The isolation of some polynuclear aromatic hydrocarbons from aqueous samples by means of reversed-phase concentrator columns

Abstract The results for some polynuclear aromatic hydrocarbons (PAH) in canal water and rain water differ depending on whether the PAH are concentrated directly on Sep- Pak C-18 cartridges or concentrated after filtration with further analysis of the particulate matter. For canal waters, higher total PAH concentrations are obtained when the suspended material is also analyzed.
