| 1 | Trace metals in atmospheric fine particles in one industrial urban city: Spatial variations, sources, and health implications显示文摘Trace metals in PM2.5were measured at one industrial site and one urban site during September, 2010 in Ji'nan, eastern China. Individual aerosol particles and PM2.5samples were collected concurrently at both sites. Mass concentrations of eleven trace metals(i.e., Al, Ti, Cr, Mn, Fe, Ni, Cu, Zn, Sr, Ba, and Pb) and one metalloid(i.e., As) were measured by inductively coupled plasma atomic emission spectroscopy(ICP-AES). The result shows that mass concentrations of PM2.5(130 μg/m3) and trace metals(4.03 μg/m3) at the industrial site were 1.3 times and 1.7 times higher than those at the urban site, respectively, indicating that industrial activities nearby the city can emit trace metals into the surrounding atmosphere. Fe concentrations were the highest among all the measured trace metals at both sites, with concentrations of 1.04 μg/m3at the urban site and 2.41 μg/m3at the industrial site, respectively. In addition, Pb showed the highest enrichment factors at both sites, suggesting the emissions from anthropogenic activities existed around the city. Correlation coefcient analysis and principal component analysis revealed that Cu, Fe, Mn, Pb, and Zn were originated from vehicular trafc and industrial emissions at both sites; As, Cr, and part of Pb from coal-fired power plant; Ba and Ti from natural soil. Based on the transmission electron microscopy analysis, we found that most of the trace metals were internally mixed with secondary sulfate/organic particles. These internally mixed trace metals in the urban air may have diferent toxic abilities compared with externally mixed trace metals. | Shengzhen Zhou Qi Yuan Weijun Li Yaling Lu Yangmei Zhang Wenxing Wang | 2014 | Journal of Environmental Sciences2014，26，1： | 23 |
| 2 | Indian hedgehog mutations causing brachydactyly type A1 impair Hedgehog signal transduction at multiple levels显示文摘Brachydactyly 打 A1 (BDA1 ) ,第一在人记录了孟德尔的正染色体的主导的混乱,被弄短或中间的指骨的缺席描绘。在印度刺猬(IHH ) 基因的异质接合的错误感觉变化作为 BDA1 的一个原因被识别了;然而,这些变化的生物化学的后果是不清楚的。在这份报纸,我们在印度刺猬(IhhN ) 的 N 终端碎片分析了三个 BDA1 变化(E95K, D100E,和 E131K ) 。结构的分析证明 E95K 变化在一条钙绑定沟把一个否定地控告的区域改变到一个断然控告的区域,并且 D100E 变化改变本地第三级的结构。而且,我们证明 E95K 和 D100E 变化导致了一温度敏感并且 IhhN 的钙依赖者不稳定性,它可能经由 lysosome 贡献变异的蛋白质的提高的细胞内部的降级。尤其是,所有三个变化影响了对受体 Patched1 (PTC1 ) 有约束力的 Hh,减少它的能力导致细胞的区别。我们建议这些是引起 BDA1 的变化的普通特征,影响 Hh 第三级的结构,细胞内部的命运,到受体 / 搭挡的绑定,和到细胞外的部件的绑定。这些特征的联合改变发信号的能力和范围,但是影响是可能的是变量和变化依赖者。在发信号的范围的潜在的变化被和 heparan 硫酸盐的一个提高的相互作用与 E95K 变化,然而并非 E131K 变化为 IHH 描绘。一起拿,我们的结果建议这些 IHH 变化影响在多重层次,引起的反常骨头发展和反常的位形成发信号的 Hh。 | Gang Ma Jiang Yu Yue Xiao Danny Chan Bo Gao Jianxin Hu Yongxing He Shengzhen Guo Jian Zhou Lingling Zhang Linghan Gao Wenjuan Zhang Yan Kang Kathryn SE Cheah Guoyin Feng Xizhi Guo Yujiong Wang Cong-zhao Zhou Lin He | 2011 | Cell Research2011，21，9： | 6 |

| 6 | Fluorescence enhancement and cytotoxicity reduction of bis-viologen biphenyl by complexation of cucurbit[7]uril显示文摘The effect of cucurbit[7]uril(CB[7]) on fluorescence properties and biocompatibility of the bis-viologen biphenyl molecule(BPV22+) was investigated by using 1 H NMR spectroscopy,fluorescence emission titration,and in vitro cytotoxicity experiments.CB[7] can be combined with BPV22+ in a stoichiometric ratio of 1:1 and 2:1.After the formation of host-guest complex,the fluorescence emission intensity of BPV22+ increased significantly,and the emission spectrum blue shifted.Meanwhile,the host-guest complexes showed better biocompatibility than BPV22+ in cell cytotoxicity studies.Results of this paper lay a foundation for the development of host-guest type of fluo rescent probes,biological imaging and so forth. | Jing Zhou Shengzhen Hou Jin Zhang Yanru Chen Hao Chen Yebang Tan | 2021 | Chinese Chemical Letters2021，32，2： | 1 |
| 7 | Atmospheric HONO formation during and after the Spring Festival holidays in a coastal city of China显示文摘Nitrous acid(HONO)is an important source of hydrogen oxides(HOx),which affects air quality,the atmospheric oxidation capacity,and human health.Here,we present ambient measurements of the HONO concentrations in Zhuhai,a coastal city in Southern China,from February 7 to March 15,2021.The campaign was classified into two periods during(P1)and after(P2)the Spring Festival holidays.The average HONO mixing ratio during P2(1.19±0.85 ppbv)was much higher than that during P1(0.24±0.18 ppbv),likely due to the contribution of homogeneous HONO formation.During nighttime,the heterogeneous conversion rate during P2(0.0089/hr)was considerably higher than that during P1(0.0057/hr),suggesting a higher heterogeneous NO_(2) conversion potential.However,the heterogeneous NO_(2) conversion was the dominant way during P1 with a high percentage of 88%,while comparable ratios of heterogeneous and homogeneous formation were found(54%vs.46%)during P2,indicating that the homogeneous formation was also important during P2.During daytime,homogeneous reaction was the major known pathway,with a contribution of 16%during P1 and 27%during P2,leaving large unknown HONO sources which reasonably correlated with the photo-enhanced NO_(2) conversion.Two case scenarios were additionally explored,showing that there might be a primary emission source during one scenario(February 17-18)and vehicle emissions might be the major unknown HONO source for another scenario(March 3–5).The results suggest that large unknown daytime sources still exist which need more future ambient and laboratory studies. | Xue Ni Cuizhi Sun Yongyun Zhang Baoling Liang Shengzhen Zhou Guangdong Lan Jun Zhao | 2023 | Journal of Environmental Sciences2023，，5： | 0 |
| 8 | Estimation of Economic and Ecological Value of Raising Sheep in Pastoral Area显示文摘Tibetan sheep is a unique breed of livestock in Alpine pastoral areas,which is one of the main economic pillars of animal husbandry in pastoral areas,in order to analyze and compare the estimated the economic and ecological benefits of Tibetan sheep under different feeding modes,this paper used a simplified model from multiple angles of animal production,economics and Ecology,The results show that:(i)Under the traditional grazing condition,the annual income of raising one ewe is only 23.4 yuan;(ii)Under the high-efficiency breeding mode,the average income of ewes bred by high-efficiency technology was 168 yuan/(head·year),which was 7 times higher than that of ewes under traditional grazing;each lamb could produce an indirect economic benefit of 500 yuan;(iii)The ecosystem service value affected by each Tibetan sheep through grassland was above 150000 yuan. | Zenghai LUO Shengzhen HOU Zhiyou WANG Yuchun XIN Huakun ZHOU Guiying YUAN | 2020 | Asian Agricultural Research2020，12，6： | 0 |
| 9 | 同时发生的台风和海洋富营养化是湿沉降中有机氮的可能来源之一吗?显示文摘研究目的:大气有机氮沉降的通量始终与排放的量不吻合,因此其缺失来源值得我们探讨。创新要点:研究发现同时发生台风与海洋富营养化情况下带来的鼎湖山站有机氮湿沉降占到了总有机氮湿沉降的1/3。研究方法:站点湿沉降采样+化学组分分析+后向轨迹模式。重要结论:在海洋富营养化的情况下,台风可能会将海洋表面的含氮组分带入大陆,成为大气有机氮沉降通量的重要组成。 | CHANG Ming CHEN Weihua DENG Sixin WANG Xuemei ZHOU Shengzhen | 2020 | Atmospheric and Oceanic Science Letters2020，13，3： | 0 |
| 10 | 珠三角秋季硝酸盐气溶胶致霾污染的区域性特征显示文摘为研究珠三角地区大气霾污染特征和形成机制,于2014年秋季在区域内三个典型观测站同步开展了细颗粒物外场观测。结果表明,三个站点大气细颗粒物及其化学组分质量浓度的时间变化趋势高度一致,呈现出区域性特征。结合气象因素分析,发现珠三角区域霾污染的形成受到中尺度的静态天气形势的影响。随着霾污染过程的发展,细颗粒物中硝酸盐的比例显著增加,移动源的贡献较大。结合后向气流轨迹和卫星火点分布,证实区域内的生物质燃烧会加剧大气霾污染的强度。为进一步改善珠三角的空气质量,建议在区域尺度上实施联防联控的减排方案。 | GUO Junchen ZHOU Shengzhen SUN Xi HUANG Minjuan DONG Hanying CHANG Ming FAN Qi FAN Shaojia WANG Xuemei | 2020 | Atmospheric and Oceanic Science Letters2020，13，3： | 0 |
