The results of the test carried out can be used for risk assessment studies related to contaminations with petroleum hydrocarbons.
ISO/TS 16558-2:2015 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.
