INDUSTRIAL SEWAGE IS THE WESER ESTUARY

Resumen

The in former years nearly exclusively agriculturally structured coastal areas of Lower Saxony recently undergo an increasing industrialisation. This process was introduced by the settlement of a Titandioxyd factory at the Weser estuary, which releases acid sewage. The problems, connected with the discharge of this sewage are discussed, as well as the tests performed in order to prevent a possible overstrain of the Weser water. The hitherto gained results are described and preliminarily interpreted. The recent, partly surprising biological development cannot be traced back to a measurable ecological change in the Weser estuary and therefore is inducement to think over critically the applied procedure.
