Description

BS PD CEN ISO/TS 16558-2:2015 specifies a method for the quantitative determination of the total extractablesemi-volatile, aliphatic, and aromatic fractions of petroleum hydrocarbon content in field moist soilsamples by gas chromatography.

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 about100 mg/kg soil expressed as dry matter for the whole aliphatic fraction C10 to C40, as well as thearomatic fraction C10 to C40. For sub-fractions, lower limits of determination can be reached.If lower detection limits are required, large volume injection can be used or concentration of the finalextract can be carried out.

NOTE 1 Low concentrations of aliphatic and aromatic compounds can be found in natural uncontaminatedorganic rich soils like peat soils.

With this method, all hydrocarbons with a boiling range of 174 °C to 525 °C, n-alkanes between C10H22to C40H82, isoalkanes, cycloalkanes, alkyl benzenes, and alkyl naphthalenes and polycyclic aromaticcompounds are determined as total extractable semi-volatile petroleum hydrocarbons C10 to C40;besides that, semi-volatile aliphatic and aromatic fractions are specified.

For the determination of volatile aliphatic and aromatic fractions of petroleum hydrocarbons in soilsamples, see ISO 16558-1.

NOTE 2 The sub-fractions proposed in this part of ISO 16558 have shown to be suitable for risk assessmentstudies. However, other sub-fractions between C10H22 to C40H82 can also be determined in conformity with thispart of 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 B, the approximate boiling range of the mineral oil and some qualitativeinformation on the composition of the contamination can be achieved.
