摘要
磷酸盐氧同位素(δ^(18)OP)技术是识别磷来源及迁移转化过程的有效工具。为加深对δ^(18)OP技术及其在沉积物领域应用的认识,提高δ^(18)OP技术在沉积物领域的应用水平,文章综述了δ^(18)OP技术在沉积物中应用的研究进展并展望了发展前景。在沉积物样品δ^(18)OP比值测定方法方面,沉积物磷形态分级方法的不统一以及沉积物中大量存在的有机物及杂质离子干扰是制约现阶段沉积物δ^(18)OP比值测定的主要瓶颈。在沉积物磷源识别及迁移转化过程探究方面,δ^(18)OP技术发挥了独特的技术优势,在磷源定量识别及微生物作用下的磷迁移转化过程方面发挥了重要的工具价值,但仍面临应用基础争议以及应用范围受限等问题。未来沉积物δ^(18)OP技术的应用在多环境介质δ^(18)OP信息协同解译,沉积物δ^(18)OP信息的可视化表征以及深度挖掘方面具有极大的发展前景。
Phosphate oxygen isotope(δ^(18)OP)technique is an effective tool to identify the source and migration process of phosphorus.In order to deepen the understanding ofδ^(18)OPtechnique and its application,this paper reviews the research progress and prospects ofδ^(18)OPtechnique in the area of sediment studies.Regarding theδ^(18)OPratio determination of sediment samples,the main bottleneck for the determination ofδ^(18)OPratio at present is the disunity of phosphorus speciation methods and the large amount of organic matter and impurity ions interference in the sediments.However,theδ^(18)OPtechnique plays an unique technical advantage in the identification of phosphorus sources and the exploration of phosphorus migration and transformation process in sediments,and has an important tool value in quantitative identification of phosphorus source and phosphorus migration and transformation process under microbial action.But it yet faces some difficulties such as basic controversy and limited application scope.As for the outlook for the application ofδ^(18)OPtechnique in sediment study area,it is expected in the future thatδ^(18)OPwill have great development prospects in the collaborative interpretation ofδ^(18)OPinformation from multiple environmental media,visual characterization and in-depth data mining based on sedimentδ^(18)OPinformation.
