| Abstract: | The chemical composition of particulates and organic pollutants in TSP,precipatation matter of Jinan Area were studied with GC/MS.It's found there are more than 170 organic pollutants in the aerosol:hydrocarbons,acids,phthalates ,alchohols,aldehydes,ketones,phenol,amide,benzene,naphthalene and its derivative,nitro chemical compounds,biphenyl and its derivative,triphenyl,indene,pyrene,flaorene,anthracene,benzo and polycyclic aromatic hydrocarbon(PAH)compounds like pyrene.Free radical of various atmospheric aerosols was detected with Electron Spin Resonance(ESR).It's observed that humic acid free radical exists in TSP over the Refinery Plant,Power plant and Shandong University in Jinan,and that the free radical can exchange with water,dissolve partly in water and form a new free radical. |
