PAH metabolites in fish bile: From the Seine estuary to Iceland.

Polycyclic aromatic hydrocarbons (PAH) are environmental contaminants that pose significant risk to health of fish. The International Workshop on Integrated Assessment of Contaminant Impacts on the North Sea (ICON) provided the framework to investigate biomarker responses as well as contaminant concentrations side by side in marine ecosystems. Concentrations of the main PAH metabolites 1-hydrox...

Interactions between Volatile Reduced Sulfur Compounds and Metals in the Seine Estuary (France)

Concentrations of volatile hydrogen sulfide (H2S), carbonyl sulfide (OCS), methane thiol (MeSH), dimethyl sulfide (DMS), and dimethyl disulfide (DMDS) in the Seine estuary (France) were investigated in spring 2005 using samples collected from the first meter beneath the surface. Levels of dissolved metals (Ag, Cd, Cu, Zn, Ni, Co, Pb), suspended particulate matter, and particular organic carbon ...

Distribution of Nitrifying Activity in the Seine River (France) from Paris to the Estuary

T he distribution o f nitrification has been m easured with the 111 '( ( ) ; incorporation m ethod in the Seine River and its estuary during sum m er conditions. T he Seine River below Paris receives large am ounts o f am m onium through w astewater discharge. In the river itself, this am m onium is only slowly nitrified, while in the estuary nitrification is rap id and com plete. We show that ...
