Advances in Bioremediation of Agricultural Soil Contamination

Abstract

With the rapid advancement of industrialization and agricultural intensification, the issue of farmland pollution has garnered significant attention. This paper introduces the sources and hazards of farmland pollution, along with the types, principles, and technical advantages of bioremediation. Additionally, it makes a brief prediction of future farmland restoration efforts. Research indicates that the primary sources of farmland pollution currently include four factors: the natural environment, atmospheric deposition, irrigation water, and agricultural production activities. There are two primary methods of remediation for farmland contamination: phytoremediation and microbial remediation. Phytoremediation is mainly used in heavy metal pollution treatment and can be divided into hyper-accumulation plants and low-accumulation crops based on the remediation method. Microbial remediation, meanwhile, is primarily utilized to remediate organic pollution and assist phytoremediation.
