- Title
Phytotoxicity of Chlorinated Benzenes to Typha angustifolia and Phragmites communis.

- Abstract
This article discusses research that investigated the phytotoxicity of hexachlorobenzene (HCB) and its two metabolites in terms of impairing the healthy growth of the common wetland plants Typha angustifolia and Phragmites communis. The retardation of growth was examined, as this criteria is a prerequisite for successful application of phytoremediation technologies. In their respective applications, Typha demonstrated a higher tolerance than Phragmites. Negative effects of sediments polluted with chlorinated benzenes increasingly impacted Typha as the number of chlorine atoms decreased. The varied toxicity of HCB's metabolites are attributed to levels of bioavailability and the ease with which it is taken up by plants.
