The work of preparing
21、International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaiso
22、n with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Direct
23、ives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some
24、 of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarat

29、out analysis for petroleum hydrocarbons in soils and soil-like materials including sediments. It provides guidance for the appropriate use of the analytical results in risks assessment. This part of ISO 16558 specifies methods for the quantitative determination of the appropriate fractions of alipha
30、tic and aromatic compounds. The methods described are based on existing standards mineral oil (ISO 16703) and volatile hydrocarbons (ISO 22155).The general use and relation between the two different parts of this International Standard is given in Figure 1.KeyaFlorisilbclean-up: Only to be applied i
31、n case the test according to ISO 16703 is carried out. If the aliphatic and aromatic fractions have to be analysed, florisil clean-up should not be carried out. Florisil is a trade name for a prepared diatomaceous substance mainly consisting of anhydrous magnesium silicate.bFlorisil is an example of
32、 a suitable product available commercially.

34、ifies a method for the quantitative determination of the total extractable volatile, the volatile aliphatic, and aromatic fractions of petroleum hydrocarbon content in field moist soil samples by gas chromatography with mass spectrometric detection. The aromatic fractions are determined by the sum o
35、f individual aromatic compounds.The sum of the volatile aliphatic (C5to C10) and aromatic (C6to 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 contaminations with petroleum hydrocarbons.This part of ISO 16558
36、 provides a method applicable to petroleum hydrocarbon contents from about 5 mg/kg soil expressed as dry matter for the whole aliphatic fraction C5to C10and about 5 mg/kg soil expressed as dry matter for the aromatic fraction in the boiling range of C6to C10.With this method, all hydrocarbons with a
37、 boiling range of 36 C to 184 C, n-alkanes between C5H12to C10H22, isoalkanes, cycloalkanes, BTEX, and di- and tri-alkyl benzenes compounds are determined as total volatile petroleum hydrocarbons C5to C10. In addition, volatile aliphatic and aromatic fractions are specified.For the determination of
38、semi-volatile aliphatic and aromatic fractions of petroleum hydrocarbons in soil samples, see ISO/TS 16558-2.NOTE The sub-fractions proposed in this part of ISO 16558 have shown to be suitable for risk assessment studies. However, other sub-fractions between C5H12to C10H22can be determined in confor
39、mity with this part of ISO 16558.On the basis of the peak pattern of the gas chromatogram and of the boiling points of the individual n-alkanes listed in Annex A, the approximate boiling range of the mineral oil and some qualitative information on the composition of the contamination can be achieved
