Alzieu, Claude - 1977The laboratory tests showed that the diflubenzuron does not present acute toxicity to shellfish and fish, but can affect the survival rate of Artemia salina and Palaemonetes varians, when its concentration rises to the level of its water solubility. The insecticide persistence in sea water had been...Contributeur (s):

Alzieu, Claude - 1976Les composés organohalogénés sont réputés pour leur stabilité qui a pour conséquence leur rétention dans les tissus des organismes vivants lorsque ceux-ci se retrouvent dans un milieu contenant de tels composés. C'est pourquoi l'éventualité d'une accumulation dans la faune marine...Contributeur (s):

Alzieu, Claude - 1972The necessity to combat oil slicks makes it necessary to assess the relative effectiveness and toxicity of dispersal agents used. This is usually done by using individual or groups of indicator organisms. The theory behind the various approaches is outlined, and some considerations are listed for...Contributeur (s):

Alzieu, Claude - 1979Les diphénylpolychlorés rassemblent un ensemble de substances et isomères qui possèdent un groupement diphényl sur lequel sont fixés de 1 à 10 atomes de chlore (chloro-homologues). Les formulations commerciales, caractérisées par leur teneur en chlore, sont des mélanges en proportion variable de...Contributeur (s):

Alzieu, Claude - 1989This report synthesizes the knowledge on the biogeochemical cycle, bioconcentration processes and ecotoxicity of tin and organotins in the marine environment. Concentrations levels, biomethylation mechanisms and exchanges between sediments and water are assessed. Emphasis is given on tributyltin...Contributeur (s):

Troadec, Jean-paul / Alzieu, Claude - 1986La conservation des environnements côtiers revêt une importance croissante compte tenu: - des niveaux généralement élevés atteints par la production biologique, - du rôle que jouent les milieux littoraux dans le cycle biologique de nombreux stocks halieutiques, - de la qualité des milieux que...Contributeur (s):

Alzieu, Claude / Duguy, Raymond / Babin, Philippe - 1982Contamination of Delphinidae's fetuses and newborn has been determined from the organochlorine levels found in the fetuses and pregnant female organs, and in the milk of lactating females, for 4 dolphins and 3 porpoises. High levels of these components show an important transference of mother...Contributeur (s):

Experiments in oyster-breeding areas where oyster Crassostrea gigas suffers from anomalies of calcification, show an obvious correlation between the importance of the malformation of shells and the vicinity of port areas where a great number of boats usually stay. Organotin compounds contained in...Contributeur (s):

Alzieu, Claude / Barbier, Georges / Sanjuan, Jane - 1987The ban of tributyltin compounds in antifouling paints induced a strong decrease in the level of tin in Arcachon bay. At the same time, copper inputs have increased tenfold since 1982 owing to the widespread use of paints containing cuprous oxide. In spite of this large input, the statistical...Contributeur (s):
