## 5 Conclusions  
Determinations of PCB and PAH contents requires tedious analytical procedures. To facilitate the analyses of both groups of compounds, procedures for simultaneously preparing samples and their subsequent separation into fractions containing PCBs and PAHs are being developed. This study compared the effectiveness of sample cleanup methods proposed by [PERSON] and [PERSON] [32] and [PERSON] et al. [33] by comparing the recoveries of the com \begin{table}
