為了解決arctic contaminants 的問題,作者Qu, Bo 這樣論述:

Arctic marine ecosystems are largely impacted by changes associated with global warming. The sea ice in Greenland Sea plays an important role in regional and global climate system. The book investigate the relationships between phytoplankton biomass, measured using remotely sensed chlorophyll-a (CHL

), aerosol optical depth (AOD) and sea-ice cover (ICE) in the Greenland Sea (20 W-10 E, 65-85 N) over the period 2003-2012. First hand Satellite data was used to do correlation analysis. Enhanced statistics methods, such as lag regression method and cointegration analysis method are used for correla

tion and regression analysis between 2 variables (up to 3 variables). ARMA model was used to prediction time series in the future 3 years. The book not only gives outline of ecosystem in Greenland Sea, how the ice impact to the local ecosystems, but also provides valuable statistical methods on anal

ysis correlations and predicting the future ecosystems. Dr. Bo Qu (Ph D. from Napier University in 1999 in Edinburgh), Associate Professor works in School of Science, Nantong University, China. Her PhD research was the use of fractional Brownian motion in the modelling of the dispersion of contami

nants in fluids. After half year’s work in Queen’s University of Belfast on Irish Sea Modeling, she went to Hong Kong University, did hydraulic modeling for Hong Kong Coastal water, especially the 1998 Hong Kong massive red tidals research using Delft 3D. She then went to Griffith University, Brisba

ne, Australia did Environmental modeling especially on dimethylsulphide (DMS) research in Arctic Ocean. Her research interests including Polar Ecosystem research; DMS modelling especially on parameter calibrations using genetic algirithms; Hydraulic Modeling for coastal water and oceanic surface; St

ochastic Modeling, especially particle tracking modeling using fractional Brownian motion.Now she is undertaking the National Natural Science Funding Project to set up the environmental modeling in Arctic Ocean.

膠凝時間對可能用作柴油吸收劑藻酸鹽氣凝膠吸收率的影響

為了解決arctic contaminants 的問題,作者葉羅納 這樣論述:

漏油是海洋生態系統及其周邊的嚴重問題之一,已有一些技術可緩解這一問題,其中之一就是吸收。本研究探討使用自然可得的生物質,即海藻酸鈉,作為吸收劑合成的前體。雖然海藻酸鹽吸收劑合成和改性的各種方法已被廣泛研究,但關於凝膠時間對其性質和吸收率的影響所知甚少。本研究使用 1 w/v % 海藻酸鈉與 1 wt% CaCl 交聯 0、3、6 和 12 小時所得之海藻酸鹽氣凝膠(AA)分別稱為 AA-0、AA-3、AA-6、AA-12。凝膠時間對 AA 物理化學性質的影響藉由電感耦合等離子體發射光譜儀 (ICP-OES) 分析、使用壓汞孔隙率計 (MIP) 量測總孔體積和使用萬能測試機(UTM)評估其抗壓

強度;結果顯示凝膠時間越長,表觀密度和鈣含量增加,從而增加了 AA 氣凝膠的最大應力。本研究使用柴油為模型吸收物。在合成的 AA 中,AA-3 具有最高的吸收能力(Q=11.20 g/g)、可重複使用性(最多 29 次循環)和再吸收能力(Q= 4.09 g/g)。通過添加單寧酸和十二烷硫醇進行表面改性,將親水性 AA-3 轉化為更疏水的 AA-3Do。傅里葉變換紅外 (FTIR) 數據證實了在 AA-3Do 中成功地加入了添加劑。 AA-3Do 顯示能極快速吸收柴油,初始速率 ((R_0) 為 1.12E+09 g/g.s,但緩慢地吸收水 (R_0 = 27.6526 g/g.s),在其動力學

數據中觀察到 2 吸收平衡。擬二級動力學和兩步線性驅動力 (LDF) 模型分別可最佳地描述柴油和水的吸收。本研究還探討了可重複使用性,並證明了 AA-3Do 偏好吸收柴油勝過吸收水。

為了解決arctic contaminants 的問題,作者Orbaek, Jon-borre (EDT)/ Kallenborn, Roland (EDT)/ Tombre, Ingun 這樣論述:

This book addresses the significant environmental changes experienced by high latitude and high altitude ecosystems at the beginning of the 21st c- tury. Increased temperatures and precipitation, reduction in sea ice and glacier ice, the increased levels of UV-radiation and the long-range tra- porte

d contaminants in arctic and alpine regions are stress factors that challenge terrestrial and aquatic ecosystems. The large natural variation in the physical parameters of these extreme environments is a key factor in structuring the biodiversity and biotic productivity, and the effect of the new st

ress factors can be critical for the population structures and the - teraction between species. These changes may also have socio-economic effects if the changes affect the bio-production, which form the basis for the marine and terrestrial food chains. The book is uniquely multidisciplinary and pro

vides examples of va- ous aspects of contemporary environmental change in arctic and alpine - gions. The 21 chapters of the book are organised under the fields of -Climate change and ecosystem response, -Long range transport of poll- ants and ecological impacts, and -UV radiation and biological effe

cts, each also including aspects of the -Socio-economic effects of environmental change. The introductory chapter presents and explains the internal c- nection and integration of all chapters. The added value of these reviews and review-like manuscripts from different disciplines hopefully yields ne

w information about the integrated aspects of environmental change.

東北季風期間台灣竹山地區雲霧水之PCDD/Fs與PCBs沈降通量

為了解決arctic contaminants 的問題,作者賴圖妳 這樣論述:

在东北季风期间,来自东亚和中亚的空气污染物被输送到台湾。由于台湾北部多云天气,污染可能已被云清除。在这项研究中,在台湾北部的山竹进行云/雾水采样,使用被动和主动雾收集器来研究多氯二苯并二恶英和多氯二苯并呋喃的数量、清除机制和沉积通量(PCDD/Fs) 和多氯联苯 (PCBs)。云/雾水样中 PCDD/F 的平均浓度为 0.861 pg WHO-TEQ/L(被动样品)和 1.30 pg WHO-TEQ/L(主动样品),而 PCB 浓度分别为 0.0213 pg WHO-TEQ/L 和 0.0462 pg WHO -TEQ/L,分别。云/雾水的PCDD/Fs TEQ 值比台北市区雨中PCDD/F

s 的TEQ 值高出三个数量级。后向轨迹模型显示,高集中事件起源于东亚和中亚。颗粒相 PCDD/Fs 和 PCBs 的清除系数和清除率高于气相,表明云/雾水对颗粒物 (PM) 的清除。 PCDD/Fs 通过雾的平均沉积通量为 1.12 pg TEQ WHO m-2 h-1,而 PCBs 的平均沉积通量为 0.0364 pg TEQ WHO m-2 h-1。通过雾的 PCDD/Fs 沉降通量比先前研究中报告的总 PCDD/Fs 大气沉降通量(干 + 湿沉降)大一个数量级。较高的沉积通量可能导致山竹附近环境隔间的污染物含量升高。
