Composition of PAHs in Biochar and Implications for Biochar Production [PDF]
ACS Sustainable Chemistry & Engineering, 2022 The content of polycyclic aromatic hydrocarbons (PAHs) in biochar has been studied extensively; however, the links between biomass feedstock, production process parameters, and the speciation of PAHs in biochar are understudied. Such an understanding is crucial, as the health effects of individual PAHs vary greatly. Naphthalene (NAP) is the least toxic
