Despite a growing scientific attention on ecological impact of emerging pollutants (EPs) such as pharmaceuticals, personal care products, and pesticides, knowledge gaps remain regarding mixture toxicity and effects on aquatic organisms. Several EPs were screened in seawater (Normandy, France), and the ecotoxicity of five compounds, chosen on their occurrence in ecosystems and use worldwide, was assessed and were the biocides methylparaben (MP) and triclosan (TCS), a pesticide degradation product (AMPA), and the pharmaceuticals venlafaxine (VEN) and carbamazepine (CBZ). The acute or sub-chronic toxicity, alone or in binary/ternary mixtures of three of them (CBZ, AMPA, and MP), was assessed on one marine and two freshwater organisms: Crassostrea gigas,... |

Le bulletin régional annuel contient une synthèse et une analyse des données collectées par l’ensemble des réseaux pour les différentes régions côtières. Des représentations graphiques homogènes pour tout le littoral français, assorties de commentaires, donnent des indications sur les niveaux et les tendances des paramètres mesurés. |

Antidepressants are among the most prescribed pharmaceuticals throughout the world. Their presence has already been detected in several aquatic ecosystems worldwide and their effects on non-target organisms justify the growing concern of both the public and regulatory authorities. These emerging pollutants do not occur as isolated compounds but rather as multi-component mixtures, which may lead to increased adverse effects compared to individual compounds. Freshwater and marine algae seem particularly sensitive to pharmaceuticals, including antidepressants. Studies assessing the toxicity of antidepressant mixture to algae focused mainly on binary mixtures of selective serotonin reuptake inhibitors. In the present experiment, the freshwater algae... |

European stakeholders engaged in combatting the eutrophication of the North Sea welcomed three Water Framework Directive innovations: a more holistic approach to quality, the binding nature of WFD objectives, and greater public participation. Twenty years later, however, there has been a disappointing amount of progress in the reduction of diffuse pollution. In the Seine River Basin, the amount of livestock rearing is low; yet the basin is subject to significant diffuse pollution due to agriculture. This paper reports our study of this case; we examine the literature on WFD implementation policy in order to identify the physical and social causes of this failure to reduce diffuse pollution. We show that the nitrates, phosphorus, and pesticides that affect... |

L’étude ECUME était une opération destinée à tester localement dans les eaux côtières du littoral normand, des outils développés nationalement lors de nombreux travaux, et pressentis pour être utilisés lors des prochaines campagnes d’évaluation de la qualité chimique des masses d’eau littorales pour la DCE. Ceci afin de déterminer la méthode la plus adaptée et opérationnelle de les déployer, et comparer leurs résultats entre eux et par rapport aux connaissances actuelles des niveaux de contamination. Trois sites ont été choisis : Chausey, baie des Veys et estuaire de Seine. Les résultats des analyses chimiques dans l’eau de mer grâce aux DGT, POCIS, SBSE, et dans les moules ont permis de confirmer le contraste du niveau de contamination en éléments traces... |
