| 1 | Branched alkanes with quaternary carbon atoms in Chinese soils: Potential environmental implications显示文摘Lipids extracted from 26 modern soils collected from different climate zones in China and Mongolia are analyzed using gas chromatography- mass spectrometry. These extracts contain pseudo- homologous families of 5,5-diethylalkanes (5,5- DEAs), 6,6-diethylalkanes, 5-butyl-5-ethylalkanes and 6-butyl-6-ethylalkanes, which are first detected in modern soils. All these pseudohomologous series display exclusively odd or exclusively even carbon numbers, clearly indicating a biosynthetic origin, and their carbon number distributions generally covary. The distributions of 5,5-DEAs exhibit strong regional variations, correlated with the spatial distributions of climate and vegetation. The lower molecular weight 5,5-DEAs, maximizing at C21 or C23, dominate in southeast and southwest China samples, while the higher molecular weight 5,5-DEAs with a mode at C29 dominate in cold, arid northwest China and Mongolia. The results demonstrate that the distribution of 5,5-DEAs can serve as a new independent proxy, indicating variations in soil ecosystems and climates, just like the well-known proxy of n-C15—21/n-C22—33 ratios. | BAI Yan FANG Xiaomin WANG Yongli Fabien Kenig CHEN Xiuling WANG Youxiao | 2006 | Chinese Science Bulletin2006，51，9： | 6 |
| 2 | 现代土壤中含季碳支链烷烃的分布特征及环境意义显示文摘利用色谱质谱(GC-MS)技术对中国及蒙古国不同气候区的26个深约20cm表层土壤中的类脂物进行了系统分析.讨论了在现代土壤中首次发现的含季碳的支链烷烃系列化合物,如5,5-二乙基烷烃、6,6-二乙基烷烃、5-丁基,5-乙基烷烃和6-丁基,6-乙基烷烃等.它们每个系列都只有奇碳或偶碳分布,明显指示生物来源,其碳数分布具有协变性.其中5,5-二乙基烷烃的分布同正构烷烃一样具有规律性的空间变化趋势,与气候和植被的空间分布有很好的一致关系.在湿热的东南和西南地区其低碳数组分占优势,主峰基本上为C21或C23;而在寒冷干旱的西北地区及蒙古国高碳数组分丰度较高,主峰基本上为C29.研究结果证明:和正构烷烃的ΣC?21/ΣC+21一样,5,5-二乙基烷烃的高低碳数分布优势作为一个新的独立指标,可以敏感地指示土壤生态和气候的变化. | 白艳 方小敏 王永莉 Fabien Kenig 陈秀玲 王有孝 | 2006 | 科学通报2006，51，4： | 5 |
