| Laboratory assays have been performed, using mussels contamined with Dinophysis, in order to assess potential depurations kinetics. Mussels samples from Seine bay, Douarnenez bay and Vilaine bay have been tested . From these assays, which are to be performed in 1989; two main results are stressed : 1) when the toxicity level is near 0,5 MU/g of hepatopancreas*, depuration is undedectable during twelve days, 2) when the toxicity level exceeds 1 MU/g,depuration is important during the first eight days. *(quarantine level used by Japanese authorities) . |

| In January 2010, the toxin-producing dinoflagellates Dinophysis acuminata and D. caudata (10³ cells·l-1) were detected in Mar Azul during routine plankton monitoring in Buenos Aires Province coastal waters, Argentina. Wild clams Mesodesma mactroides and Donax hanleyanus from Mar Azul intertidal beach, which are part of the diet for local inhabitants and tourists, tested positive with the offcial lipophilic mouse bioassay. This paper focuses on the detection of Diarrhetic Shellfsh Poison (DSP) toxins in these samples using a HPLC-FLD pre column derivatization procedure. The data showed that shellfish were contaminated with complex DSP toxin profiles composed of Okadaic Acid (OA), Dinophysistoxin-1 (DTX-1), Acyl-Dinophysistoxin-1 (Acyl-DTX-1) and... |

| This document presents the results obtained through the French Phytoplankton and Phycotoxins Monitoring Network (REPHY), concerning the presence of toxic and harmful phytoplankton species along the French coast, from 1984 to 1995. The network REPHY is briefly described. Then the different species, and their associated events, are reviewed : first, species toxic to shellfish consumers, e.g. Dinophysis spp. and Alexandrium minutum, which respectively produce diarrheic and paralytic toxins ; then, species which are toxic or harmful for marine fauna (fish, shellfish). The monitoring results are preceded by the main knowledge on taxonomy, distribution, biology, ecology and toxicity of the concerned species. A final synthesis illustrates the distribution of... |

| This document describes and harmonizes detection methods of diarrheic (DSP) and paralytic (PSP) phycotoxins, for the laboratories of the Direction of Coastal Environment of IFREMER, which work in the framework of the French Phytoplankton and Phycotoxins Monitoring Network. These toxins, produced by a few phytoplankton species which regularly occur in sea water, accumulate in shellfish, which become toxic. Analysis is performed on an extract of digestive gland (DSP), or of total flesh (PSP), of shellfish. The described methods are meuse-tests, which are, at the present time, the only methods available to be used in the framework of a monitoring network. The method for diarrheic toxins is not standardized, with a threshold adapted for monitoring purposes. At... |
