Detection and Site Characterization
Determining the presence of dioxins at a site can be a matter of simple screening. However, determining which dioxins are present involves speciation testing. This section lists well-established, standard methods commonly used for detecting, measuring, and/or monitoring dioxins particularly EPA-approved methods used for environmental samples.
