International Standards are drafted in accordance with the rules given in the ISO/lEC Directives, Part 2 The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote Attention is drawn to the possibility that some of the elements of this document may be the subject of patent ISO 18287 was prepared by Technical Committee ISO/TC 190, Soil quality, Subcommittee SC 3, Chemical methodsandsoilcharacteristics. iv @ISO 2006-Allrights reserved ISO18287:2006(E) Introduction This International Standard is principally based on the extraction method described in IsO 13877. It is PAH pollution levels of soils. Two alternativeextraction methods,A andB,are describedinthisInternational Standard Method A (two-step method): Extraction of the field-moist soil sample with acetone and petroleum ether, followed by the removal of acetone by washing the extract with water as prescribed in IsO 13877. Method B (one-step method or on-line method): Extraction of the field-moist soil sample with a mixture of samples with a high content of organic matrix. polluted soils @ ISO 2006 All rights reserved INTERNATIONALSTANDARD ISO 18287:2006(E) Soil quality Determination of polycyclic aromatic hydrocarbons (PAH) Gas chromatographic method with mass spectrometric detection (GC-MS) SAFETY PRECAUTIONSCertain PAH are highly carcinogenic and must be handled with extreme care.Contact of solid materials,
