随着工农业的不断发展, 农田土壤中颗粒态新污染物(Particle emerging contaminants, PECs)的数量持续增加. PECs因其粒径和界面效应发生团聚-解团聚, 吸附-解吸, 溶解-重塑等迁移转化行为, 影响其环境归趋与健康风险. PECs的独特粒径效应, 使其不仅对生物体造成化学损伤, 还会对生物体产生物理损伤, 破坏生物体的细胞膜结构, 导致氧化胁迫. 此外, PECs还具有缓释特性, 通过溶解和生物降解等过程缓慢释放出有害物质, 产生长期胁迫. 根际作为土壤中物质进入植物的重要门户, 也是PECs在农田土壤中发生生物地球化学过程的关键微域. 本综述指出, PECs不仅可以直接被根系吸收和吸附, 还会刺激低分子量有机酸等根系分泌物的释放, 驱动根际微生物和土壤动物的群落组成与功能变化, 导致根际效应; 根际特殊的理化性质使得PECs的根际环境行为不同于非根际, PECs暴露促进还原态低分子量有机酸类根系分泌物的释放, 促进PECs的还原、重塑和颗粒分散; 根系分泌物促使根际成为土壤微生物和土壤动物的活动热区, 两者活跃的生理行为进一步增加了PECs的根际迁移与转化, 增加PECs的生物有效性和暴露风险. 明晰PECs的根际赋存与转化特征, 为其环境健康风险评估和原位植物修复提供理论基础.

Abstract Integrating innovation and environmental responsibility has become important in pursuing sustainable industrial practices the contemporary world. These twin imperatives have stimulated research into developing methods that optimize processes, enhancing efficiency effectiveness while mitigating undesirable ecological impacts. This objective is exemplified by emergence of biochar derived from thermo-chemical transformation biomass. review examines production their potential applications across various aspects iron steel industries (ISI). The technical, economic, implications integrating ISI were explored. Slow pyrolysis hydrothermal carbonization are most efficient for higher yield (25–90%). Biochar several advantages- heating value (30–32 MJ/kg), more porosity (58.22%), significantly larger surface area (113 m 2 /g) compared to coal coke. However, presence often reduces fluidity a coal-biochar mixture. findings highlighted implementation come with costs, primarily due expense substitute fuels traditional fossil fuels. economic viability societal desirability highly uncertain vary based on factors such as location, feedstock type, scale, pricing, among others. Furthermore, biomass supply chain another factor which determines its large scale implementation. Despite these challenges, there opportunities reduce emissions BF-BOF operations utilizing technologies. Overall, present study explored diverse aiming contribute ongoing manufacturing practices, underscoring significance shaping environmentally conscious future.

This study focuses on developing biochar-based adsorbents with high adsorption capacity and rapid rates for removing boron from aqueous solutions. Hydroxy-enriched biochar composites (BC (carboxylated biochar), BC-PDA (polydopamine loaded MBC-PDA magnetic BC-AlOOH (AlOOH BC-ZnCl2 (biochar modified by ZnCl2)) were synthesized specifically to utilize the superior of biochar. All using straightforward experimental techniques date palm cellulosic fibers as promising lignocellulose feedstock subjected various characterization methods. Boron kinetics, isotherms, mechanism, adsorbent recycling investigated batch experiments. The results showed values 14, 20.5, 21.5, 43.2, 44.2 mg/g BC, BC-PDA, MBC-PDA, BC-AlOOH, at 360 min. prominent was related abundant existence -OH functional groups BC surface abundance pores widely distributed throughout surface, facilitating chemical physical boron. exhibited a promoted ease recovery reusability.
