| 1 | 远洋系统中的持久性有机污染物(POPs)显示文摘有几项研究表明水生生物群中富营养化与持久性有机污染物(POPs)的吸收之间存在着相互作用。其主要概念是:由于营养物的过度排放,水生生态系统中生物量与生产增加,引起了一系列的变化,从而造成初级生产者(浮游植物)对POPs的吸收减少。其影响还会波及不同营养级的消费者。这一系列的变化可以间接地通过有机物沉淀的增加起作用,使污染物向底层的沉降流量增加,从而使污染物在底层被有机沉淀物所结合。这一系列的变化还会直接地起作用,作为'生长稀释'作用的后果,生长快速的浮游植物对POPs的吸收减少,使污染物在食物网中的转移减少。这种作用也可能是食物网结构改变的结果,而食物网结构的变化在寡营养型和富营养型的生态系统中极为不同。本文运用现有的有关不同营养状况的水生系统中POPs行为的知识,对波罗的海的富营养化与污染物之间的相互作用进行了讨论。波罗的海受到POPs的重度污染并正在富营养化是众所周知的。对湖泊进行调查的结果用于对实验室研究结果和在波罗的海的现场研究结果进行比较。 | Per Larsson Agneta Andersson Dag Broman Johan Nordbck Erik Lundberg 李应仁 | 2000 | AMBIO-人类环境杂志2000,29,4: | 3 |

| 4 | A review of halogenated natural products in Arctic,Subarctic and Nordic ecosystems显示文摘Halogenated natural products(HNPs)are organic compounds containing bromine,chlorine,iodine,and rarely fluorine.HNPs comprise many classes of compounds,ranging in complexity from halocarbons to higher molecular weight compounds,which often contain oxygen and/or nitrogen atoms in addition to halogens.Many HNPs are biosynthesized by marine bacteria,macroalgae,phytoplankton,tunicates,corals,worms,sponges and other invertebrates.This paper reviews HNPs in Arctic,Subarctic and Nordic ecosystems and is based on sections of Chapter 2.16 in the Arctic Monitoring and Assessment Program(AMAP)assessment Chemicals of Emerging Arctic Concern(AMAP,2017)which deal with the higher molecular weight HNPs.Material is updated and expanded to include more Nordic examples.Much of the chapter is devoted to“bromophenolic”HNPs,viz bromophenols(BPs)and transformation products bromoanisoles(BAs),hydroxylated and methoxylated bromodiphenyl ethers(OH-BDEs,MeO-BDEs)and polybrominated dibenzo-p-dioxins(PBDDs),since these HNPs are most frequently reported.Others discussed are 2,20-dimethoxy-3,30,5,50-tetrabromobiphenyl(2,20-dimethoxy-BB80),polyhalogenated 10-methyl-1,20-bipyrroles(PMBPs),polyhalogenated 1,10-dimethyl-2,20-bipyrroles(PDBPs),polyhalogenated N-methylpyrroles(PMPs),polyhalogenated N-methylindoles(PMIs),bromoheptyl-and bromooctyl pyrroles,(1R,2S,4R,5R,10E)-2-bromo-1-bromomethyl-1,4-dichloro-5-(20-chloroethenyl)-5-methylcyclohexane(mixed halogenated compound MHC-1),polybrominated hexahydroxanthene derivatives(PBHDs)and polyhalogenated carbazoles(PHCs).Aspects of HNPs covered are physicochemical properties,sources and production,transformation processes,concentrations and trends in the physical environment and biota(marine and freshwater).Toxic properties of some HNPs and a discussion of how climate change might affect HNPs production and distribution are also included.The review concludes with a summary of research needs to better understand the role of HNPs as“chemicals of emerging Arctic concern”. | Terry F.Bidleman Agneta Andersson Liisa M.Jantunen John R.Kucklick Henrik Kylin Robert J.Letcher Mats Tysklind Fiona Wong | 2019 | Emerging Contaminants2019,5,1: | 1 |

| 6 | Halomethoxybenzenes in air of the Nordic region显示文摘Halomethoxybenzenes(HMBs)are a group of compounds with natural and anthropogenic origins.Here we extend a 2002e2015 survey of bromoanisoles(BAs)in the air and precipitation at Rå€o on the Swedish west coast and Pallas in Subarctic Finland.New BAs data are reported for 2018 and 2019 and chlorinated HMBs are included for these and some previous years:drosophilin A methyl ether(DAME:1,2,4,5-tetrachloro-3,6-dimethoxybenzene),tetrachloroveratrole(TeCV:1,2,3,4-tetrachloro-5,6-dimethoxybenzene),and pentachloroanisole(PeCA).The order of abundance of HMBs at Råo was SBAs>DAME>TeCV>PeCA,whereas at Pallas the order of abundance was DAME>SBAs>TeCA>PeCA.The lower abundance of BAs at Pallas reflects its inland location,away from direct marine influence.Clausius-Clapeyron(CC)plots of log partial pressure(Pair)/Pa versus 1/T suggested distant transport at both sites for PeCA and local exchange for DAME and TeCV.BAs were dominated by distant transport at Pallas and by both local and distant sources at Rå€o.Relationships between air and precipitation concentrations were examined by scavenging ratios,SR=(ng m^(-3))precip/(ng m^(-3))air.SRs were higher at Pallas than Rå€o due to greater Henry's law partitioning of gaseous compounds into precipitation at colder temperatures.DAME is produced by terrestrial fungi.We screened 19 fungal species from Swedish forests and found seven of them contained 0.01e3.8 mg DAME per kg fresh weight.We suggest that the volatilization of DAME from fungi and forest litter containing fungal mycelia may contribute to atmospheric levels at both sites. | Terry Bidleman Agneta Andersson Eva Brorstrom-Lunden Sonia Brugel Lars Ericson Katarina Hansson Mats Tysklind | 2023 | Environmental Science and Ecotechnology2023,,1: | 0 |
| 7 | 波罗的海北部海冰生物区在养分和有机物循环中的作用显示文摘本文海冰的生化数据采集于波罗的海的波的尼亚湾(Hailuoto,芬兰)、波的尼亚海(Norrby,瑞典)和芬兰湾(Tvrminne,芬兰)三个海域。主要来源于2003~2006年开展BIREME项目期间的现场测量和实验,并补充了一些公开发表的相关数据。我们的重点是分析波罗的海海冰内生物活动是否有明显的区域性变化。波的尼亚湾海冰区域的叶绿素α浓度和细菌周转率都较低。然而,我们主要是在紧靠陆地的当年海冰内取样,明显缺失了海冰内最活跃的生物学系统,而这个系统一般都存在于残冰中(例如冰脊)。我们有限的数据表明,波罗的海的最北部海域内,在压力脊的冰固结层下方的受压冰块(keel blocks)和受压冰块间隙水内,藻类密度较高。尽管在顶层和冰内偶尔也能发现丰富的生物,但波的尼亚海和芬兰湾靠陆地海冰的最低层似乎是生物活性的中心。在积雪期间,冰中海藻光照受限,而对于冰底层的藻类,磷酸盐通常是限制性养分。细菌的生长明显被藻类有关的可溶性有机物的生产所控制,因为波的尼亚湾中的生长率低,但外来的可溶性有机物浓度高。在藻华发生期间,相比开放水体中的细菌活性,波的尼亚海和芬兰湾的细菌群落都有较高的周转率,和与藻华发生期间开放水体中相当的活动水平这意味着冬季海冰细菌群落有很强的物质处理能力。 | Jorma Kuparinen Harri Kuosa Agneta Andersson Riitta Autio Mats A.Granskog Johanna Ikvalko Hermanni Kaartokallio Kimmo Karell Elina Leskinen Jonna Piiparinen Janne-Markus Rintala Jaana Tuomainen 杨文波 | 2007 | AMBIO-人类环境杂志2007,36,2: | 0 |
