Environmental effects of dredging. Environmental effects of dredging technical notes. Plant bioassay of dredged material. Technical notes
Recently, a solid-phase plant bioassay was developed to test sediment for contaminants that are potentially phytotoxic and may be bioaccumulated by plants (Folsom and Lee 1981a; Folsom, Lee, and Bates 1981). The solid-phase plant bioassay was shown to be an excellent tool for predicting whether or not contaminants (e.g., zinc and cadmium) were potentially bioaccumulated by the saltwater plant S. alterniflora. Folsom and Lee (1981a) pointed out, however, that the DTPA extraction data indicated that plant uptake from air-dried oxidized saltwater sediment would be substantially greater than from the same saltwater sediment under flooded reduced conditions. In addition, they suspected greater plant uptake once the excess salts were leached out and the sediments were dried. This technical note reports results of modifications to the original solid-phase plant bioassay to pursue this assumption.
