| 1 | 南黄海表层沉积物中邻苯二甲酸酯的分布特征显示文摘采用GC-FID分析测定了南黄海(SYS)表层沉积物样品中的4种邻苯二甲酸酯(PAEs),探讨了影响该类污染物分布的因素,并对其潜在生态危害做出初步判断。研究海域4种PAEs总含量在(311.4~6 156.5)×10-9之间,平均浓度为1 636.3×10-9,高值区主要分布在南黄海中部。二丁酯(DBP)检出浓度最高,介于(159.7~5 499.3)×10-9,二正辛酯(DnOP)浓度最低,为(2.2~81.1)×10-9,二甲酯(DMP)和二乙酯(DEP)含量平均值分别为159.5×10-9和74.2×10-9。4种PAEs浓度高值区同样主要集中在南黄海中部,不同组分之间的分布规律稍有差异。PAEs本身的性质、沉积物的特性、水动力条件以及周边环境都会影响PAEs的分布,其中沉积物中TOC的含量是影响其分布的重要因素之一。生态风险评价结果表明,大部分站位只有DBP超出警戒值,但低于其风险评估低值(ERL),初步判断南黄海海域目前这4种PAEs的生态危害较小。 | 李孟芳 张大海 段晓勇 邓伟 李先国 | 2014 | 海洋环境科学2014，33，5： | 9 |
| 2 | 地表水中有机氯农药和多氯联苯的研究概述显示文摘地表水污染已成为一个影响公共安全和健康的重要社会问题,而水环境中对人类和生态系统威胁最大的是有机污染物,尤其是有机卤素污染物。目前对城市地表水的研究仅限于常规检测、重金属、无机盐和有机污染物,而对水体中卤素污染物的种态及化学组成的研究却鲜有报道。主要针对地表水中的有机氯农药和多氯联苯,研究其在国内外的检测方法、含量及分布规律,为更好的履行斯德哥尔摩公约提供有力的根据,具有重要的意义。 | 解琼玉 徐殿斗 马玲玲 郎春燕 | 2013 | 科学技术与工程2013，21，33： | 6 |
| 3 | Historical records of polycyclic aromatic hydrocarbon deposition in a shallow eutrophic lake:Impacts of sources and sedimentological conditions显示文摘Sediment core samples collected from Lake Chaohu were analyzed for 15 priority polycyclic aromatic hydrocarbons(PAHs)to assess the spatial and temporal distributions of the PAHs during lacustrine sedimentary processes and regional economic development.Assessing the PAH sedimentary records over an approximately 100-year time span,we identified two stages in the PAH inputs and sources(before the 1970 s and after the 1970s)in the eastern lake region near a village,whereas three stages(before the 1950 s,1950s–1990s and after the1990s)were identified in the western lake region near urban and industrial areas.Rapid increases in the PAH depositional fluxes occurred during the second stage due to increased human activities in the Lake Chaohu basin.The composition and isomeric ratios of the PAHs revealed that pyrolysis is the main source of PAHs in this lake.Strong positive relationships between PAH concentration and the total organic carbon concentration,sediment grain size(< 4 μm),as well as the local population and Gross Domestic Product indicated that the sedimentary conditions impact the depositional characteristics of the PAHs;simultaneously,socioeconomic activities,such as energy consumption and the levels of urban industrialization and civilization,affect both the composition and abundance of the PAHs. | Chaocan Li Shouliang Huo Zhiqiang Yu Wei Guo Beidou Xi Zhuoshi He Xiangying Zeng Fengchang Wu | 2016 | Journal of Environmental Sciences2016，28，3： | 6 |
| 4 | Petroleum hydrocarbon concentrations in eight mollusc species along Tamilnadu coast, Bay of Bengal, India显示文摘Eight mollusc species and sediment samples collected from three different stations along Tamilnadu coast, Bay of Bengal, India were analysed for the levels of petroleum hydrocarbons to elucidate the status of the petroleum residues in mollusc meant for human consumption. The concentrations of petroleum hydrocarbons in sediments along Tamilnadu coast varied from 5.04–25.5 μg/g dw (dry weight). High concentration of petroleum hydrocarbons in the sediment of Uppanar estuary (25.5 ± 1.45 μg/g dw) was perhaps land and marine based anthropogenic sources of this region. The petroleum hydrocarbon residues in eight mollusc species collected from Uppanar, Vellar and Coleroon estuaries varied between 2.44–6.04 μg/g ww (wet weight). Although the concentration of petroleum hydrocarbons in sediment of the Uppanar region was markedly higher than the background, the petroleum hydrocarbon residues in mollusc collected from Uppanar estuary did not suggest bioaccumulation. The results signified that industrial growth has affected the aquatic environments and regular monitoring will help to adopt stringent pollution control measures for better management of the aquatic region. | S.

| 5 | Historical records and the sources of polycyclic aromatic hydrocarbons in the East China Sea显示文摘The coastal cities are the most advanced regions in China.In the past few decades,the environment changed very significantly due to large scale human activities in the coastal regions.Polycyclic aromatic hydrocarbons (PAHs)in three dated sediment cores from the west coast of the Yellow Sea (core A01),the Yangtze River estuary (YRE;core A02)and the Oujiang River estuary (ORE;core A03)were analyzed to reconstruct the environmental evolutionary process of the east China coastal region over the past century. In the three cores,PAHs concentrations were increased rapidly.Lower concentrations of PAHs were measured in core A02 than in cores A01 and A03.The vertical variation of PAHs in the YRE Was dominated by the petrogenic sources.Historical records of PAHs in the ORE were controlled by pyrolytic sources.PAHs on the west coast of the Yellow Sea were contributed by the two sources. | Xiao-yong Duan Yan-xia Li Xian-guo Li Ping Yin | 2018 | China Geology2018，1，4： | 2 |
| 6 | 海运船舶尾气洗涤废水中多环芳烃对海洋污染的研究现状及展望显示文摘分析了海运船舶尾气洗涤废水排放对多环芳烃(PAHs)类污染物的海洋富集行为的影响以及对PAHs控制的制约因素和净化技术发展现状。PAHs的海洋富集趋势与船舶的发动机尾气排放行为呈正相关性,且船舶尾气洗涤废水排放加速了PAHs向海洋中富集。国际海事组织(IMO)尚未对在PAHs中占比大且毒性强的烷基化多环芳烃进行立法限制,但单方面采取措施禁止船舶尾气洗涤废水在其所属海域排放的国家和地区日益增多,洗涤废水排放的PAHs类污染物亟须净化处理。将高级氧化光催化技术应用于洗涤废水排放的PAHs净化具有发展前景。我国应抓住机遇,大力开展针对海洋PAHs的排放限制立法以及船舶尾气洗涤废水处理先进技术的研究,这对于提升我国海事管理水平、增大国际话语权,以及保护海洋生态安全具有重要意义。 | 张丽 杨懿 顾毅康 张文婷 刘瑞杰 | 2022 | 海洋通报2022，41，5： | 1 |
