| Pesticides used in viticulture create a potential risk for the aquatic environment due to drift during application, runoff and soil leaching. The toxicity of sixteen pesticides and one metabolite were evaluated on the growth of two marine microalgae, Tisochrysis lutea and Skeletonema marinoi, in 96-h exposure assays conducted in microplates. For each substance, concentrations of stock solutions were analytically measured and abiotic assays were performed to evaluate the chemical stability of pesticides in microplates. For two chemicals, microalgae exposures were run simultaneously in microplates and culture flasks to compare EC50 calculated from the two exposure systems. Results from chemical analyses demonstrated the low stability of hydrophobic... |

| The organochlorine pollution by chlordecone, an insecticide spread in the past in banana plantations, is now recognized as a major ecological, economic, and social crisis in Guadeloupe and Martinique Islands. Due to its physical and chemical properties, this molecule is particularly persistent in the natural environment. Volcanic soil of Guadeloupe and Martinique contain allophanes (amorphous clays), which favor chlordecone trapping due to their structure and physical properties. Thus, with this trapping ability, allophanes serve as a vector allowing chlordecone to contaminate runoff waters and, finally, the sea. In the present publication, several studies recently conducted in the Lesser Antilles have been compiled in order to evaluate the desorption of... |

| Evaluating the ecological impact of an oil spill is a complex issue requiring coherently articulated examination of the sequence of interactions that link the cell, where contaminants exert their effects, to the ecosystem, where interactions with human activities arise. This sequence of interactions traverses the frontiers between scientific disciplines (chemistry, toxicology, physiology, and fisheries ecology). Using the common sole (Solea solea L.) as a model species for the coastal habitats polluted by the "Erika" oil spill, our research project attempted to define indices of functional integrity that characterised the consequences of fuel exposure at the different biological levels. The coupling of field observations with experimental laboratory work... |

| Ce travail a permis de construire et de valider un indicateur d'évaluation du risque lié à la présence de pesticides dans les lagunes méditerranéennes françaises. Cet indicateur, le Quotient de Risque (QR) s'appuie sur une stratégie de suivi globale, adaptée au contexte des lagunes, de leurs fortes dilutions et de leur dynamique complexe, tout en prenant en compte l'effet des mélanges de pesticides dans les eaux. Pour cela, la liste des pesticides à rechercher en priorité pour les lagunes, ainsi que le mode, les sites et les fréquences d'échantillonnage ont été définis et discutés au regard des résultats du suivi annuel des étangs de Thau et de l'Or, réalisé en 2015-16 par échantillonneurs intégratifs POCIS. 90 pesticides prioritaires pour les lagunes ont... |

| L’impact du changement climatique sur la qualité et la pollution des milieux est souvent négligé par rapport à d’autres impacts plus médiatisés (e.g. événements climatiques et hydrologiques extrêmes, santé, trait de côtes, disponibilité des ressources en eau…). Les eaux et l’air de Nouvelle-Aquitaine, et à moindre mesure les sols, déjà significativement pollués, subiront pourtant plusieurs détériorations significatives, qui sont présentées et discutées dans ce chapitre. Certains de ces effets sont déjà visibles et vont s’aggraver dans le contexte climatique prévu. Il s’agit principalement, pour l’eau douce superficielle, de l’augmentation de la température, de la diminution des débits des cours d’eau, de l’évolution des espèces aquatiques et du... |

| This study screened binary mixtures of pesticides for potential synergistic interaction effects on growth of the marine microalgae Tisochrysis lutea and Skeletonema marinoi. It also examined the single and combined effects of three of the most toxic substances on microalgal physiology. Single substances were first tested on each microalgal species to determine their respective EC50 and concentration-response relationships. The toxicity of six and seven binary mixtures was then evaluated in microplate experiments on the growth of T. lutea and S. marinoi, respectively, using two mixture modelling approaches: isobolograms and the MIXTOX tool, based on Concentration Addition (CA) or Independent Action (IA) models. Significant cases of antagonism (for both... |
