Abstract

Biochar-derived dissolved organic matter (BDOM) is a significant carbon component released from biochar, characterized by high reactivity and mobility. It has substantial potential in soil remediation, agriculture, and environmental protection. BDOM plays a crucial role in shaping microbial community structures, enhancing soil fertility, and improving water quality. However, the release of BDOM may also worsen environmental issues, such as pollutant mobilization, shifts in microbial community composition, and water eutrophication, impacting ecosystem stability. Despite BDOM is importance, the specific mechanisms underlying its environmental applications are not well understood. Thus, investigating BDOM's environmental behavior and optimizing biochar preparation and application strategies are essential for maintaining healthy soil and aquatic ecosystems. This article reviews the factors influencing BDOM, its characterization methods, environmental behavior, and mechanisms. Furthermore, we emphasize the necessity of establishing standardized biochar regulatory frameworks and quantifying BDOM's ecological thresholds to balance its benefits and risks. These insights provide a scientific basis for optimizing biochar applications and mitigating potential environmental concerns.

期刊介绍： The Journal of Water Process Engineering aims to publish refereed, high-quality research papers with significant novelty and impact in all areas of the engineering of water and wastewater processing . Papers on advanced and novel treatment processes and technologies are particularly welcome. The Journal considers papers in areas such as nanotechnology and biotechnology applications in water, novel oxidation and separation processes, membrane processes (except those for desalination) , catalytic processes for the removal of water contaminants, sustainable processes, water reuse and recycling, water use and wastewater minimization, integrated/hybrid technology, process modeling of water treatment and novel treatment processes. Submissions on the subject of adsorbents, including standard measurements of adsorption kinetics and equilibrium will only be considered if there is a genuine case for novelty and contribution, for example highly novel, sustainable adsorbents and their use: papers on activated carbon-type materials derived from natural matter, or surfactant-modified clays and related minerals, would not fulfil this criterion. The Journal particularly welcomes contributions involving environmentally, economically and socially sustainable technology for water treatment, including those which are energy-efficient, with minimal or no chemical consumption, and capable of water recycling and reuse that minimizes the direct disposal of wastewater to the aquatic environment. Papers that describe novel ideas for solving issues related to water quality and availability are also welcome, as are those that show the transfer of techniques from other disciplines. The Journal will consider papers dealing with processes for various water matrices including drinking water (except desalination), domestic, urban and industrial wastewaters, in addition to their residues. It is expected that the journal will be of particular relevance to chemical and process engineers working in the field. The Journal welcomes Full Text papers, Short Communications, State-of-the-Art Reviews and Letters to Editors and Case Studies
