation technology in farmland soil in the Yangtze river basin, analyzes the current situation of farmland soil pollution in representative cities in the Yangtze river basin, and summarizes the main remediation methods of heavy metal pollutants, especially in farmland soil.
