Monocyclic aromatic hydrocarbons(MAHs)and polycyclic aromatic hydrocarbons(PAHs)are both well known as hazardous air pollutants and also important anthropogenic precursors of tropospheric ozone(O3)and secondary organic aerosols(SOA).In recent years,there have been intensive studies covering MAHs emission from various sources and their behavior under stimulated photochemical *** in-situ measurements of PAHs presence and variations in ambient air are *** we conducted large geometrical scale mobile measurements for 16 aromatic hydrocarbons(AHs,including 7 MAHs and 9 PAHs)in eastern China between October 27 and November 8,*** unique dataset has allowed for some insights in terms of AHs concentration variations,accompanying chemical composition,source contributions and spatial distributions in eastern *** general,AHs showed a clear concentration variability between the south and the north of the Yangtze River Delta(YRD).The concentrations of PAHs were approximately 9%of AHs,but contributed 23%of SOA formation *** apportionment via positive matrix factorization(PMF)model revealed that industrial processes as the largest source(44%)of observed AHs,followed by solvent usage(21%),vehicle exhaust(19%),coal combustion(11%)and coking processes(6%).In the perspective of PAHs sources,coal combustion emissions were identified as the dominating factor of a share of 41%–52%in eastern *** findings complemented the simultaneously monitoring information of PAHs and MAHs in eastern China,revealed the importance of PAHs to SOA formation and highlighted the necessity of formulating strategies to reduce emissions from anthropogenic sources and reduce risks to human health.

As Volatile Organic Compounds(VOCs)are one of the precursors of ozone,their distribution and variable concentrations are highly related to local ozone pollution *** this study,we obtained vertical profiles of VOCs in Shanghai’s Jinshan district on 8 September and 9 September in 2016 to investigate their distribution and impact on local atmospheric oxidation in the near surface *** samples were collected from heights between 50 m and 400 m by summa canisters using an unmanned aerial vehicle(UAV).Concentrations of VOCs(VOCs refers to the 52 species measured in this study)varied minimally below 200 m,and decreased by 21.2%from 100 m to 400 *** concentrations of VOCs above 200 m decreased significantly in comparison to those below 200 *** proportions of alkanes and aromatics increased from 55.2%and 30.5%to 57.3%and 33.0%,***,the proportion of alkenes decreased from 13.2%to 8.4%.Toluene and m/p-xylene were the key species in the formation of SOA and *** component analysis(PCA)revealed that the VOCs measured in this study mainly originated from industrial emissions.

基于近年来我国加强金融行政处罚的背景,文章运用我国160家银行2008-2020年的面板数据,对比了行政处罚对银行个体风险和系统性风险的差异化影响,并深入探讨不同类型和不同受罚对象行政处罚的异质性作用,进一步探究了相应的作用机制。结果表明:第一,行政处罚总次数、对银行机构和责任人的行政处罚均有助于降低银行个体风险和系统性风险;对责任人的行政处罚对银行个体风险和系统性风险的降低作用大于对银行机构的处罚。第二,警告和罚没均可以降低银行个体风险和系统性风险;禁止从业和取消任职有利于降低银行个体风险,但对银行系统性风险的影响不显著;罚没规模有助于降低系统性风险,但对银行个体风险的影响不显著。第三,行政处罚总次数对资本水平低的银行的风险降低作用更大。第四,理财产品在行政处罚与银行风险关系中发挥部分中介效应。文章对于我国完善金融行政处罚和防范金融风险具有重要的现实意义。

琥珀酸是一种高附加值的有机酸,广泛用于食品、化工和农药领域。解脂酵母Yarrowia lipolytica作为新型强健的非传统酵母,近年来逐渐吸引了研究者的注意。前期通过基因敲除琥珀酸脱氢酶基因构建了一株产琥珀酸的重组解脂酵母PGC01003。由于糖酵解和TCA循环流量不协调,PGC01003分泌大量副产物乙酸,限制了琥珀酸产量的进一步提高。为降低乙酸的溢出,实现自然低pH值发酵生产琥珀酸,首先干扰旁路代谢,异源表达来自鼠沙门氏菌的乙酰辅酶A合酶,乙酸的产量下降至4.6 g/L,比对照降低了24.6%。而基因敲除乙酰辅酶A水解酶基因得到的重组菌PGC11505,发酵96 h乙酸分泌量只有0.4 g/L,琥珀酸产量提高到7.0 g/L,琥珀酸的转化率为0.30 g/g,为进一步构建高产琥珀酸的细胞工厂奠定基础。

到客户管理层就职是会计师事务所审计师的一个重要职业选择,但监管机构对审计质量和企业财务报告质量的担忧引发了对此类现象的严格监管。本文基于2002年~2011年我国A股上市公司CFO的变更事件,从审计师的职业谨慎性出发,探讨了CFO审计师经历、"旋转门"现象对上市公司会计稳健性的影响。研究发现:CFO审计师经历能提高会计稳健性;"旋转门"现象并没有削弱公司会计稳健性;相比仅有审计师经历的新聘任CFO,"旋转门"现象下的CFO能更快地融入新公司并发挥作用。
