| Phosphogysum (PG) or agricultural gypsum, a solid waste from the phosphate fertilizer industry, is used as soil amendment, especially on soils in the Cerrado region, in Brazil. This material may however contain natural radionuclides and metals which can be transferred to soils, plants and water sources. This paper presents and discusses the results of physical and chemical analyses that characterized samples of PG and compares them to the results found in two typical soils of the Cerrado, a clayey and sandy one. These analyses included: solid waste classification, evaluation of organic matter content and of P, K, Ca, Mg, and Al concentrations and of the mineralogical composition. Natural radionuclides and metal concentrations in PG and soil samples were... |

| The degradation in the quality of silver eel and their health could have been a major factor in the collapse of the European eel (Anguilla anguilla) population. However, the health status of the spawners has been poorly studied until now. This study evaluated the quality of migrant male silver eels from four Mediterranean habitats in France presenting different degrees of contamination: Canet-Saint-Nazaire, Salses-Leucate and Bages-Sigean lagoons and La Berre River. We considered pathogens including Anguillicoloides crassus and EVEX virus and the concentration of chemical contaminants including PCBs, OCs and heavy metals. Our study results revealed different patterns of pollution and infection in the four habitats, with high individual variability. No... |

| Over the past two decades, soil ecotoxicologists have made strides in utilizing the basic concepts and advancements in soil zoology and ecology. They have applied the existing tools, and developed new ones to investigate how chemical contamination can affect soil ecosystems, including the degradation or destruction of soil quality and habitats or the diminishment of belowground biodiversity. Soil ecotoxicologists are applying a suite of standard protocols, originally developed as laboratory tests with single chemicals (e.g., pesticides), and further enhancing both the approaches and protocols for the assessment of contaminated lands. However, ecological relevance of some approaches remains unresolved. The authors discuss the main challenges for a coherent... |

| Les journées de microbiologie sanitaire sont organisées chaque année par le Laboratoire Santé, Environnement et Microbiologie (LSEM). Ces journées permettent de réaliser un bilan des activités liées aux missions de Laboratoire National de Référence Microbiologie des coquillages ainsi que de la surveillance (REMI). Les derniers résultats de la recherche menée au LSEM ou dans les Laboratoires Environnement Ressource (LER) sont également présentés. En 2013, 102 personnes ont participé à ces journées. Y participaient, des représentants de l’administration centrale (DGAL et INVS), de l’administration locale (ARS, DDTM, DDPP, CIRE), des agences de l’eau, des professionnels (CRC) et des laboratoires agréés. |

| This paper provides an overview of the cleanup and redevelopment of contaminated properties known as "brownfields." It has three principal parts. First, we introduce the brownfields phenomenon and its drivers, drawing on the body of available empirical evidence to discuss characteristics of individual brownfield redevelopment projects. Second, we present findings from a recent study we have conducted that examines the relative attractiveness to private developers of public interventions to promote brownfields redevelopment. Third, we briefly summarize some of the problems with brownfields development and policy and propose an approach to promote wider societal benefits of brownfields development. We conclude with several broad questions about brownfields... |

| Concentrations of 6 trace metals (Ag, Cd, Cu, Ni, Pb, Zn) in the muscle of 2 sharks (Galeus melastomus and Scyliorhinus canicula), 4 teleosts (Helicolenus dactylopterus, Lepidorhombus boscii, Micromesistius poutassou and Phycis blennoides) and 1 crustacean (Nephrops norvegicus) were compared between the Bay of Biscay (Atlantic Ocean) and the Gulf of Lions (Mediterranean Sea). Although average concentrations and the trace element pollution index were generally higher in the Gulf of Lions, significant differences between the two ecosystems were only found for Zn for Helicolenus dactylopterus, and for Ag and Cu for the crustacean N. norvegicus. Moreover, some relationships between trophic level or size and metal concentrations were found for these two... |

| Dans le cadre du programme national "REJETS URBAINS EN MER", développé par l'IFREMER, en collaboration avec l'Agence de Bassin Rhône Méditerranée Corse, des études sur le comportement d'un effluent émis par un émissaire en profondeur ont été réalisées. Complétant des mesures courantométriques et hydrologiques de longue durée, en un point à la sortie de l'émissaire de TOULON EST, deux modèles mathématiques ont été appliqués pour reproduire et étudier le rejet pendant les deux étapes de dilution. · Le modèle JET, développé par la SOGREAH, a été testé et comparé avec des mesures in situ. Les variations des résultats en fonction des conditions du milieu rencontrées pendant un cycle annuel ont été étudiées. Un modèle de transport et mélange multicouches a été... |
