摘要：

As and Cd pollution in sediment has posed a potential threat to ecosystem owing to their high toxicity. Fixing heavy metals and transforming their speciation into stable forms can be a sustainable method. In this study, nine biomass feedstocks were pyrolyzed into biochars for immobilization of As and Cd in sediment, and the accompanied changes in the microbial community were analyzed to evaluate their effect on bioavailability. The heavy metal immobilization capacity of biochars in sediment were assessed by measuring the change of As and Cd con...
