An updated review on how biochar may possess potential in soil ARGs control on aspects of source, fate and elimination

Abstract

•	The sources, transmission routes and effects on human health of soil ARGs are summarized, and the mechanism of soil ARGs control by biochar is discussed on the basis of the positive effects by biochar.
•	The ways in which biochar affects soil ARGs are analyzed in several directions (soil physicochemical properties, heavy metal content, antibiotic content, microbial structure and enzyme activity) in an attempt to provide a basis for the next studies.
•	The mechanisms of biochar in the regulation of antibiotics and heavy metals for soil ARGs removal are systematically and comprehensively described, while also prospecting the potential application of biochar in soil ARGs removal.
