Phosphorus (P)-modified biochar can efficiently remediate cadmium (Cd)-contaminated soil. However, the mechanisms of responses of alkaline phosphatase (ALP) and phoD-harboring microorganisms, which are notably sensitive to Cd and P, are not clear during the remediation process. In this study, apple (Malus domestica) tree branches were co-pyrolyzed with tripotassium phosphate (KPO) to prepare P-modified biochar, which was used to remediate Cd-soil contaminated soil collected near a mine site.

Biochar application for the remediation of cadmium (Cd)-contaminated soils may result in a relative deficiency of phosphorus (P) due to the disruption of soil nutrient balance. However, the P acquisition strategies of plants in such situation are still unclear. In this study, analyses on soil zymography and root morphology were combined for the first time to investigate the effects of pristine and P-modified biochars from apple tree branches on the P acquisition strategies of wheat under Cd stress.

Phosphate (P)-modified biochar is a good material for cadmium (Cd) immobilization, and the pore-forming effect of potassium ions (K) can favor the P loading on biochar. However, few studies have been done specifically on Cd(II) removal by composites of potassium phosphates with biochar, and the removal potential and mechanisms are not clear. Herein, apple tree branches, a major agricultural waste suitable for the development of porous materials, were pyrolyzed individually or together with KHPO, KHPO·3HO, or KPO·3HO to obtain biochars to remove Cd(II), denoted as pristine BC, BC-1, BC-2, and BC-3, respectively.

Article Synopsis
  • The study analyzed the concentrations of PCDD/Fs, PCBs, and PCNs in soil near a secondary copper smelter, finding significant contamination, particularly within 300 meters of the facility.
  • It was observed that as distance from the smelter increased, the levels of these pollutants decreased exponentially, with historical use of certain chemicals also contributing to soil pollution.
  • While health risk assessments indicated that workers' exposure levels were generally acceptable, the carcinogenic risk from PCDD/Fs was notably higher, suggesting the need for focused monitoring and control measures for these dioxins.
