| Description
| - Three alternative procedures were employed for isolation of polycyclic aromatic hydrocarbons (PAHs), their methyl-derivatives and sulphur analogues from fish tissue: (i) Soxhlet extraction, (ii) batch extraction enhanced by sonication and (iii) saponification of sample followed by reextraction of analytes into hexane. Soxhlet extraction using hexane-acetone (1:1, v/v) was found as the most efficient extraction technique, with analyte recoveries in the range 70-108 %. Within optimisation of clean-up step, several types of gel permeation chromatography (GPC) systems were tested: two types of polystyrene divinylbenzene copolymer gels (PSDVB), both %22soft%22 gel type (Bio-Beads S-X3) and %22rigid%22 gels type (PL gel and Envirogel) in combination with various mobile phases were compared. Bio-Beads S-X3 and mobile phase chloroform were found as the most appropriate for purifying of crude extracts prior to the final determinative step. High performance liquid chromatography with fluorimetric de

- Byly testovány 3 metody pro extrakci PAU z rybí tkáně (saponifikace, extrakce dle Soxhleta a sonikace). Pro přečištění extraktu byly porovnány eluční profily PAU a předpokládaných koextraktů na různých typech gelů. Pro optimalizovanou metody byly odhanuty nejistoty měření dvěma různými způsoby %22top-down%22 a %22bottom-up%22. (cs)
