Abstract:

The C 5-C 15 hydrocarbon compounds have been studied in surficial sediments from the Bransfield strait,Antarctica.They include alkane,iso alkane,cyclohexane,aromatic and their substituted compounds.All samples contain large amount of aromatic compounds as benzene,toluene,xylene and trimethyl benzene.The toluene is the dominant component.The ratio between benzene and hexane is 0.47-1.26. Differentation of alkane,iso alkane,cyclohexane and aromatic compounds was achieved by using R type and Q type factor analysis,as well as principal factor analysis.By these analysis,the three factor of site G 27 have the extreme values.
