Annotation of standard text ČSN P CEN ISO/TS 16558-2 (836704):
P CEN/TS 16558-2 This part of ISO 16558 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 to 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 C10 to C40, as well as the aromatic 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 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 peat soils. With this method, all hydrocarbons with a boiling range of 174 °C to 525 °C, n-alkanes between C10H22 to C40H82, isoalkanes, cycloalkanes, alkyl benzenes, and alkyl naphthalenes and polycyclic aromatic compounds 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 soil samples, see ISO 16558 1. NOTE 2: The sub-fractions proposed in this part of ISO 16558 have shown to be suitable for risk assessment studies. However, other sub-fractions between C10H22 to C40H82 can 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 boiling range of the mineral oil and some qualitative information on the composition of the contamination can be achieved
