Caractérisation de l’état de contamination de l’axe Seine

Fulvia Baratelli, Fabrice Alliot, Sophie Ayrault, Marc F. Benedetti et autres

This chapter presents a characterization of the state of contamination of the Seine River and its longitudinal variability from upstream to downstream, at the basin scale. Seven studies dealt with this topic during the 8th phase of the PIREN-Seine program by combining …

New insights into detecting alizarin from autofluorescence in marked glass eels

Mélanie Gaillard, E. Parlanti, Mahaut Sourzac, Franck Couillaud et autres

Alizarin detection in fish fins is extensively employed because it is easy to use. However, in eels, the eelGFP fluorescent protein may impede the detection of the fluorescent markers in the eel tissues. The study tests the effectiveness of three of the …

Chemical characterization of water extractable organic matter from plants: A better understanding of soil dissolved organic matter sources and path in permafrost thawing regions

Alienor Allain, Marie Alexis, Yannick Agnan, G. Humbert et autres

In present permafrost thawing context, dissolved organic matter (DOM) is a key component that controls organic and inorganic material transfer from soil to hydrographic systems. In terrestrial environments, vegetation is the main source of DOM, before degradation by microorganisms. DOM stoichiometry, aromaticity, …
