This part of ISO 16558 specifies a method for the quantitative determination of the total extractablevolatile, the volatile aliphatic, and aromatic fractions of petroleum hydrocarbon content in field moistsoil samples by gas chromatography with mass spectrometric detection. The aromatic fractions aredetermined by the sum of individual aromatic compounds.The sum of the volatile aliphatic (C5 to C10) and aromatic (C6 to C10) fractions can be referred to as“volatile oil”.The results of the test carried out can be used for risk assessment studies related to contaminationswith petroleum hydrocarbons.This part of ISO 16558 provides a method applicable to petroleum hydrocarbon contents from about5 mg/kg soil expressed as dry matter for the whole aliphatic fraction C5 to C10 and about 5 mg/kg soilexpressed as dry matter for the aromatic fraction in the boiling range of C6 to C10.With this method, all hydrocarbons with a boiling range of 36 °C to 184 °C, n-alkanes between C5H12 toC10H22, isoalkanes, cycloalkanes, BTEX, and di- and tri-alkyl benzenes compounds are determined astotal volatile petroleum hydrocarbons C5 to C10. In addition, volatile aliphatic and aromatic fractionsare specified.For the determination of semi-volatile aliphatic and aromatic fractions of petroleum hydrocarbons insoil samples, see ISO/TS 16558-2.NOTE The sub-fractions proposed in this part of ISO 16558 have shown to be suitable for risk assessmentstudies. However, other sub-fractions between C5H12 to C10H22 can be determined in conformity with this partof ISO 16558.On the basis of the peak pattern of the gas chromatogram and of the boiling points of the individualn-alkanes listed in Annex A, the approximate boiling range of the mineral oil and some qualitativeinformation on the composition of the contamination can be achieved.
