Trace and Toxic Metal Uptake by Marsh Plants as Affected by Eh, pH, and Salinity.

摘要

A laboratory study was conducted to develop and refine methods for growing marsh plants under conditions of controlled pH, redox potential (oxidation-reduction conditions) and salinity as well as to determine the effects of these physicochemical conditions in the rooting medium on trace and toxic metal availability to plants. Reasonably successful methods were developed for growing marsh plants in the experimental systems. The successful methods as well as procedures which were not successful are discussed as are techniques for overcoming many of the experimental difficulties.
