BS EN 15527:2008EN 15527:2008 (E) 4 Introduction Polynuclear aromatic hydrocarbons (PAH) are ubiquitous because of the fact that they are released in appreciable

19、quantities every year into the environment through the combustion of organic materials such as coal, fuel oils, petrol, wood, refuse and plant materials. Since some of these PAH compounds are carcinogenic or mutagenic, their presence in the environment (air, water, soil, sediment and waste) are regu

20、larly monitored and controlled. At present, the determination of PAH is carried out in these matrices in most of the routine laboratories following the preceding steps for sampling, pre-treatment, extraction, clean-up by measurement of specific PAH by means of gas chromatography in combination with

21、mass spectrometric detection(GC-MS) or by HPLC in combination with UV-DAD- or Fluorescence-detection (HPLC-UV-DAD/FLD). However, the different matrices covered in this standard may contain a lot of contaminants. For this reason, the GC-MS method seems to be most appropriate for waste analysis. BS EN

22、 15527:2008EN 15527:2008 (E) 5 1 Scope This European Standard specifies the quantitative determination of 16 polynuclear aromatic hydrocarbons (PAH) according to the priority list of the Environmental Protection Agency (EPA, 1982). This European Standard is applicable for wastes such as contaminated

23、 soil, sludge and rubble, bitumen or waste containing bitumen. This European Standard describes a gas chromatographic method with mass spectrometric detection (GC-MS). Under the conditions specified in this document, a typical lower limit of application of 0,1 mg/kg for each individual PAH can be ac

24、hieved. NOTE 1 This method may be applied to the analysis of other PAH compounds not specified in the scope provided its applicability has been proven by proper in-house validation experiments. NOTE 2 For some materials, e. g. bitumen, the lower limit of application of 0,1 mg/kg cannot be achieved d

25、ue to interferences. NOTE 3 Under certain circumstances the method may be applicable to PAH concentrations lower than 0,1 mg/kg but it is in the responsibility of the laboratory to provide proper validation data for such low concentrations. 2 Normative references The following referenced documents a

If appropriate, the obtained extract is purified by adsorption column chromatography. The extract is analysed by gas chromatography with mass spectrome
