duration of exposure in clean water

Fig. 12.5. Mass of phenanthrene extracted from ceramic dosimeters after purging in a flow-through system with clean water for up to 96 days [3]. Bars represent the average of three samplers with vertical lines representing the standard deviation.

Fig. 12.6. Comparison of ceramic dosimeter derived and time-averaged snapshot sample determined aqueous PAH concentrations for six sampling times over the course of 1 year in one groundwater borehole. For absolute agreement between the two sampling methods, symbols should lie on the diagonal line. Reprinted from Bopp et al. [2] with permission from Elsevier.
