Part 4: Taxonomy

Water quality. Determination of polycyclic aromatic hydrocarbons (PAH) - Determination of six PAH by high-performance liquid chromatography with fluorescence detection after liquid-liquid extraction Ingestion-build-183098 inflammatory bowel disease1 Scope This part of ISO 7981 specifies the determination of six selected PAH in drinking, mineral and table waters and ground and surface waters in mass concentrations above 0,005 g l, by high performance liquid chromatography with fluorescence detection after liquid liquid extraction. The six PAH are: fluoranthene, benzo[b]fluoranthene, benzo[a]pyrene, benzo[k]fluoranthene, indeno[1,2,3 cd]pyrene, and benzo[ghi]perylene (see Table 1). With some
