The Distribution of the Major and Some Minor Elements in Marine Animals Part II. Molluscs

Abstract

INTRODUCTIONIt has been known for a long time that the soft tissues of molluscs contain relatively high concentrations of certain trace elements—mainly transition metals (see, for example, Vinogradov, 1953; Bowen, 1966). However, with the exception of the work by Brooks & Rumsby (1965) on the occurrence of 12 elements in 3 New Zealand bivalves, most of the investigations have concerned the distribution of only one or two elements. This has prevented a study being made of possible interelement correlations. The present work was carried out in an endeavour to determine the usual levels of several minor elements in a variety of molluscs from the Irish Sea and to seek evidence for such correlations.

Cathodoluminescence of Recent biogenic carbonates: environmental and ontogenetic fingerprint

“…It is evident that the luminescence of bioeroded surfaces is due to external factors and was not produced by the mollusc biomineralization process. According to Segar, Collins & Riley (1971), analysis of P. maximus revealed a Mn content of 4.9 to 12 ppm (Milliman, 1974, reports values as high as 130 ppm for a Pecten sp.) for the shell, whereas the soft parts average 140 ppm and a value of 410 ppm was recorded for the gut and digestive gland (Segar, Collins & Riley, 1971).…”

Bryan (1973) found 15300 ppm Mn (90% of the total Mn of the animal) in the kidneys of P. maximus.…”

Metals in molluscs and associated bottom sediments of the southern baltic

“…The ability of marine mussels to biologically incorporat9 trace metals in their tissues has been well estabhshed; most of the studies have been carried out on the soft tissue (Amiard et al, 1986;Bloom & Ayling, 1977;Bryan, 1980Bryan, , 1983Coleman et al, 1986;Cossa et al, 1979;Davies & Pirie, 1980;Di Giulio & Scanlon, 1985;Farrington et al, 1983;Galloway et al, 1983;Gault et al, 1983;Goldberg, 1975;Goldberg et al, 1978Goldberg et al, , 1983Hung et al, 1981Hung et al, , 1983Johnson & D'Auria, 1980;Julshamn, 1981;Karbe et al, 1977;Langston, 1986;Martinci~ et al, 1984;M6ller et al, 1983;Phillips, 1976aPhillips, , 1976bPhillips, , 1977bPhillips, , I977c, 1978Popham & D'Auria, 1983a, 1983bRitz et al, 1982;Segar et al, 1971;Slabyj & Carpenter, 1977;Szefer, 1986;Szefer & Szefer, 1985;Szefer & Wenne, 1987). However, the number of articles on the concentration or distribution of metals in shell material, particularly relating the metal concentration in the soft tissue to that in the shell is scanty (A1- Dabbas et al, 1984;Bertine & Goldberg, 1972;Carriker et al, 1980bCarriker et al, , 1982Chow et al, 1976;Ferrell et al, 1973;<...>…”

Biochemical changes in selected body tissues of the scallop Patinopecten yessoensis under long-term exposure to low Cd concentrations

“…In contrast to other commercially important bivalves (oysters and mussels), the scallop Patinopecten yessoensis can accumulate in its digestive system considerable amounts of Cd, even in a contamination-free area (Lukyanova and Evtushenko, 1982;Khristoforova, 1983). Many authors (Mullin and Riley, 1956;Brooks and Rumsby, 1965;Segar et al, 1971;Bryan, 1973;Nielsen and Nathan, 1975;Vattuone et al, 1976) find this accumulation to be typical of all molluscs of the family Pectinidae.…”
