%X In order to obtain the chemical speciation and diurnal pattern of ambient volatile organic compounds(VOCs),a continuous half hour measurement was performed on top of a 55 meter tall building in Guangzhou in July,2006,using a set of automated gas chromatography instruments.The various VOC species showed different diurnal variations.Alkanes and alkenes had two peaks in the morning and evening,corresponding to the local traffic rush hours,indicating these species were mainly due to vehicular emissions.The morn...
