Surface and soil core samples from northeast China were analyzed for Pu isotopes. The measured 240Pu/239Pu atomic ratios 239 + 240Pu/137Cs activity revealed that the global fallout is dominant source of 137Cs at these sites. Migration behavior varying with land type human activities resulted in different distribution surface soils. A sub-surface maximum followed by exponential decline 240Pu concentrations was observed an undisturbed core, a total inventory 86.9 Bq/m2 more than 85%...
An analytical method was developed for simultaneous determination of ultratrace level plutonium (Pu) and neptunium (Np) using iron hydroxide coprecipitation in combination with automated sequential injection extraction chromatography separation accelerator mass spectrometry (AMS) measurement. Several experimental parameters affecting the performance were investigated compared including sample preboiling operation, aging time, amount coprecipitating reagent, reagent pH adjustment,...
ICP-MS/MS measurement with mass-shift mode using O 2 /He–He collision gas can effectively suppress the interference of polyatomic ions from interfering elements (Pb, Hg, Tl, etc. ) in analysis ultra-trace level 241 Am environmental samples.
在巢湖杭埠河流域中的古湖盆中心——三河圩区获取28.6 m长的湖相岩芯(SZK1507孔),利用AMS<sup>14</sup>C测年技术建立可靠的地层年代序列,通过对SZK1507孔738 cm以上段湖相沉积物平均粒径、磁化率、总氮(TN)、总有机碳(TOC)及C/N的综合分析,高分辨率重建了巢湖杭埠河流域全新世以来的古环境演变过程.结果表明,本区域的环境变化过程可以分为4个阶段,阶段Ⅰ(约10050—9700 cal.a B.P.)与阶段Ⅲ(约9250—5300 B.P.)气候较为湿润,巢湖水位较高,平均粒径、磁化率值较低,TN、TOC、C/N也偏低;阶段Ⅱ(约9700—9250 B.P.)与阶段Ⅳ(约5300 B.P.以来)气候干燥,巢湖水量减少,水位降低,平均粒径、磁化率值、TN、TOC、C/N均较高.一些全球范围内显著发生的气候突变事件在SZK1507孔沉积记录中也有体现,如9.3、8.2和4.2 ka B.P.事件等.将巢湖杭埠河流域10000...
