    Acute and chronic toxicity of tributyltin (TBT) to pediveliger larvae of the bivalve Scrobicularia plana (1995)

    Notes: Abstract A static renewal test was run for 30 d to assess the effects of the antifoulant tributyltin (TBT, nominal concentrations of 50, 125, 250 and 500 ng Sn l-1) on the survival and growth of 240 μm-long pediveliger larvae of the bivalve Scrobicularia plana (da Costa) settling in fine sand. Exposure to nominal TBT levels of ≥125 ng Sn l-1 (actual range of 37 to 102 ng Sn l-1, as analysed) resulted in substantial mortalities and negligible shell growth of individuals. More importantly, larval shell growth at the lowest concentration tested (i.e. nominal 50 ng Sn l-1 or 14 to 32 ng Sn l-1, as analysed) was significantly reduced (by a factor of ∼4) and grossly abnormal. In contrast, some control postlarvae had begun developing siphons as they attained a length of 600 to 700 μm by the end of this test, thereby completing metamorphosis and becoming juveniles. The results are discussed in relation to the widespread disappearance of S. plana in North Atlantic European estuaries during the 1980s and the concurrent TBT pollution in their waters. It is inferred that TBT is likely to have contributed to the reported demise of clam populations by preventing the successful and timely progress of their pediveliger larvae.

    Notes: [Auszug] Alexandrowicz has noticed that some of the components of the dorsal musculature in crustaceans have a coarse and others a fine cross-striation2'3, and suggested that they may form two systems, one for slow and the other for fast contractions4. These muscles appeared, therefore, to possess the above ...

    Notes: [Auszug] Nephtyid polychaete worms are found worldwide and are one of the commonest carnivores inhabiting sediments from the intertidal zone to abyssal depths. The family Nephtyidae comprises about 100 species; these are grouped in four genera but most belong to the genera Nephtys and Aglaophamus4. To date, ...

    Recent trends in research on heavy-metal contamination in the sea (1980)
    Springer
    Helgoland marine research 33 (1980), S. 6-25

    Topics: Biology
    Notes: Abstract Recent trends in the study of metal contamination in the sea are reviewed. Aspects of contamination which are considered include the input of metals to the sea and their deposition in the sediments, the influence of environmental and biological factors on the accumulation of metals by the biota and the use of organisms as indicators of contamination. Laboratory studies on the biological effects of metals and the problem of monitoring effects in the field are discussed. The importance of the metabolism of metals by the biota is stressed since it is relevant to the adaptation of organisms to chronic contamination and to the attainment of very high levels in some commercial species. Finally, the abatement of contamination is discussed.
