| 1 | 贵阳市大气颗粒物(PM_(2.5))污染特征及气象参数的影响显示文摘运用连续颗粒物采样仪(URG Model 2000-01J)对贵阳市城区大气颗粒物PM2.5进行了连续3个月(9-11月)的采集与分析,探讨了PM2.5的浓度分布特征、气象条件的影响。结果显示,贵阳市大气颗粒物PM2.5的平均质量浓度为53±27μg/m^3,变化范围为3.7-186μg/m^3;初步推断大气颗粒物PM2.5的污染来源主要是燃料燃烧、生物质燃烧、汽车尾气等人为源;相对湿度、风速、风向、温度等气象条件是影响大气颗粒物浓度及分布的重要因素。 | 刘娜 冯新斌 Landis Matthew 陈卓 仇广乐 | 2014 | 地球与环境2014,42,3: | 29 |
| 2 | 贵阳市大气黑碳污染特征显示文摘利用连续颗粒物采样仪(URG Model 2000-01 J)和黑碳仪(Aethalometer)对贵阳市城区2008年9—11月大气黑碳浓度进行了连续观测,结果表明,贵阳市城区秋冬季大气24h黑碳浓度变化范围为1.6~12μg.m-3,平均值为4.1μg.m-3;12 h黑碳浓度观测值主要分布在2~5μg.m-3,白昼黑碳浓度变化范围介于1.9~9.2μg.m-3,平均值3.9μg.m-3,夜间黑碳浓度变化范围0.48~15μg.m-3,平均值4.3μg.m-3;黑碳浓度与大气PM2.5浓度变化一致,呈正相关关系(r=0.84,P〈0.0001,n=178),大气黑碳浓度的变化趋势还明显受相对湿度、温度和风速的影响。 | 仇广乐 刘娜 冯新斌 LANDIS Matthew 商立海 付学吾 | 2011 | 生态学杂志2011,30,5: | 9 |
| 3 | 贵阳市大气降水中汞的分布特征显示文摘于2008年7—9月对贵阳市中心城区采集的21个大气降水进行了总汞、甲基汞及阴、阳离子浓度的测定,分析了大气降水中总汞与阴阳离子间的相互关系。结果表明:大气降水中总汞的平均含量为18 ng.L-1,变化范围为0.4~57.4 ng.L-1;甲基汞的平均含量为0.07 ng.L-1,变化范围为0.02~0.2 ng.L-1。大气降水中的阴离子以SO24-和NO-3为主,其浓度平均值分别为151和145 mo.lL-1;阳离子主要以Ca2+为主,平均浓度达到了123 mo.lL-1,变化范围为3.7~560 mo.lL-1,其次是NH4+和Mg2+,其浓度平均值分别为52.2和20.4 mo.lL-1。通过分析降水中总汞和阴阳离子之间的相互关系,发现总汞和阴离子SO24-具有显著的相关性,与F-有一定的相关性,而与NO-3不具有相关性。由此初步判定,大气降水中的总汞主要来源于燃煤等人为释放源。 | 刘娜 仇广乐 冯新斌 LANDIS Matthew 付学吾 商立海 | 2011 | 生态学杂志2011,30,5: | 5 |
| 4 | Chemical characterization and sources of PM2.5 at 12-h resolution in Guiyang, China显示文摘The increasing emission of primary and gaseous precursors of secondarily formed atmospheric particulate matter due to continuing industrial development and urbanization are leading to an increased public awareness of environmental issues and human health risks in China.As part of a pilot study, 12-h integrated fine fraction particulate matter(PM_(2.5) filter samples were collected to chemically characterize and investigate the sources of ambient particulate matter in Guiyang City, Guizhou Province, southwestern China. Results showed that the 12-h integrated PM_(2.5) concentrations exhibited a daytime average of 51 ± 22 lg m^(-3)(mean ± standard deviation) with a range of 17–128 lg m^(-3) and a nighttime average of55 ± 32 lg m~(^(-3)) with a range of 4–186 lg m^(-3). The 24-h integrated PM_(2.5) concentrations varied from 15 to157 lg m~(^(-3)), with a mean value of 53 ± 25 lg m^(-3), which exceeded the 24-h PM_(2.5) standard of 35 lg m^(-3) set by USEPA, but was below the standard of 75 lg m^(-3), set by China Ministry of Environmental Protection. Energy-dispersive X-ray fluorescence spectrometry(XRF) was applied to determine PM_(2.5) chemical element concentrations. The order of concentrations of heavy metals in PM_(2.5) were iron(Fe) [ zinc(Zn) [ manganese(Mn) [ lead(Pb) [ arsenic(As) [ chromium(Cr). The total concentration of 18 chemical elements was 13 ± 2 lg m^(-3),accounting for 25% in PM_(2.5), which is comparable to other major cities in China, but much higher than cities outside of China. | Longchao Liang Na Liu Matthew S.

| 5 | Comprehensive functional annotation of susceptibility variants identifies genetic heterogeneity between lung adenocarcinoma and squamous cell carcinoma显示文摘Although genome-wide association studies have identified more than eighty genetic variants associated with non-small cell lung cancer(NSCLC)risk,biological mechanisms of these variants remain largely unknown.By integrating a large-scale genotype data of 15581 lung adenocarcinoma(AD)cases,8350 squamous cell carcinoma(SqCC)cases,and 27355 controls,as well as multiple transcriptome and epigenomic databases,we conducted histology-specific meta-analyses and functional annotations of both reported and novel susceptibility variants.We identified 3064 credible risk variants for NSCLC,which were overrepresented in enhancer-like and promoter-like histone modification peaks as well as DNase I hypersensitive sites.Transcription factor enrichment analysis revealed that USF1 was AD-specific while CREB1 was SqCC-specific.Functional annotation and genebased analysis implicated 894 target genes,including 274 specifics for AD and 123 for SqCC,which were overrepresented in somatic driver genes(ER=1.95,P=0.005).Pathway enrichment analysis and Gene-Set Enrichment Analysis revealed that AD genes were primarily involved in immune-related pathways,while SqCC genes were homologous recombination deficiency related.Our results illustrate the molecular basis of both wellstudied and new susceptibility loci of NSCLC,providing not only novel insights into the genetic heterogeneity between AD and SqCC but also a set of plausible gene targets for post-GWAS functional experiments. | Na Qin Yuancheng Li Cheng Wang Meng Zhu Juncheng Dai Tongtong Hong Demetrius Albanes Stephen Lam Adonina Tardon Chu Chen Gary Goodman Stig EBojesen Maria Teresa Landi Mattias Johansson Angela Risch H-Erich Wichmann Heike Bickeboller Gadi Rennert Susanne Arnold Paul Brennan John KField Sanjay Shete Loic Le Marchand Olle Melander Hans Brunnstrom Geoffrey Liu Rayjean JHung Angeline Andrew Lambertus AKiemeney Shan Zienolddiny Kjell Grankvist Mikael Johansson Neil Caporaso Penella Woll Philip Lazarus Matthew BSchabath Melinda CAldrich Victoria LStevens Guangfu Jin David CChristiani Zhibin Hu Christopher IAmos Hongxia Ma Hongbing Shen | 2021 | Frontiers of Medicine2021,15,2: | 3 |
