| divalent metal accumulation in freshwater bivalves: an inverse relationship with metal phosphate solubility. | whole soft tissue concentrations of mn, co, ni, cu, zn, pb, cd and u were measured in two species of freshwater (unionid) bivalves (hyridella depressa and velesunio ambiguus) from a minimally polluted site in the hawkesbury-nepean river, south-eastern australia. although the mean concentrations of metals in the tissue were similar for each bivalve species, their patterns of accumulation were dissimilar. for each metal, positive linear relationships between tissue concentration and shell length ( ... | 2001 | 11482401 |
