Method for the Validation of PAHs in Soil and Sediment Samples Using Pressurized Liquid Extraction and Automated Cleanup

摘要

PAHs are a group of organic compounds consisting of two or more benzene rings and are often the byproduct of petroleum combustion. Due to their carcinogenic characteristics at relatively low concentrations, they are of particular environmental concern. Seven PAHs have been classified by the US EPA as probable human carcinogens and their toxic characteristics and persistent nature place them among the most extensively monitored organic contaminants.
