Abstract
During biochar production, pyrolysis vapors released from biomass can interact with the porous aromatic biochar structure. Given the complex chemical composition of pyrolysis vapors, a wide range of organic compounds with different polarities and molecular mass can be retained in biochar with the potential to be released into the environment. The presence of these species will ultimately influence biochar quality and safety for soil applications. While our knowledge on the production, occurrence and fate of priority contaminants, such as polycyclic aromatic hydrocarbons, is increasing and led to the definition of threshold values, the relevance of non-regulated organic compounds has been less investigated. In particular, volatile organic compounds (VOCs) and water-soluble organic compounds (WSOCs) are worth of consideration because of their mobility into air and aqueous phase.
