Description	The effect of various operational parameters (i.e. temperature of extraction, number of static cycles and extraction solvent mixtures) on the PLE efficiency were investigated in this study. Results obtained by the optimized PLE procedure were compared with conventional Soxhlet extraction (the same extraction solvent mixtures hexane-dichloromethane (1:1 v/v) and hexane-acetone (4:1 v/v) were used). The recoveries obtained by PLE operated at 90- 120 ?C were either comparable to %22classic%22 Soxhlet extraction (for higher- chlorinated PCB congeners and DDT group) or even better (for lowe rchlorinated analytes).

Výsledky získané optimalizovaným PLE- procesem byly porovnány s konvenční extrakcí podle Soxhleta (stejná extrakční směs hexan-dichlormethan 1:1 v/v a hexan-aceton 4:1 v/v). Výtěžnosti zjištěné PLE při teplotě 90-120 °C byly srovnatelné s %22klasickou%22 Soxhletovou extrakcí (pro výšechlorované kongenery PCB a pro DDT) nebo dokonce vyšší (pro nížechlorované analyty).
