AbstractFreshwater musselsVelesunio angasi (Sowerby) from Magela Creek, Alligator Rivers Region, Northern Territory, Australia, experimentally exposed to mean elevated Ra-226 water concentrations ranging between 0.95 and 1.85 Bq 1−1 for 28 days, accumulated Ra-226 in their tissue to mean concentrations ranging from 2.8 to 4.8 Bq per gram of dry tissue. The Ra-226 (log10) was accumulated in a linear pattern over exposure periods of 28 and 56 days. Mussel size and sex had little or no effect on… 
An experimental study of 226Ra and 45Ca accumulation from the aquatic medium by freshwater turtles (fam. Chelidae) under varying Ca and Mg water concentrations

TLDR
The capacity of E. dentata to accumulate 226Ra from the aquatic medium is about two orders of magnitude less than that of the tissue of the freshwater mussel Velesunio angasi exposed under similar experimental conditions.
Radium‐226 accumulation in Florida freshwater mussels
TLDR
Mussels from augmented lakes displayed higher 226 Ra in both shells and tissues than did mussels from nonaugmented lakes, and large Elliptio mussels concentrated 226Ra in their soft tissues to levels about 1,000 to 25,000 times concentrations in lake water.
Water hardness determines 226Ra uptake in the tropical freshwater mussel.
Comparison between the mercury contamination in populations of Unio pictorum mancus (Mollusca, Bivalvia) from two lakes of different trophic state: the oligo-mesotrophic Lake Maggiore and the eutrophic Lake Candia
This research was designed to evaluate the influence of mussel (Unio pictorum mancus) size on mercury concentration in mussel soft tissues. It also evaluated the relationships between calcium,
Influence of body size and gender on valve movement responses of a freshwater bivalve to uranium

TLDR
The ability to demonstrate statistically significant (p ≤ 0.05) differences in valve movement responses between U exposure concentrations was enhanced, which may permit better estimates of the risk of the effects of U exposures to bivalve populations.

A field study of Ra accumulation in trout with assessment of radiation dose to man.
TLDR
Observed ratios were higher in all tissues of fish which had been in the ponds for a longer time, indicating that 226Ra concentrations in fish may increase with continued exposure to the nuclide, which would not likely preclude the establishment of a recreational lake at this site.
Accumulation of Iron, Manganese, Zinc and Cadmium by the Australian Freshwater Mussel Velesunio ambiguus (Phillipi) and Its Potential as a Biological Monitor
TLDR
The study suggests that V. ambiguus may not be a good short-term monitor of iron, but still may have potential as a long-term and site-comparison monitor of metals.
EXPERIMENTAL UPTAKE OF STRONTIUM-85 BY FRESH-WATER ORGANISMS.

TLDR
Factorial studies conducted to determine the effects of variable concentrations of calcium, magnesium, sodium and potassium on the uptake of dissolved strontium-85 by small bluegills, Lejomir macrochirus indicate that strontum-85 accumulation is related to age of the test organisms.
Australian Freshwater Mussel Velesunio ambiguus (Philippi) as a Biological Monitor for Zinc, Iron and Manganese
TLDR
Exposure of caged mussels in the zinc-contaminated Molonglo River, N.S.W., suggests that V. ambiguus is not a suitable species to monitor variations in zinc loads between sites, and does not accurately reflect environmental fluctuations of zinc, iron or manganese, although it may have potential for materials other than heavy metals.
THE RELATIONSHIP BETWEEN THE CONCENTRATIONS OF CALCIUM, STRONTIUM AND STRONTIUM-90 IN WILD BROWN TROUT, SALMO TRUTTA L. AND THE CONCENTRATIONS OF THE STABLE ELEMENTS IN SOME WATERS OF THE UNITED KINGDOM, AND THE IMPLICATIONS IN RADIOLOGICAL HEALTH STUDIES
The concentrations of Ca and Sr were measured in 20 surface fresh waters from the United Kingdom, and relations derived for the concentration of Sr and the ratio of atoms of Sr/1000 atoms of Ca, as a
Cationic responses of organs and haemolymph of Biomphalaria pfeifferi (Krauss), Biomphalaria glabrata (Say) and Helisoma trivolvis (Say) (Gastropoda: Planorbirdae) to cationic alterations of the medium
TLDR
Body organs exhibited cationic homeostasis, although attained with difficulty under very low Ca : Mg and Ca : Na ratios, and significant interspecific differences for haemolymph sodium were found.

Uptake of sodium and chloride by freshwater mussels

TLDR
The Sphaeriacea transport Na and Cl at significantly higher rates than Unionacea and the higher transport rates of the Sphaerium transversum Cl influx were similar to C. manilensis; however, Na influx was twice as high.
