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.

Globally, water resources are facing serious threat owing to the increasing concentration of various emerging contaminants. Indiscriminately discarded and/or excreted antibiotics and their residues one such Since long-term persistence these in environment is responsible for developing antimicrobial (antibacterial) resistance organisms, removal from / wastewater essential. Hence, scientists attempting evolve novel methods encounter water. One method adsorption onto a suitable matrix thereby reducing Biochar has been proven act as adsorbent contaminants; however, efficiency remains concern. Therefore, functionalization biochar using physical chemical modifications, was developed technique that can help efficient antibiotics. Functionalization seen improve properties biochar; as, pore volume, diameter, surface morphology, functional groups, polarity, porosity etc. In this review, functionalized biochars have explored understand efficacy mechanism residues. The discussion includes methods, impact property modifications on antibiotic residues, mechanism. addition, cost-effectiveness, economy process, its environmental effects also dealt with.
