“…In a follow up study, 199 Hg-NMR was used to look at HgCl 2 binding to MLVs of PE, PS and egg PC (Delnomdedieu et al, 1992). Although not truly representative of the biological membrane, the single-lipid model systems used confirmed previous results that the amine group is a common binding site in PE and PS lipids (Delnomdedieu et al, 1992). xxx…”

“…This interaction was observed to be independent of acyl chain composition and more importantly, the Hg (II) affinity for PC is much less than for PE and PS. Delnomdedieu et al were unable to detect any interactions between Hg (II) and the PC lipid headgroup using 199 Hg-NMR because of the higher concentrations of Hg (II) needed which may have masked the decrease in PC signal (Delnomdedieu et al, 1992;Girault et al, 1996). In addition, natural membranes have also been used to produce micelle systems.…”

This review of aquatic ecotoxicology is presented in three parts. First, we discuss the fundamental concepts and stress the importance of its ecological basis and the complexity and diversity of the field of investigation, which result from actions and interactions between the physicochemical characteristics of the biotopes, the structural and functional properties of the living organisms, and the contamination modalities. Ecotoxicological mechanisms, regardless of the level of biological complexity, primarily depend on the bioavailability of the toxic products. Numerous processes control the chemical fate of contaminants in the water column and/or sediment compartments; accessibility to the biological barriers that separate the organisms from their surrounding medium depends directly on bioavailability. Second, we review the principal methodologies of the field, from in situ studies at the ecosystem/ecocomplex level to bioassays or single-species tests. Third, we focus on mercury, selected as a reference contaminant, in order to illustrate the main ecotoxicological concepts, the complementarity between field and laboratory studies, and the indispensable multidisciplinarity of the approaches.

AbstractThe system trihexyl(tetradecyl)phosphonium ([P 66614 ]Cl)/mercury chloride (HgCl 2 ) has been investigated by varying the stoichiometric ratios from 4:1 to 1:2 (25,50,75, 100, 150, and 200 mol % HgCl 2 ). All investigated compositions turn out to give rise to ionic liquids (ILs) at room temperature.

The system trihexyl(tetradecyl)phosphonium ([P 66614 ]Cl)/mercury chloride (HgCl 2 ) has been investigated by varying the stoichiometric ratios from 4:1 to 1:2 (25,50,75, 100, 150, and 200 mol % HgCl 2 ). All investigated compositions turn out to give rise to ionic liquids (ILs) at room temperature. The prepared ionic liquids offer the possibility to study the structurally and compositionally versatile chloromercurates in a liquid state at low temperatures in the absence of solvents. [P 66614 199 Hg NMR, Raman-and UV−vis spectroscopy, and cyclic voltammetry, among other techniques, and their densities and viscosities were determined. The [P 66614 ]Cl/HgCl 2 system shows similarities to the well-known chloroaluminate ILs (e.g., decrease in viscosity with increasing metal content after addition of more than 0.5 mol of HgCl 2 /mol [P 66614 ]Cl, increasing density with increasing metal content, and the likely formation of polynuclear/polymeric/ polyanionic species) but offer the advantage that they are air and water stable.
