These guidelines concentrate on the sampling and extraction of lipophilic persistent organic pollutants from seawater and also address special aspects of the sampling matrix. Those pollutants comprise the group of polycyclic aromatic hydrocarbons (PAHs) and chlorinated hydrocarbons (e.g., HCH, HCB, DDT group, chlorinated biphenyls (PCBs)). Usually, similar analytical methods are used for the determination of lipophilic pollutants in extracts from water samples and from sediments. Therefore, it is meaningful to harmonize analytical procedures and to refer to the respective references. (see 7. CHROMATOGRAPHIC DETERMINATION) However, it should be taken into consideration (e.g., for calibration) that the relative concentrations of the individual pollutants are different in water and sediment samples which is basically attributed to the compound’s polarity and, thus, their octanol/water partition coefficient (log Kow; Kow = Concentration in octanol phase / Concentration in aqueous phase)......
