Abstract

A method for the analysis of most common phthalate acid esters (9 secies) in biota samples by gas chromatography-mass spectrometry-selected ion monitoring mode is described. Phthalates in biota samples are extracted by organic solvent and purified by Florisil column. Phthalates are easily contaminated during extraction prodedure. Since the extraction and cleanup steps for biota samples generally are more complicate than those for water or sediment samples, we compared with contamination state of each sample work-up step. By applying this developed method, the overall recoveries ranged between 79 - 117% in biota sample which was spiked with standards. For phthalates used in this study, the quantitaive accuracy, elution pattern on Florisil column, and detection limits were also investigated.
