Biochar technology provides a potential approach to mitigate soil pollution in agricultural
production. However, limited studies have focused on the effects of different kinds of biochar
on polycyclic aromatic hydrocarbons (PAHs) bioaccumulation. To address this issue, three
kinds of biochar including wheat straw biochar (WBC), sludge biochar (SBC) and pig
manure biochar (PBC) were prepared through the technology of oxygen limited pyrolysis,
and a spot experiment was conducted to assess the mitigation effects of three kinds of …
