The work of preparing International Standards is
22、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 liaison with ISO, also take part
23、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 Directives, Part 1. In particula
24、r 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 of the elements of this
25、document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

30、s 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 aliphatic and aro
31、matic compounds. The methods described in this part of ISO 16558 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 ISO 16558 are given in Figure 1. Key a Florisil bclean-up: Only to be applie

35、58 specifies a method for the quantitative determination of the total extractable semi-volatile, aliphatic, and aromatic fractions of petroleum hydrocarbon content in field moist soil samples by gas chromatography. The results of the test carried out can be used for risk assessment studies related t
36、o contaminations with petroleum hydrocarbons. This part of ISO 16558 provides a method applicable to petroleum hydrocarbon contents from about 100 mg/kg soil expressed as dry matter for the whole aliphatic fraction C 10to C 40,as well as the aromatic fraction C 10to C 40 . For sub-fractions, lower l
37、imits of determination can be reached. If lower detection limits are required, large volume injection can be used or concentration of the final extract can be carried out. NOTE 1 Low concentrations of aliphatic and aromatic compounds can be found in natural uncontaminated organic rich soils like pea
38、t soils. With this method, all hydrocarbons with a boiling range of 174 C to 525 C, n-alkanes between C 10 H 22to C 40 H 82 , isoalkanes, cycloalkanes, alkyl benzenes, and alkyl naphthalenes and polycyclic aromatic compounds are determined as total extractable semi-volatile petroleum hydrocarbons C
39、10to C 40 ; besides that, semi-volatile aliphatic and aromatic fractions are specified. For the determination of volatile aliphatic and aromatic fractions of petroleum hydrocarbons in soil samples, see ISO 16558-1. NOTE 2 The sub-fractions proposed in this part of ISO 16558 have shown to be suitable
40、 for risk assessment studies. However, other sub-fractions between C 10 H 22to C 40 H 82can also be determined in conformity 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 B, the approximate
41、boiling range of the mineral oil and some qualitative information on the composition of the contamination can be achieved. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
