10.2          Semi-volatile organics

    10.2.1     Scope and application
This section lists methods for the following classes of non-volatile compounds:
    non-volatile chlorinated hydrocarbons
    PAHs by solvent extraction
    PAHs by supercritical fluid extraction
    organochlorine pesticides (OCPs) and PCBs
    OPPs
    total recoverable hydrocarbons – non-volatile
    phenols
    chlorinated herbicides
    phthalate esters
    dioxins and furans.

Note: Many of these methods use ultrasonic extraction. When this method is used, ensure samples do not overheat; consider putting ice packs into the ultrasonic bath.

This method should not be used for volatile contaminants.
