冉勇(RAN YONG)

冉勇:1963年10 月生,博士,中国科学院研究生院教授,博士导师。1991年-1993年在中国科学院地化所环境地球化学国家重点实验室做博士后;1995年-1997年在澳大利亚Monash大学和西澳大利亚大学做客座研究;1997年12月起在中国科学院广州地化所有机地球化学国家重点实验室工作,先后赴美国、德国、瑞士进行短期合作研究和学术访问。现任国际著名环境毒理和化学期刊(Environental. Toxicology and Chemistry)编委,《矿物岩石地球化学通报》编委。主要从事水、陆环境中毒害有机污染物的来源、迁移、归宿及修复技术等领域研究。首次揭示微孔充填机理在干酪根吸附中的重要作用,以及微孔扩散对吸附动力学的制约。运用有机岩石学和13C-核磁共振光谱首次证实Borden含水砂有机质是以不同形式干酪根显微组分组成,表明干酪根、碳黑、不同分子量腐殖酸等聚合有机质在非线性吸附-解吸和解吸滞后中有重要作用,而泥炭中的腐殖质和干酪根是导致非线性吸附的原因,以及泥炭有机质的微孔性(nm微孔)在疏水有机污染物吸附容量和解吸滞后现象的重要性。这些研究成果,不仅在科学上深化了对天然有机质本身及其与有机污染物相互作用机制的认识,而且表明地质吸附剂有机质的非均匀性在有机污染物的吸附/解吸和归宿等环境行为方面的重要性。较系统地研究了珠江三角洲水/沉积物中内分泌干扰物和珠江三角洲土壤中多种有机污染物的污染状况和环境归宿行为。进一步揭示了干酪根和碳黑等聚合有机质在土壤/沉积物中有机污染物的分布、迁移和归宿的重要作用。

研究领域:

有机污染物在水陆环境中的迁移、转化和归宿等研究。
