Abstract
from the abstract, "Release of cadmium and manganese radionuclides from eelgrass leaves and root-rhizome s into seawater and seawater plus. . .(EDTA) was monitored over periods of six hours following incubations of 1 to 98 hours. Flux of both isotopes from tissues is initially rapid , and enhanced by the addition of EOTA . The initial release rate is in dependent of incubation time, indicating desorption of metals from exterior tissue surfaces. High initial release rates become rapidly attenuated . Fitting a power. . to the data proved valuable to inferring uptake capacity of tissues from observed metal release characteristics. In add i ti on to desorption , and diffusion from intercellular spaces and cells, and biologically controlled rel ease could be described with the aid of curve fits. Manganese apparently is released more slowly during latter phases of
release, pointing to greater biological accumulation potential. . ."
