摘要

It has been known that inorganic phosphate inhibits the precipitation of calcium carbonate in artificial sea water. This work addresses the question of whether phosphate also affects the deposition of CaCO sub 3 in the exoskeletons of invertebrates. Tetrasodiumpyrophosphate and pentasodiumtripolyphosphate in concentrations of 15 ppM caused abnormality, mortality, and inhibition of shell deposition in trochophore larvae of the oyster Crassostrea. Inhibition of shell growth resulting from pollution at 15 ppM could be expected in Rangia with orthophosphate, tetrasodium pyrophosphate, and sodiumtripolyphosphate, in Helisoma with tetrasodium pyrophosphate, and pentasodium tripolyphosphate, and in larvae of Crassostea the relative inhibitory action of shell growth was tetrasodiumpyrophosphate > sodiumtripolyphosphate > sodium orthophosphate greater than or equal to sodium hexametaphosphate. 4 refs.
