| 1 | Pollution characteristics, sources and lung cancer risk of atmospheric polycyclic aromatic hydrocarbons in a new urban district of Nanjing, China显示文摘This paper focused on the pollution characteristics,sources and lung cancer risk of atmospheric polycyclic aromatic hydrocarbons(PAHs) in a new urban district of Nanjing,China.Gaseous and aerosol PM_(2.5)(particulate matter with aerodynamic diameter smaller than2.5 urn) samples were collected in spring of 2015.Sixteen PAHs were extracted and analyzed after sampling.Firstly,arithmetic mean concentrations of PAHs and BaP_(eq)(benzo[a]pyrene equivalent) were calculated.The mean concentrations of PAHs were 29.26±14.13,18.14±5.37 and 48.47±16.03 ng/m^3 in gas phase,particle phase and both phases,respectively.The mean concentrations of BaP_(eq) were 0.87±0.51,2.71±2.17 and 4.06±2.31 ng/m^3 in gas phase,particle phase and both phases,respectively.Secondly,diagnostic ratios and principal component analysis were adopted to identify the sources of PAHs and the outcomes were the same:traffic exhaust was the predominant source followed by fuel combustion and industrial process.Finally,incremental lung cancer risk(ILCR) induced by whole year inhalation exposure to PAHs for population groups of different age and gender were estimated based on a Monte Carlo simulation.ILCR values caused by particle phase PAHs were greater than those caused by gas phase PAHs.ILCR values for adults were greater than those for other age groups.ILCR values caused by total(gas + particle) PAHs for diverse groups were all greater than the significant level(10~6),indicating high potential lung cancer risk.Sensitivity analysis results showed that cancer slope factor for BaP inhalation exposure and BaP_(eq) concentration had greater impact than body weight and inhalation rate on the ILCR. | Tao Wang Zhonghuan Xia Minmin Wu Qianqian Zhang Shiqi Sun Jing Yin Yanchi Zhou Hao Yang | 2017 | Journal of Environmental Sciences2017，29，5： | 7 |

| 8 | Electro-oxidation cross-coupling of primary and secondary alcohols by constructing intermediate-enriched micro-environment显示文摘Electrocatalytic dehydrogenative cross-coupling of various alcohols in aqueous electrolytes functionalizes alcohols to form structurally diverse long-carbon-chain chemicals.However,it remains challenging to achieve the high selectivity because of the high reactivity of involved carbonyl intermediates and different oxidation rates for the alcohols.Herein,the synthesis ofα,β-unsaturated ketones from alcohols was realized by the electro-oxidation cross-coupling in aqueous solutions by a“salting-out”strategy to engineer the micro-environment at electrocatalytic reaction interfaces.Theoretical calculations and electrochemical measurements demonstrated that concentrated local intermediates could inhibit the over-oxidation of alcohols and accelerate the coupling reaction kinetics between the intermediates.This strategy can couple primary and secondary alcohols to formα,β-unsaturated carbonyl compounds with a selectivity of 87% and be easily scaled up to gram scales.This study provides an attractive strategy for broadening the diversity of organic products in electrocatalysis. | Leitao Xu Cairong Wang Yelin Yao Wei Chen Zhonghuan Zhu Jingcheng Wu Ming Yang Yandong Wu Shuangyin Wang Yuqin Zou | 2023 | Science China Chemistry2023，66，8： | 0 |
