We investigated the bioaccumulation of hexachlorobenzene (HCB, LogK(OW)5.5) in a benthic charophycean macro_alga: Chara rudis. Chara species are a group of common freshwater algae with a complex body structure encompassing a protective layer of cortex cells surrounding large internode cells. The charophyte cell wall has many features in common with that of higher plants; therefore, they are useful models to investigate bioaccumulation mechanisms in general. We found that HCB diffused through the cortex and reached the cytoplam of internode cells. More than 90% of the HCB mass found in the organism was in the cortex and 10% in the internode cell cytoplasm. The cortex reached a pseudoequilibrium partitioning with water, and the bioconcentration factor was in the same range aquatic organisms such as phytoplankton. Charophytes are therefore very efficient accumulators of hydrophobic compounds. Based on the structural and ecological features of charophytes, we speculated on their possible use as biomonitors and bioremediation tools.
