Method for detecting particulate matters in atmosphere and polycyclic aromatic hydrocarbons and derivatives thereof in gas phase

The invention relates to the technical field of pretreatment of polycyclic aromatic hydrocarbons and derivatives thereof, in particular to a method for detecting particulate matters in atmosphere and polycyclic aromatic hydrocarbons and derivatives thereof in a gas phase, and the method comprises the following steps: respectively collecting an atmospheric particulate matter sample and a gas phase sample by using a quartz filter membrane or polyurethane foam; the method comprises the following steps: dividing a sample into fragments, putting the fragments into an extraction pool, taking an organic mixed solvent as an extraction solution, and extracting organic substances in the sample into the extraction solution; separating and purifying the extract liquor by using an extraction column, eluting the extract liquor by using an organic mixed solution, and collecting eluent; and carrying out nitrogen blowing on the eluent, fixing the volume by using an organic solvent, and analyzing by using a triple quadrupole G
