Abstract: The organic pollutants in the Jialing River around Chongqing were studied by liquid-liquid extraction coupled with GC/MS.Through comparison of the obtained mass spectra of the detected peaks with those of the standard database,twenty organic pollutants were identified,which were straight-chain alkanes and their derivatives,aromatic compounds with one benzene ring,polycyclic aromatic hydrocarbons,phthalate acid esters and other organic compounds. -
