Elodea canadensis

In another study with rooted macrophytes, Navicula sp. and Elodea canadensis rapidly accumulated lead from solutions containing 1.0 mg Pb+2/L, i.e., 70 mg Pb/kg dry weight per minute the process was overwhelmingly passive (Everard and Denny 1985). Depuration was rapid 90% of the lead sorbed during the first hour by shoots of Elodea was released within 14 days after transfer to clean water, though 10% seemed to be irreversibly bound (Everard and Denny 1985).

A recent literature review [13] listed 17 wetland plants capable of RDX removal from water, or removal accompanied by RDX incorporation into plant biomass. The emergent wetland plant Phalaris arundinacea (reed canary grass) and the submerged wetland plant Elodea canadensis were particularly suitable for RDX bioremediation using constructed wetlands in terms of RDX removal efficiency and relative persistence [39], Studies with the model aquatic plant M. aquaticum demonstrated that RDX removal from water was a first-order rate process, similar to TNT removal [14,43], However, the first-order rate constants for RDX removal were 3.0 x 10-5 L g 1 FW h 1 versus 2.2 x 10 3 L g 1 FW h 1 for TNT removal at the same conditions [14],... 

The masses of vegetation produced by weed species such as elodea (Elodea canadensis Michx.), coontail (Ceratophyllum demersum L.), and Eurasian watermilfoil Myriophyllum spicatum L.) remove herbicide residues from water (14). Najas sp. and Potamogeton sp. in plastic pools...

The natural occurrence of the 15-cw-isomer of violaxanthin [5,6,5, 6 -diepoxy-5,6,5, 6 -tetrahydro-/3,j8-carotene-3,3 -diol (13)] as a minor (0.6% of total carotenoid) constituent of Viola tricolor has been reported. Isomerization to fra 5-violaxanthin and c.d. correlation established the (35,5i ,6S,3 5,5 / ,6 S)-chirality. Reinvestigation of the carotenoids of Elodea canadensis failed to reveal any eloxanthin . It is proposed that the name be abandoned. A minor carotenoid from Valencia orange peel has been identified as jS-citraurin epoxide [3-hydroxy-5,6-epoxy-5,6-dihydro-8 -apo-j8-caroten-8 -al (14)]. 

It occurs by one of two methods. In Canadian pondweed (Elodea canadensis) the male flowers break off and float downstream until they contact the female flowers. In Zostera, a...
