Boundary conditions for heavy metals at the air-sea interface
Provedor de dados: 27
Autores: Dehairs, F.A.; Dedeurwaerder, H.; Dejonghe, M.; Decadt, G.; Gillain, G.; Baeyens, W.F.J.; Elskens, I.
During 1980 and 1981 the aerosol burden as well as the wet and dry atmospheric fall-out of Cu, Cd, Pb, Zn, Fe and Mn to the sea have been studied in the Belgian coastal area. Atmospheric Cu, Zn and Cd are observed to be introduced into the sea mainly by wet fall-out, while Fe, Mn and also Pb have a dry and wet fall-out of similar magnitude. Of these elements, Cu, Zn and Cd have the highest washout factors. Furthermore, for all elements, excepted Mn, discrepancies exist between washout factors above land and sea, with values up to 5 times larger above the sea.On the scale of the North Sea, atmospheric fall-out of Cu, Zn, Pb and Cd exceeds by one order of magnitude the combined input of the rivers Scheldt, Rhine and Meuse, while fall-out of Fe and Mn is of...

Biogeochemical behaviour of Cd, Cu, Pb and Zn in the Scheldt estuary during the period 1981-1983
Provedor de dados: 27
Autores: Baeyens, W.F.J.; Elskens, M.; Gillain, G.; Goeyens, L.
Cu, Zn, Cd and Pb have been analysed in suspended matter and water samples from the Scheldt estuary, collected during five cruises between May 1982 and May 1983. In order to evaluate the overall metal behaviour in the estuary, continuous longitudinal profiles of the total, the particulate and the dissolved metal concentrations are discussed in relation to various specific physico-chemical parameters. By means of correlation and multi-regression techniques, several estuarine processes could be identified which dominate and/or control the behaviour of the individual trace metals in three distinct areas of the Scheldt estuary. The behaviour of the four selected metals was found to show some common features, but is besides this also characterised by many...

Trace metals in the eastern part of the North Sea: 1: Analyses and short-term distributions
Provedor de dados: 27
Autores: Baeyens, W.F.J.; Gillain, G.; Decadt, G.; Elskens, I.
Advanced analysis procedures for dissolved and particulate trace metals in sea water have been developed and tested in international intercalibration exercises. Since these tests gave evidence that reliable data could be produced with such methods, trace metal distributions in the coastal waters of the eastern North Sea were studied.The spatial distributions of most dissolved and particulate trace metals are, at least qualitatively, similar. Their concentrations decrease with distance from the coast and the mouth of the Scheldt estuary ( particulates much stronger than dissolved species). The salinity gradient is similar (but opposite) to the trace metals and turbidity gradients. The five trace metals studied can be subdivided into two groups on the basis...

Trace metals in the eastern part of the North Sea: 2. Flows of Cd, Cu, Hg, Pb and Zn through the coastal area
Provedor de dados: 27
Autores: Baeyens, W.F.J.; Gillain, G.; Ronday, F.; Dehairs, F.A.
The residual flow lines of the Belgian coast are more or less parallel to the coast except in the area where the northeasterly flowing watermass coming from the Channel encounters the southwesterly-oriented Scheldt outflow. The result is a residual hydrodynamical front with, at the northern side, a less saline estuarine watermass, and at the southern side a more saline marine watermass. From the steady-state salinity pattern, diffusion coefficients perpendicular to the residual flow were deduced; they ranged from 21 to 108 m².s&lt;sup&gt;-1&lt;/sup&gt;.The steady-state profiles of dissolved metals versus salinity indicate a dilution effect in the coastal-estuarine watermass and almost constant concentration in the marine watermass. Offshore fluxes of Cd,...

Concentration and microbiological utilization of small organic molecules in the Scheldt estuary, the Belgian coastal zone of the North Sea and the English Channel
Provedor de dados: 27
Autores: Billen, G.; Joiris, C.R.; Wijnant, J.; Gillain, G.
Concentrations and utilization rates of alanine, aspartate, lysine, glucose, glycollic, acetic and lactic acids have been determined on 6 occasions at least, during a full seasonal cycle in the water column of 3 stations (Scheldt estuary, coastal North Sea and English Channel) with greatly differing biological characteristics. No significant differences in substrate concentration could be detected between the 3 stations, although the rate of utilization of all substrates differed greatly, decreasing in the order estuarine &gt; coastal &gt; open sea environment. This apparent paradox is explained by aid of a simple model showing that the steady state concentration of a particular substrate is independent of its rate of production (and thus of consumption)...
