Scope: Scope of This Guide This document was designed to be an introductory guide to understanding and assessing polycyclic aromatic hydrocarbons (PAHs) in the aquatic environment (water and sediments). The American Petroleum Institute (API) commissioned this guide primarily for refinery personnel and home office environmental staff who may have to address PAH issues. In addition@ this guide may also be useful to staff in regulatory agencies that work with PAHs in wastewater discharge permits@ waste load allocations (TMDLs)@ and sediment investigation and remediation. The guide provides an overview on the chemistry@ fate@ and sources of PAHs in the environment@ and the regulatory implications. The guide also includes descriptions of the different sources of PAHs (petrogenic@ pyrogenic@ diagenic@ biogenic) and techniques for differentiating these sources through their characteristic fingerprints@ including straightforward ways to help identify or rule out potential sources.
