Abstract
A photochemical trajectory model containing speciated emissions of 124 non-methane volatile organic compounds (VOC), and a comprehensive description of the chemistry of VOC degradation, has been used to simulate the chemical evolution of boundary layer air masses arriving at a field campaign site in the southern UK during a widespread and prolonged photochemical pollution event in August 2003. The simulated concentrations and distributions of organic compounds at the arrival location are compared with observations of a series of hydrocarbons and carbonyl compounds, which were measured using GC-FID and multidimensional GC methods. The comparison of the simulated and observed distributions of 34 emitted hydrocarbons provides some support for the magnitude and applied emissions speciation of anthropogenic hydrocarbons, but is indicative of an under representation of the input of biogenic hydrocarbons, particularly at elevated temperatures. Simulations of the detailed distribution of ca. 1250 carbonyl compounds, formed primarily from the degradation of the 124 emitted VOC, focus on 61 aldehydes, ketones, dicarbonyls, hydroxycarbonyls and aromatic aldehydes which collectively account for ca. 90% of the simulated total molar concentration of carbonyls. The simulated distributions indicate that the photolysis of formaldehyde and alpha-dicarbonyls make major contributions to free radical production for the arrival conditions of five case study trajectories. The simulated concentrations of hydroxycarbonyls demonstrate preferential formation of the 1,4-substituted isomers (compared with 1,2- and 1,3-isomers of the same carbon number), which are formed during the initial oxidation sequence of longer chain alkanes.

Abstract
A commercial automated gas chromatograph with preconcentration on solid adsorbents (AirmoVoc HC1010) was coupled with a mass spectrometer in parallel with the flame ionization detection (FID) system and characterized for its suitability for quasi continuous measurements of atmospheric hydrocarbons (HCs) with a time resolution of 20 min. Of the 50 identified HCs in the range C5-C10, 15 elute in isolated peaks and 20 in groups of two or more HCs. The remaining 15 HCs suffer from coelution by oxygenated and halogenated compounds. Procedures to minimize and quantify the blanks and the memory from the adsorbents are described. Calibration was based on a custom-made diffusion source. The accuracy of this calibration (+/-10%, 2sigma) was verified by analysis of a certified 70-component standard (average deviation: -4.3+/-2%). During a field experiment in Summer 1998, the HC1010 system was compared with a custom-made GC system with cryogenic preconcentration and much better separation properties but lower time resolution. In ambient air, good agreement (2sigma deviation <14% or 10 ppt) was found for HCs and groups of HCs that are free from coelution with oxygenated compounds, whereas large discrepancies (in some cases more than a factor of three) were found for those HCs that coelute with oxygenated compounds, as identified by MS. Analysis of the mass spectra from those peaks via specific target ions showed much better agreement with the FID system of the reference GC within 25%.
