Effect of organic complexation on the behaviour of dissolved Cd, Cu and Zn in the Scheldt estuary
Provedor de dados: 27
Autores: Baeyens, W.F.J.; Goeyens, L.; Monteny, F.; Elskens, I.
Samples from the Scheldt estuary have been assayed for dissolved Cd, Cu and Zn using differential pulse anodic stripping voltammetry, either as total (after UV irradiation) or labile concentrations. Under these experimental conditions, labile concentrations ranged between 51-65% of total Cu, 16-66% of total Zn and 53-91 % of total Cd. The metal-organic interactions were assessed by evaluating (a) the distribution coefficient K&lt;sub&gt;d&lt;/sub&gt; for the distribution of the metals between the liquid phase (complexation) and their binding to particulate matter, and (b) the competitive effect exerted by inorganic complexing ligands using a multi-element interaction model. The proportion of organically bound metals (strong and labile) was estimated, in...

A box-model of metal flows through the Scheldt estuary (1981-1983 and 1992-1995)
Provedor de dados: 27
Autores: Baeyens, W.F.J.; Monteny, F.; Van Ryssen, R.; Leermakers, M.
The behaviour of Cu, Zn, Cd, and Pb in the Scheldt estuary was investigated in the periods 1981 to 1993 and 1995. The Hg behaviour was studied between 1992 and 1994. A box model was used to establish the relationship between the trace metal inputs and the fate of these pollutants in the Scheldt estuary. Annual budgets were calculated for particulate and dissolved trace metals. For Hg, seasonal budgets of the various species (inorganic Hg, methylmercury, Hg°) could also be calculated. These budgets allow an evaluation of the consistency of each individual flux or process, such as the inputs of the various metals into the North Sea, the sedimentation flux of particulate metals in the area of high turbidity, the evasional fluxes and the formation rates of...
