This paper investigates the mechanism of biochar as capping material on PAHs removal in river sediments. When biochar was amended, pyrene was decreased through strengthened aging effects, which was attributed to high adsorption capacity of the biochar. While biochar did not alter the main microbial community, it provided a stable niche for PAHs degradation microorganisms, attributed to the porosity and biological affinity of biochar. According to the results, biochar increased the opportunity for PAH-degraders to contact PAHs in sediments. When electron acceptors were available, the pyrene-degraders in biochar pores degraded the adsorbed pyrene rapidly. https://iopscience.iop.org/article/10.1088/1755-1315/281/1/012016/pdf.
