| 4 | Simultaneous monitoring of PCB profiles in the urban air of Dalian,China with active and passive samplings显示文摘The concentration of polychlorinated biphenyls (PCBs) in the urban air of Dalian, China was monitored from November 2009 to October 2010 with active high-volume sampler and semipermeable membrane device (SPMD) passive sampler. The concentration of PCBs (particle + gas) ( ∑ PCBs) ranged from 18.6 to 91.0 pg/m 3 , with an average of 50.9 pg/m 3 , and the most abundant dioxin-like PCB (DL-PCBs) was PCB118. The WHO-TEQ values of DL-PCBs were 3.6-22.1 fg/m3 , with an average of 8.5 fg/m 3 , and PCB126 was the maximum contributor to ∑ TEQ. There was a much larger amount of PCBs in the gas phase than in the particulate phase. The dominant PCB components were lower and middle molecular weight PCBs. With increasing chlorination level, the concentration of the PCB congeners in the air decreased. The gas-particulate partitioning of PCBs was different for the four seasons. The gas- particulate partitioning coefficients (logK p ) vs. subcooled liquid vapor pressures (logP L 0 ) of PCBs had reasonable correlations for different sampling sites and seasons. The absorption mechanism contributed more to the gas-particulate partitioning process than adsorption. Correlation analysis of meteorological parameters with the concentration of PCBs was conducted using SPSS packages. The ambient temperature and atmospheric pressure were important factors influencing the concentration of PCBs in the air. The distribution pattern of the congeners of PCBs and the dominant contributors to DL-PCBs and TEQ in active samples and SPMDs passive samples were similar. SPMD mainly sequestrated gas phase PCBs. | Qian Xu Xiuhua Zhu Bernhard Henkelmann Karl-Werner Schramm Jiping Chen Yuwen Ni Wei Wang Gerd Pfister Jun Mu Songtao Qin Yan Li | 2013 | Journal of Environmental Sciences2013,25,1: | 8 |
| 5 | QSPR study about sampling rates of semipermeable membrane devices for monitoring of organochlorine pesticides in Alps air显示文摘Organochlorine pesticides (OCP) were monitored at the Weissfluhjoch site (Switzerland) and the top of Mt. Sonnblick (Austria) with a low volume active air sampler and semipermeable membrane devices (SPMD). The air sampling rates (Rair) of the SPMD for OCP were calculated. Statistical tests showed that there was no significant difference between Rair at the two different sampling sites. Quantitative structure-property relationship (QSPR) models of the Rair of the SPMD were developed for OCP using partial least square (PLS) regression. Quantum chemical descriptors computed by the semi-empirical PM6 method were used as predictor variables. The cumulative variance of the dependent variable explained by the PLS components and determined by cross-validation (Q2cum) was >0.818 for each optimal model. This indicates that the model has good predictive ability and robustness. The Rair of the SPMD for OCP is related to the total energy, the van der Waals area and the total dipole moment of the OCP molecules. The main factors governing Rair values of OCP are intermolecular interactions and the energy required for cavity-formation in dissolution of OCP into triolein of the SPMD. The linear correlation coefficient between predicted and experimental values were all >0.921. | ZHU XiuHua DING GuangHui LEVY Walkiria JAKOBI Gert OFFENTHALER Ivo MOCHE Wolfang WEISS Peter SCHRAMM Karl-Werner | 2011 | Chinese Science Bulletin2011,56,18: | 5 |
| 6 | 半透膜仪采集空气中多氯联苯采样速度与其结构和性质定量构效关系研究(英文)显示文摘根据MOPAC2009软件包中PM6算法得到的分子描述符研究半透膜仪(SPMDs)采集大气中多氯联苯(PCBs)采样速度(R_(air))的定量构效关系(QSPR)模型,并分析影响R_(air)的关键因素。以半经验PM6算法得到的分子量子化学描述符作为预测变量,采用偏最小二乘算法(PLS)构建了R_(air)的QSPR模型。根据交叉验证,所得到的最佳模型中PLS成分解释的因变量的累积变异(Q^2_(cum))为0.683,这表明该模型具有良好的预测能力和稳健性。通过外部验证和将实验测得的R_(air)与预测得到的R_(air)进行比较,对所构建模型的稳定性和可靠性进行了验证,结果表明无论是训练组还是预测组,其预测值与实测值间均具有较好的线性关系,线性相关系数均大于0.8376。对PCBs采样速度R_(air)的主要影响因素为PCBs与SPMDs中甘油三油酸酯分子间的相互作用大小和为将PCBs溶解在甘油三油酸酯中形成洞穴所需能量要求。 | 朱秀华 丁光辉 Walkiria Levy Karl-Werner Schramm 王炜 穆军 | 2011 | 计算机与应用化学2011,28,1: | 4 |
| 7 | 衡量适当产前保健的成本和效益显示文摘许多研究显示接受适当产前保健,能改善妊娠后果,特别是减少低出生体重儿发生的风险。因为低体重儿的医疗费用是正常体重儿的几倍,人们不难预料,获得适当产前保健产妇的新生儿,其医疗费用将较那些不适当产前保健的新生儿为低。这项报告研究了新生儿和产妇产后保健的医疗补助费用的降低,是不是超过医疗困难补助制度整体保健费用的增加。适当产前保健的产前保健费用比不适当的产前保健高233美元。适当产前保健妊娠在产后60天内,新生儿和产后保健费用要低347美元。使得产前保健多用1美元就能节省1.49美元。 | Schramm WF 封禹 | 1993 | 国外医学(卫生经济分册)1993,10,4: | 3 |

| 11 | Honeybees prefer novel insect-pollinated flower shapes over bird-pollinated flower shapes显示文摘Plant-pollinator in teractio ns have a fundame ntal in fluence on flower evolution. Flower color signals are frequently tuned to the visual capabilities of important pollinators such as either bees or birds, but far less is known about whether flower shape in fluences the choices of pollinators. We tested European honeybee Apis mellifera pref ere nces using novel achromatic (gray-scale) images of 12 insect-pollinated and 12 bird-pollinated native Australian flowers in Germany;thus, avoiding in flue nces of color, odor, or prior experie nee. In depende nt bees were tested with a number of parameterized images specifically desig ned to assess pref ere nces for size, shape, brightness, or the number of flower-like shapes prese nt in an image. We show that honeybees have a pref ere nee for visiti ng images of in sect-polli nated flowers and such a pref ere nee is most-likely mediated by holistic in formati on rather than by in dividual image parameters. Our results in dicate an giosperms have evolved flower shapes which in fluence the choice behavior of importa nt pollinators, and thus suggest spatial achromatic flower properties are an important part of visual signaling for plantpollinator in teractions. | Scarlett R.

| 15 | Effects of submergence in water on seed germination and vigor of the Copaifera lucens(Fabaceae) seedlings显示文摘We analyzed the tolerance of Copaifera lucens seeds to submersion in water to assess the use of this species for direct seeding in riparian forest restoration programs. Seeds were submerged in water for 2, 4, 8, 16 and 32 days or not submerged(control = 0 days of submergence). For the control and at the end of each period of submersion, germination and seedling vigor tests were carried out. For germination tests, seeds were sown in plastic pots containing sand and kept in laboratory conditions. The percentage of seed germination, the germination rate and the average germination time were analyzed. For seedlings, total biomass, leaf area, leaf mass per area and leaf area ratio were analyzed. Submersion time drastically affected the dissolved oxygen content and seed germination. Between 4 and 8 days of submersion there was a decrease from 83.8% to 15.6% in the germination percentage. No seed germination occurred after 16 days of submersion. Although there was a significant decrease in the percentage of seed germination between 4 and 8 days of submersion, seedling vigor was not affected. Seeds of this species were partially tolerant to submersion in water, suggesting that C. lucens is a promising species for direct seeding in riparian forest restoration projects. | Daniela Baldez Vidal Isis Leite Andrade Eusinia Louzada Pereira Andrade Marcelo Schramm Mielke | 2014 | Journal of Forestry Research2014,25,4: | 2 |
