The influence of particles on bioavailability and toxicity of pesticides in surface water

Environmental risk assessment is an essential part of the approval process for pesticides. Exposure concentrations are compared with ecotoxicological data obtained from standardized laboratory studies and, if available, from field studies to determine the ...

Bioaccumulation of antibiotics in wild freshwater invertebrates

Luiz Felippe De Alencastro, Marc Chevreuil

Occurrence and bioaccumulation of 20 antibiotics, including fluoroquinolones (FQs), sulfonamids (SAs), macrolids (MLs), tetracyclins (TCs),diaminopyrimidins (DPs) and nitro-imidazols (NIs) in an amphipod crustacean (Gammarus pulex) inhabiting in the small ...

Evaluation des flux de biphényles polychlorés (PCBs) dans les affluents du lac Léman à l’aide de capteurs passifs

The aim of this study is to investigate Lake Geneva’s tributaries using passive samplers in order to establish polychlorinated biphenyl (PCB) fluxes. Silicon rubber sheets are therefore deployed during six weeks at the mouth of eight tributaries and in fou ...

Validation of an integrative methodology to assess and monitor reductive dechlorination of chlorinated ethenes in contaminated aquifers

Christof Holliger, Pierre Rossi, Sonia Estelle Tarnawski

Bioremediation of tetra-and trichloroethene-contaminated aquifers is requently hampered due to incomplete dechlorination to the more toxic dichloroethene (DCE) and vinyl chloride (VC), indicating insufficient knowledge about the biological mechanisms relat ...

Potential exposure routes and accumulation kinetics for poly- and perfluorinated alkyl compounds for a freshwater amphipod: Gammarus spp. (Crustacea)

Gammarids were exposed to sediments from a deposition site located on the Rhone River (France) downstream of a fluoropolymer manufacturing plant. Gammarids accumulated to various extents four long-chain perfluoroalkyl carboxylic acids (PFCAs) from C-9 to C ...

Mapping environmental partitioning properties of nonpolar complex mixtures by use of GCxGC

Jeremy Samuel Arey, Jonas Gros, Petros Dimitriou Christidis, Deedar Nabi

Comprehensive two-dimensional gas chromatography (GC × GC) is effective for separating and quantifying nonpolar organic chemicals in complex mixtures. Here we present a model to estimate 11 environmental partitioning properties for nonpolar analytes based ...

Assessing metal bioaccumulation from estuarine sediments: comparative experimental results for the polychaete Arenicola marina

The purpose of this paper is to compare three approaches for providing information on the bioaccumulation potential of metals from contaminated sediments to the deposit-feeding polychaete Arenicola marina. We present metal (Ag, As, Cd, Cu, Pb and Zn) bioac ...

Sediment contamination assessment in urban areas based on total suspended solids

David Andrew Barry, Luca Rossi, Jonas Margot, Nathalie Chèvre Rossi, Romuald Curdy

Sediment represents an important compartment in surface waters. It constitutes a habitat or spawning site for many organisms and is an essential trophic resource for higher level organisms. It can be impacted by anthropogenic activities, particularly throu ...

Determination of trace metals accumulated and internalized by marine phytoplankton; interferences with colloidal organic matter

In the present work, we study the effects that aggregation of humic acids in seawater, and its adsorption to surfaces, can have on the determination of Cu and Pb accumulation by phytoplankton within the context of metal bioavailability studies, using the d ...

Cu and Pb accumulation by the marine diatom Thalassiosira weissflogii in the presence of humic acids

Metal complexation by dissolved organic matter, as humic acids, is considered to decrease metal bioavailability by lowering the free metal ion concentration. However, dissolved organic matter adsorption on cell surfaces can modify cell membrane properties, ...
