Concentrations of selected volatile organic compounds at kerbside and background sites in central London

Fluxes and concentrations of volatile organic compounds above central London, UK

Concentrations and fluxes of eight volatile organic compounds (VOCs) were measured during October 2006 from a high telecom tower above central London, as part of the CityFlux contribution to the REPARTEE I campaign. A continuous flow disjunct eddy covariance technique with analysis by proton transfer reaction mass spectrometry was used. Daily averaged VOC mixing ratios were within the range 1–1...

Interpretation of Particulate Elemental and Organic Carbon Concentrations at Rural, Urban and Kerbside Sites

synthesis of 3-aryl-2h-benzo[b]-1,4-oxazines in [omim]bf4 and reduction of organic compounds in methylimidazolium formate

در این پروژه ترکیبات 3-آریل-2h-بنزو[b]-4،1-اکسازین ها از مواد اولیه تجاری مشتقات دو آمینو فنول و ?-هالو کتون های آروماتیک در مایع یونی 1-اکتیل-3-متیل ایمیدازولیوم تترا فلورو بورات([omim]bf4) سنتز شده است. این واکنش توسط باز پتاسیم کربنات محلول از طریق o-آلکیلاسیون و سپس یک واکنش آمیداسیون درون مولکولی خود بخود در مدت زمان کوتاه انجام می شود. ترکیبات 4،1-بنزوکسازین به این روش با بهره خوب تا آلی ...

selected organic compounds in fine particulatematter at the regional background, urban background and urbantraffic points in silesia (poland)

suspended particles with aerodynamic diameters not greater than 2.5 μm (pm2.5) were sampledat the urban background, regional background and urban traffic points in southern poland. in total, 120 sampleswere collected between 2nd august 2009 and 27th december 2010. 16 polycyclic aromatic hydrocarbons (pahs)and organic carbon (oc) were determined in each sample. the samples were collected with a ...
