Geochemistry of surface sediments from the continental shelf of the East China Sea and small rivers of SE China: Constraints on chemical weathering and provenance [PDF]
, 2015 沉积物元素地球化学特征可为沉积环境演化历史提供重要信息，包括沉积物物源、物源成分特征、物源区岩石风化侵蚀程度、成岩作用、沉积物传输、沉积过程及古气候变化等。本研究于东海大陆架，瓯江、闽江和晋江河口共采集79个表层沉积物样品，分析其常微量元素地球化学特征并探讨物源区性质及化学风化特征。UCC和UC-YC标准化蛛网图表明，CaO、Na2O、Ba和Sr呈现出不同程度的亏损，而Rb元素则轻微富集。硅酸盐风化指数(CIA、PIA和CIW)及三角形图(A-CN-K、(A-K)-C-N和A-CNK-FM ...

Nitrogen Transports and Transformations in Mangrove Sediments using Nitrogen Isotope Techniques in China [PDF]
, 2012 人类活动对生态系统的影响日益扩大，过量施肥、化石燃料的燃烧等引发的氮(N)负荷迅速增加。陆地生态系统过剩的N通过流域汇集至河口和海岸，威胁着海洋生态系统的健康。目前，全球N循环正致力于揭示河口和海岸地区N的源汇格局及主导机制。红树林湿地广泛分布于热带、亚热带河口和海岸地区，作为陆源营养盐入海过渡带，在缓解陆源N输入方面扮演着重要角色，成为了研究的热点。 本研究利用N稳定同位素技术，将现场培养与室内模拟培养相结合，揭示了我国东南沿海典型河口和海湾红树林湿地沉积物总氮沉积、固氮作用、反硝化作用 ...

Development of Simultaneous Determination Method for Multi-categorized Organic Pollutants in Sediment and Its Application to the Study of Combined Pollution Characteristics of the Jiulong RiverEstuary [PDF]
, 2015 我国沿海社会经济相对发达，河口区域承接着流域各类生产、生活活动排放的大量有机污染物。沉积物作为水环境的重要组成部分，既是污染物的主要归宿，又是污染物迁移的载体和二次污染来源。河口沉积物中频繁检出的多环芳烃（PAHs）、多氯联苯（PCBs）、多溴联苯醚（PBDEs）、农药和抗生素等有机污染物严重威胁着河口生态环境。本论文以PAHs、PCBs、PBDEs、农药和抗生素5类122种有机污染物为目标物，运用色谱-串联质谱技术建立了其在沉积物中的分组同时分析方法，并且应用于福建九龙江河口表层和柱状沉积物样品的分析，
