| Abstract | Dissolved and particulate metal concentrations assessed in the Scheldt estuary in the period 1978-1995, yield a clear indication that the levels of all metals decreased significantly. A comparison with other estuaries classifies the Scheldt as being moderately polluted for all metals in the dissolved phase, but as being fairly high polluted in the particulate phase, especially for Cd. However, even the dissolved metal concentration fractions in the Scheldt are still between 10 to 50 times enriched compared to total metal concentrations in unpolluted seas and oceans. |
