N situ experiments, in which ionic copper was added to an enclosed area of the aquatic macrophyte Najas tenuifolia, showed that these plants can rapidly take up considerable amounts of the added copper in six hours. Epiphytes associated with these macrophytes took up the added copper even more rapidly, but also seemed to release the copper equally as fast. At the end of this three day experiment the added copper was distributed with 30–60% associated with the macrophytes and 15–20% in the water column. The remainder of the copper was associated with the epiphytes, sediments and perhaps also the walls of the plastic enclosure.
