Characteristics of Antibiotic Contamination of Soil in China in Past Fifteen Years and the Bioremediation Technology: A Review

In recent years, the contamination of antibiotics and their resistance genes (ARGs) has attracted the extensive attention of researchers at home and abroad. Soil is an important sink for the migration and transformation of antibiotics and ARGs, which pose a threat to soil organisms and human health. According to the relevant investigations in the past 15 years, the soil has been polluted by antibiotics to varying degrees in China. Bioremediation is a green and environment-friendly remediation technology, which has great potential in the remediation of antibiotic-contaminated soil. This review summarized the spatial and temporal characteristics of antibiotic pollution of soils in China in the past 15 years and the application of plants, animals, and microorganisms in the remediation of antibiotic-contaminated soil. In particular, the recent research advances of microbial electrochemical systems in removing antibiotics and ARGs in soil were reviewed, and the unaddressed issues of relevant research and the direction of future development were proposed, in order to provide a scientific basis for soil pollution remediation.
