Webinitial sampling are available, the SVOCs reported by the lab can be narrowed to a specific list of parameters based on the initial findings. PAHs: Polycyclic aromatic hydrocarbons (PAHs) refer to a large class of organic compounds that contain only carbon and hydrogen, and are comprised of two or more fused aromatic rings. PAHs are WebThere are two common methods for the determination of PAHs in environmental samples. The first is high performance liquid chromatography (HPLC) using EPA methods 610 or 8310. In this method, a combination of UV and fluorescence detection is used to determine 16 common PAHs. This method can be somewhat problematic due to matrix interferences.
