The method described by the invention is to provide the technical support for the environmental management department to formulate the countermeasure to regional polycyclic aromatic hydrocarbon pollution, enabling the relevant department to apply complete source analysis method quickly to identify the pollution source and carry on the effective pollution prevention and control when such pollution problem occurs.1/2 32 n 31 .V; 33 2 4 11 * -.4 2 FIG, 1
