The focus of polynuclear aromatic hydrocarbons (PAH) in soil is set by initial extracting the PAHs with methylene chloride. The extract is diluted, if important, as well as the PAHs divided by HPLC utilizing a UV/Vis or fluorescence detector. Calibration is accomplished applying one or more exterior requirements.
