| In order to obtain representative dissolved and solid samples from the aquatic environment, a spectrum of sampling methods are available, each one with different advantages and drawbacks. This article evaluates the use of discrete sampling and time-integrated sampling in illustrating medium-term spatial and temporal variation. Discrete concentration index (CI) calculated as the ratio between dissolved and solid metal concentrations in grab samples are compared with time-integrated concentration index (CI) calculated from suspended particulate matter (SPM) collected in sediment traps and labile metals measured by the diffusive gel in thin films (DGT) method, collected once a month during one year at the Seine River, upstream and downstream of the Greater... |

| Many social-ecological system(SES)-based approaches have been proposed to address environmental problems. Most social-ecological frameworks developed to date, however, lack clear operational linkages between humans and nature to efficiently guide SESs toward resilience. A conceptual framework designed to be operational is therefore necessary, as well as a network of research platforms with which to apply it. We defined explicit coupling processes that can be used as leverages to pilot an SES toward sustainability. We proposed to formalize an SES as a dynamic entity composed of two coupling interfaces, i.e., adaptive management and ecosystem services, both set within a landscape context to provide an actionable framework. These interfaces describe the way... |

| Le PIREN-Seine s’intéresse à la présence dans le bassin versant de la Seine de contaminants d’origines agricole, industrielle et domestique depuis une vingtaine d’années. Ces polluants, qui se retrouvent parfois à des concentrations très faibles dans l’eau, peuvent avoir des impacts sur l’homme et l’environnement qui restent peu connus. La présence de ces substances toxiques suscite un intérêt majeur auprès des gestionnaires de la ressource comme des consommateurs. Les perturbations endocriniennes, les effets cancérigènes, la présence de résidus de médicaments sont autant de sujets d’inquiétude largement médiatisés et débattus. Pour garantir la protection de la santé humaine et du milieu aquatique, la réglementation a défini des normes de qualité... |
