1湿地和湖泊:氮的储集库显示文摘近15年中,由于过量氮的负荷造成的富营养化在瑞典南部沿海水域已成为越来越严重的问题。现在的政策规定的目标是到1996年以前人为排放氮要减少50%。在这方面主要的问题是从农田排出的氮。因此,作者研究了瑞典南部农业区不同类型湿地对氮的存储容量,以确定湿地是否可用于减少从农田排放到近海海洋生态系统中去的氮。同时也对不断增加氮负荷的湖泊中氮的持留机制进行了研究。其结果表明,在湿地氮的去除主要决定于脱氮作用。此外,在湖泊中的沉积作用也是举足轻重的。水的存留时间乃是去除氮最关键的因素。因此,尽管氮存留率(每平方米氮的持留量)在湿地中是相当大的,但湖泊去除的氮还是比小的湿地要更多些。池塘被推荐为去除氮的最合适的湿地类型。在瑞典南部用湿地作为减少氮迁移的一种方法,其最大的问题是由于冬季高流量期间,氮存留在湿地中的时间太短,而使生物去除过程,如脱氮作用不能充分发挥其效用。在集水区中在大尺度范围中建立大量湿地最多可能使氮的迁移减少约15%。在多数情况中,其结果可能更小些。Mats Jansson Rune Andersson Hans Berggren Lars Leonardson 汪安璞 1994人类环境杂志1994,23,6:4
2A Lesion-Mimic Syntaxin Double Mutant in Arabidopsis Reveals Novel Complexity of Pathogen Defense Signaling显示文摘损害模仿 Arabidopsis 异种, syp121 syp122,组成地表示表明小径的水杨酸酸(SA ) 并且有低穿入抵抗到粉的霉真菌。损害模仿显型的基因分析在植物扩展了我们规划房间死亡(PCD ) 的理解。在 syp121 syp122 表明基因的 SA 的 Inactivation 仅仅部分救损害模仿显型,显示另外的防卫贡献 PCD。整个染色体 transcriptome 分析证实了那知道的导致 SA 的抄本,以及众多的其它病原体反应抄本,在 syntaxin 基因的 inactivation 以后是起来调整的。syp121 syp122 的 suppressor 异种分析表明 FMO1, ALD1,和 PAD4 为损害开发是重要的。EDS1, NDR1, RAR1,和 SGT1b 的变异的等位基因部分也救了损害模仿显型,建议那变异的 syntaxin 基因刺激 TIR-NB-LRR 和 CC-NB-LRR-type 电阻。syntaxin 两倍大美人加强了粉的导致霉的象 HR 一样回答。发信号的这要求的功能的 PAD4 然而并非功能的 SA。然而,发信号的 SA 加强了 PAD4 依赖的象 HR 一样反应。四倍的异种的分析建议 EDS5 和 SID2 授与分开的 SA 独立的发信号功能,并且那 FMO1 和 ALD1 调停 NPR1 依赖的 SA 独立的信号。这些研究加亮多重小径的贡献到防卫和点到他们的相互作用的复杂性。Ziguo Zhang Andrea Lenk Mats X.

16A 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 2019Emerging Contaminants2019,5,1:1
