Le plomb en milieu marin. Biogeochimie et ecotoxicologie 5
Cossa, Daniel; Elbaz-poulichet, Françoise; Gnassia-barelli, Mauricette; Romeo, Michèle.
This report synthesises the knowledge on the biogeochemical cycle, bioconcentration processes and ecotoxicity of lead in the marine environment. Man induced changes on the lead cycle, especially along the French coasts are reviewed. Concentration levels, mechanisms and fluxes between geochemical reservoirs are assessed. Emphasis is given on sublethal effects and toxicity mechanisms. Quality standards used in European Community countries are listed. Conclusions and recommendations for environmental management and research are given.

Modélisation des contaminants chimiques dans une colonne d'eau. Modèle MOMO (MORGAN+MOCO). 5
Thouvenin, Benedicte; Gonzalez, Jean-louis.
Within the framework of the "Contaminants cycle and modeling" project of the BE department ("Biogeochemistry and Ecotoxicology") in Ifremer, two chemical contaminant modeling software were developed between 1998 and 2011 (Gonzalez JL, 2017): the MORGAN model (Model behavior of ORGANic contaminants in an aquatic environment) and the MOCO model (Surface Complexation MOdel for metallic COntaminants). These two models had been brought together in a single "zero-dimensional" software (known as MOMO), which made it possible to simulate the various processes affecting the behavior of chemical contaminants in a homogeneous mass of water (biodegradation, adsorption/desorption, photolysis, hydrolysis, volatilization, surface complexation, cation exchange,...
