A simple extraction method for the determination of the endocrine disrupting nine phthalic esters, by gas chromatography/mass spectrometry (GC/MS) with electron ionization (EI) is described. These compounds were adsorbed on a disk-format solid phase from river water, rain water and atmosphere. A capital acetone and hexane were investigated as solvents for elution of the nine phthalic esters adsorbed on the solid phase. As a result, a capital acetone and hexane turned out to be very effective and a high recovery (about 100%) was obtained for nine phthalic esters in distilled water and reagent gas. This method was successfully applied to river water, rain water and atmosphere.
