A Chain

The Wadden Sea and Zuider Sea used to form an internal sea which was separated from the North Sea by a chain of islands. In 1932 the Zuider Sea was enclosed by a dam 32 km in length. Owing to this, the Wadden Sea experienced changes in the normal tidal movement, the storm-surge levels and the configuration of the bed. This article discusses the movement of water and sand the Wadden Sea and its natural development since the enclosure of the Zuider.

From literature data it is calculated that on an annual basis, 11 to 17 tonnes of PCBs enter the North Sea. Largest sources are the Atlantic Ocean and the atmosphere: together they account for 60-79% of the total input. Sources with greatest impact are the rivers, sewers and sludge. Highest concentrations are found close to the Dutch shore and in the German Bight. The PCB levels result in adverse effects on the seal population in the Wadden Sea. Of the total world PCB production, at least 57% is still in use and their future dispersal into the oceans cannot easily be controlled. If the increase in ocean PCB concentration continues, it may ultimately result in the extinction of fish-eating marine mammals.
