Modeling of depuration of paralytic shellfish toxins in Chlamys nobilis and Perna viridis.

Uptake and depuration of paralytic shellfish toxins in the green-lipped mussel, Perna viridis: a dynamic model.

Uptake and depuration of paralytic shellfish toxins in the green-lipped mussel, Perna viridis, were investigated by exposing the mussels to dinoflagellates (Alexandrium tamarense, ACTI01) under laboratory conditions for 8 d, then depurating them in clean seawater for 14 d. First-order linear differential equations were set up for five tissue compartments: Viscera, gill, hepatopancreas, adductor...

The uptake, distribution and elimination of paralytic shellfish toxins in mussels and fish exposed to toxic dinoflagellates.

We exposed green-lipped mussels Perna viridis and black sea breams Acanthopagrus schlegeli to toxic dinoflagellates Alexandrium fundyense to evaluate the accumulation, distribution, transformation, and elimination of paralytic shellfish toxins (PSTs) in a controlled environmental condition. The mussels were fed A. fundyense for 7 days followed by 3 weeks of depuration, and the fish were fed tox...

Biokinetics of paralytic shellfish toxins in the green-lipped mussel, Perna viridis.

Accumulation and depuration of paralytic shellfish poisoning toxins by laboratory cultured purple clam Hiatula diphos Linnaeus.

Purple clams (Hiatula diphos Linnaeus) accumulate paralytic shellfish poisoning (PSP) toxins produced by a toxic strain of the dinoflagellate Alexandrium minutum Halim in a laboratory study. The maximal toxicity of PSP toxins attained 31.3m MU/g after 20 days exposure. The toxin profile of H. diphos was similar to that reported for A. minutum at the end of the exposure period; and GTX1 was domi...

Trophic transfer of paralytic shellfish toxins from clams (Ruditapes philippinarum) to gastropods (Nassarius festivus).

A local strain of the dinoflagellate Alexandrium tamarense (ATCI01), which predominantly produces C2 toxin, was fed to the clams (Ruditapes philippinarum) under laboratory conditions. Concentrations of paralytic shellfish toxins (PSTs) in the dosed clams were determined by High Performance Liquid Chromatographic (HPLC) analyses, and the clams were homogenized and then fed to the gastropods (Nas...
