This International Standard specifies the quantitative determination of 16 polycyclic aromatic hydrocarbons (PAH) according to the priority list of the Environmental Protection Agency, USA (EPA, 1982). This International Standard is applicable to all types of soil (field-moist or chemically dried samples), covering a wide range of PAH contamination levels. Under the conditions specified in this International Standard, a lower limit of application of 0,01 mg/kg (expressed as dry matter) can be ensured for each individual PAH.
