High-Temperature Biochar for Arsenic Remediation

Adding biochar produced at a high temperature may be an effective way to immobilize arsenic in sediment, according to researchers partially funded by the NIEHS Superfund Research Program (SRP). The study, led by Owen Duckworth, Ph.D., of the University of North Carolina at Chapel Hill SRP Center, in partnership with researchers from the Luiz de Queiroz College of Agriculture, University of São Paulo, Brazil, also provided further insight into the conditions that influenced the effectiveness of biochar for soil remediation.
