バイオ炭は有機バイオマスを無酸素状態で熱化学変換して得られる炭素に富む生成物で、炭素隔離、土壌改良、環境修復、バイオマス廃棄物管理に応用される。近年、その環境リスク（PAHs、重金属、持続性フリーラジカルなど）も明らかになりつつある。本論文はバイオ炭の利点とリスクを体系的にレビューし、生産条件や施用方法の重要性を指摘している。
English
Biochar, produced from biomass pyrolysis, offers applications in carbon sequestration, soil improvement, and waste management. Recent research highlights both benefits (soil structure, nutrient retention) and risks (PAH formation, heavy metal contamination). This review systematically examines the trade-offs and emphasizes the role of production parameters and application practices.

📄 Abstract（原文）
Biochar, a carbon-rich product resulting from the thermochemical transformation of organic biomass feedstocks in the absence or limited availability of oxygen, is currently drawing much worldwide attention due to its multiple applications in carbon sequestration, soil improvement, environmental remediation, and biomass waste management. Initially, the focus of research was primarily on the technical possibilities of biochar production, its economic aspects, and its contribution to climate change mitigation through carbon sequestration and the promotion of sustainable agriculture. Nevertheless, recent research indicates the high complexity and dynamics of biochar interactions with the environment, driven by a combination of feedstock type, process conditions, biochar properties, and other-er factors. While biochar exhibits multiple positive effects, including improving soil structure, enhancing nutrient retention, promoting microbial activities, and remediating contaminants, several environmental risks associated with biochar application have also been identified, namely the formation of polycyclic aromatic hydrocarbons (PAHs), heavy metal contamination, creation of persistent free radicals, changes in soil chemistry, and modification of soil microbial community structure. Such risks are greatly related to production process parameters, treatment methods, and biochar application practices. Moreover, differences in feedstock choice, pyrolysis temperature, reactor design, biochar application rate, and analytical methods used make comparative analysis of results difficult.
