Claim 2:
3. The quantitative source apportionment method based on nontarget HRMS data of pollution source and pollution receptor as claimed in claim 2, wherein step 2 comprises:
for the non-polar organic compounds, performing the nontarget analysis by using a gas chromatography (GC)-quadrupole time-of-flight HRMS with an electron ionization source or a chemical ionization source or a GC-Orbitrap HRMS with the electron ionization source or the chemical ionization source; and
for the polar organic compounds and water-soluble compounds, performing the nontarget analysis by using an ultra-high-performance liquid chromatography (LC)-quadrupole time-of-flight HRMS with an electrospray ion source or an ultra-high-performance LC-Orbitrap HRMS with the electrospray ion source.
