Description
| - Nové přístupy v analýze obsahu steroidních estrogenů sedimentech; Farmaka, steroidní estrogeny, kontaminanty, sediment, GC/MS (cs)
- A wide range of estrogenic contaminants has been detected until now in the aquatic environment. Among them, natural and synthetic steroid estrogens, contained typically in municipal sewage treatment plant (STP) effluents, are in this respect the most potent chemicals. In our study, new GC/MS method has been developed for direct analysis of five major steroid estrogens (estrone, 17β-estradiol, 17α-ethinylestradiol, dienestrol and diethylstilbestrol) in river sediments. Four GC/MS systems employed for analysis of underivatized analytes in purified extracts were compared. Relatively low detection limits (1.5 - 5 ng/g dried sediment) and good repeatibility of GC splitless injections (RSD 1 - 2 %) were obtained in system employing low-pressure gas chromatography coupled to single quadrupole mass analyser (LP-GC/MS). The use of orthogonal gas chromatography (GCxGC) hyphenated with high-speed time-of-flight mass spectrometry (HSTOF-MS) enabled not only significantly better resolution of target anal
