| Measurements of dissolved and particulate Cd, Co, Cu, Fe, Mn, Ni, Pb and Zn have been made on a regular basis over a fifteen month period at stations across the Strait of Dover, as a part of the Fluxmanche programme. These measurements have been integrated with data on fluxes of water and suspended particulate matter also obtained within the Fluxmanche programme to provide estimates of fluxes of these elements into the southern North Sea. For Fe, Mn, and Pb, particulate fluxes are greater than dissolved fluxes, whilst the reverse is true for Cd, Cu and Ni. Significant daily changes in magnitude of the modelled fluxes of water through the Strait when combined with averaged metal concentrations over longer timescales, result in large changes of fluxes of... |

| Manganese, copper, zinc, cadmium and lead concentrations were determined in particulate and dissolved phases in the Seine river and its estuary. This site is characterized by macrotidal system, large-scale chemical industrial activities causing contamination of the river system, and by a turbidity maximum in the estuary. Statistical treatment involving principal component analysis of data has shown a marked difference in the behaviour of each metal in solution and suspended material. This phenomenon is related to variations in granulometric profiles, salinity, concentration of different ligands, and amounts of suspended material.... In solution, the behaviour of cadmium and lead is partly related to the gradient of salinity, while that of copper strongly... |
