A group of 2,6,10,15,19-pentamethyli- cosenes (PMIΔ) containing 1―5 unsaturated double bonds has been identified in the sea floor sediments from the Gulf of Mexico at the Green Canyon 238 *** PMIΔ compounds are distributed between nC22 and nC24 on the mass chromatogram of aliphatic fraction. Their δ 13C values are very much depleted in 13C and in the range of ?86.7‰ to ?115.5‰, whereas the δ 13C values of companion n-alkanes range from ?28.4‰ to ?34.6‰. These unsaturated PMIΔ com-pounds are typical biomarkers derived from the an-aerobic oxidation of methane mediated by meth-ane-oxidizing archaeal bacteria and indicative of the gas seeps or even the occurrence of gas hydrates in the deep sea sediments.

Two new blue light-emitting PPV-based conjugated copolymers containing both an electron-withdrawing unit (triazole-TAZ) and electron-rich moieties (carbazole-CAR and bicarbazole-BCAR) were prepared by Wittig condensation polymerization between the triazole diphosphonium salt and the corresponding dialdehyde monomers. Their structures and properties were characterized by FT-IR, TGA, DSC, UV-Vis, PL spectroscopy and electrochemical measurements. The resulting copolymers are soluble in common organic solvents and thermally stable with a T-g of 147degreesC for TAZ-CAR-PPV and of 157degreesC for TAZ-BCAR-PPV. The maximum photoluminescence wavelengths of TAZ-CAR-PPV and TAZ-BCAR-PPV film appear at 460 nm and 480 nm, respectively. Cyclic voltammetry measurement demonstrates that TAZ-BCAR-PPV has good electrochemical reversibility, while TAZ-CAR-PPV exhibits the irreversible redox process. The triazole unit was found to be an effective pi-conjugation interrupter and can play the rigid spacer role in determining the emission colour of the resulting copolymer.

Phenylalkanes with carbon numbers between 16 and 19, characterized by the main carbon-18, have been identified in the modern sediments collected from gas hydrate area from the Gulf of Mexico. The structure of phenylalkanes with four isomers for every carbon number was determined by means of their mass spectra and previous studies. The distribution of the series characterized by a low molecular mass was similar to the distribution of n-alkane, alkylcyclohexanes and alkylbenzenes in each sample. There were differences in the distribution of the phenylalkane series between the S - 1, S - 4, S - 7, S - 9 samples and the S - 8, S - 10 and S - 11 samples. The phenylalkanes might be derived from Archaea associated with anaerobic oxidation of methane （AOM） processes in S - 1, S -4, S -7 and S -9 samples according to their distribution resembled with the distribution of the extract from a type of Archaea. The distribution of alkylcyclohexanes and alkylbenzenes in S - 1, S - 4, S - 7 and S - 9 sample was found to be similar to each other. The odd-over-even predominance of alkylcyclohexanes was seen as the input of some bac- terial.

为探究珠三角地区秋季亚微米有机气溶胶(OA)的污染特征、健康风险及其城乡差异,本研究对基于黑碳高分辨率飞行时间气溶胶质谱仪(SP-AMS)观测的广州(城市)及鹤山(乡村)气溶胶数据进行了分析.结果显示,在城乡的两次秋季观测期间,PM,平均质量浓度分别为(29.87±20.11)μg·m^(-3)和(40.08±16.05)μg·m^(-3),其中OA占比最高,分别为57.4%和52.1%.基于正交矩阵因子分析法(PMF)进行来源解析,发现在珠三角城乡两地二次有机气溶胶都是OA的首要组分,分别占64.0%和66.7%.城市地区OA受日间光氧化反应贡献明显,而乡村地区OA在夜间至清晨出现显著抬升,可能与夜间二次生成相关.相对湿度(RH)升高指示的液相反应及日间光氧化对城市低氧化态OA生成均有促进作用,光氧化也能促进乡村低氧化态OA的日间生成,而夜间SOA(Night-OA)则主要在高RH的条件下贡献更为显著.基于模型计算了亚微米级OA在人体呼吸系统中的分粒径沉积通量,发现其在肺泡区域沉积通量最大,两地沉积通量的粒径分布呈现双峰分布,但城区OA在小粒径(120 nm)的沉积峰值更加突出,因此可能具有更大的健康风险.

Chemical speciation of fine particles or PM2.5 collected on filters is still a cosily and time- consuming task. In this study, filter-based PM2.5 samples were collected during November-December 2013 at four sites in guangzhou, and the major components were fast screened （~ 7 rain per filter sample） by Attenuated Total Reflectance （ATR）-Fourier Transform Infrared Spectroscopic （FTIR） in comparison with that measured by organic carbon/Element carbon （OC/ EC） analyzer and Ion Chromatography （IC）. The concentrations of nitrate, ammonium, sulfate, primary organic carbon （POC） and secondary organic carbon （SOC） measured by OC/EC and IC analyzers were better correlated with their infrared absorption peak heights at 1320 cm 1 for nitrate, 1435, 3045 and 3215 cm^-1 for ammonium, 615 cm^-1 for sulfate, 690, 760 and 890 cm^-1 for POC and 1640 and 1660 cm^-1 for SOC respectively, during polluted days （PM2.5 〉 75 μg/m^3） than during clean days （PM2.5〈 75 μg/m^3）. With the evolution of a haze episode during our field campaign, the concentrations of the major PM2.5 components displayed consistent variations with their infrared absorption peak heights, suggesting ATR-FTIR could be a fast and useful technique to characterize filter-based PM2.5 compositions particularly during pollution events although cautions should be taken when PM2.5 levels are low. Notably, elevated PM2.5 mass concentrations occurred with enhanced ratios of [NO^-3][SO^2-4] and [NH^＋4]/[SO^2-4], implying that nitrogenous components play vital roles in the PM2.5 pollution events in the study region.

近年来随着我国页岩气勘探领域从上扬子地区逐步扩展到中扬子地区,位于中扬子的宜昌、神农架地区由于广泛发育五峰-龙马溪组黑色页岩而受到了较多的关注。本次研究通过对比鄂西宜昌、神农架地区与川东焦石坝地区五峰-龙马溪组黑色页岩的地球化学特征、孔隙结构特征和构造保存条件等因素,综合评价宜昌、神农架地区五峰-龙马溪组富有机质页岩的含气性。结果表明,神农架背斜北翼八角庙剖面五峰-龙马溪组黑色页岩发育以微孔和介孔为主的有机质孔隙,与宜昌和焦石坝地区五峰-龙马溪组黑色页岩孔隙特征相似,具备良好的页岩气储集空间。宜昌、神农架地区与焦石坝地区的五峰-龙马溪组黑色页岩在厚度、热演化程度、矿物组成、页岩孔隙类型和分布特征上有很大的相似性,但在页岩的分布范围、有机质丰度及类型上均存在差异。另外,宜昌、神农架地区受宜昌上升运动等构造活动的影响,在古隆起中心部位的五峰-龙马溪组遭受严重剥蚀破坏,页岩气保存条件较差,仅在古隆起周缘地区还发育保存条件较好的富有机质页岩。综合认为位于黄陵隆起东缘的宜昌斜坡带是今后鄂西、渝东地区页岩气勘探开发的有利地区。
