Metadata record for data from ASAC Project 2357 See the link below for public details on this project.---- Public Summary from Project ----Contaminants like PCBs and DDE have hardly been used Antarctica. Hence, this is an excellent place to monitor global background levels of these organochlorines. In this project concentrations in penguins and petrels will be compared to 10 years ago, which will show time trends of global background contamination levels.Data set descriptionFrom several birds from Hop Island, Rauer Islands near Davis, samples were collected from preenoil (oil that birds excrete to preen their feathers. This preenoil was then analysed for organochlorine pollutants like polychlorinated biphenyls, (PCBs), hexachlorobenzene (HCB), DDE and dieldrin. The species under investigation were the Adelie penguin (Pygoscelis adeliae) and the Southern Fulmar (Fulmarus glacialoides). The samples were collected from adult breeding birds, and stored in -20 degrees C as soon as possible. The analysis was done with relatively standard but very optimised methods, using a gas-chromatograph and mass-selective detection. Data sheets:The data are available in excel-sheets, located at Alterra, The Netherlands (the affiliation of the PI Nico van den Brink.). Data are available on PCB153 (polychlorinated biphenyl congener numbered 153), hexachlorobenzene (HCB), DDE (a metabolite of the pesticide DDT), and dieldrin (an insecticide).The metadata are in 4 sheets (in meta data 2357.xls):1. 'Concentrations fulmars'2. 'Morphometric data fulmars'3. 'Concentrations Adelies'4. 'Morphometric data Adelies'The column headings are: 1. 'Concentrations fulmars'- Fulmar: bird number, corresponds with sheet 'morphometric data fulmars'.- PCB153: concentration of PCB-congener 153 (ng/g lipids)- HCB: concentration of hexachlorobenzene (ng/g lipids)- DDE: concentration of DDE (ng/g lipids)- Dieldrin: concentration of dieldrin (ng/g lipids)- Sample size weight of collected amount of preenoil2. Morphometric data fulmars- Fulmar: bird number, corresponds with sheet 'Concentrations fulmars'. - Bill Length (mm): length of bill (tip to base)- Head Length (mm): length of head (tip of bill to back of head)- Tarsus (mm): length of tarsus- Wing Length (cm): length of right wing- Weight (kg): weight of bird (without bag)3. 'Concentrations Adelies'Adelie: bird number, corresponds with sheet 'morphometric data Adelies'.- PCB153: concentration of PCB-congener 153 (ng/g lipids)- HCB: concentration of hexachlorobenzene (ng/g lipids)- DDE: concentration of DDE (ng/g lipids)- Dieldrin: concentration of dieldrin (ng/g lipids)- Sample size weight of collected amount of preenoil4.

---- 项目公开摘要 ----
多氯联苯(polychlorinated biphenyls, PCBs)与二氯二苯二氯乙烯(DDE)这类有机氯污染物在南极洲几乎未曾使用,因此南极洲是监测这类污染物全球背景水平的绝佳场所。本项目将对比10年前企鹅与海燕体内的污染物浓度,以此揭示全球背景污染水平的时间变化趋势。
数据集说明
本次研究在戴维斯站附近的劳尔群岛霍普岛采集了多只鸟类的羽饰油(preen oil,鸟类梳理羽毛时分泌的油脂)样本,并针对样本中的有机氯污染物开展分析,检测目标包括多氯联苯(PCBs)、六氯苯(hexachlorobenzene, HCB)、DDE以及狄氏剂(dieldrin)。本次研究涉及的物种为阿德利企鹅(Pygoscelis adeliae)与南方管鼻燕(Fulmarus glacialoides)。样本均采集自成年繁殖期鸟类,并在采集后尽快以-20℃的温度冷藏保存。本次分析采用相对标准但经过高度优化的气相色谱-质谱选择检测法(gas-chromatograph and mass-selective detection)。
数据集文件
本数据集以Excel表格形式存储,存放于荷兰的Alterra机构(项目首席研究员Nico van den Brink的所属单位)。本次公开的数据涵盖PCB153(编号为153的多氯联苯同系物)、六氯苯(HCB)、DDE(杀虫剂滴滴涕的代谢产物)以及狄氏剂(一种杀虫剂)的检测结果。
