These headlines may suggest that pollution of the North Sea is a recent event. This is not the case. Although no data are available (methods simply did not exist), it is safe to assume that emission (both into air and water) of heavy metals already started to increase in the 19th cen- tury. The growth of cities and introduction of sewer sys- tems led to the discharge of raw sewage and sewage sludge. The introduction of man-made (xenobiotic) organ- ic chemicals and their subsequent emission into the North Sea commenced before the second world war. The shallower and coastal areas of the North Sea receive the highest concentrations of these pollutants. Not unexpectedly, these areas - some Norwegian fjords, the Dutch coast, the German Bight - show signs of ecosystem deterioration and eutrophication. A certain percentage of the pollutants does not remain in the North Sea but is "exported" to the Atlantic. The North Sea therefore con- tributes to the global input of pollutants to | | 出版日期 | Book 1988 | | 關(guān)鍵詞 | Coast; Eutrophication; biology; chemistry; contaminants; ecosystem; ecotoxicology; environment; estuaries; ma | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-642-73709-1 | | isbn_softcover | 978-3-642-73711-4 | | isbn_ebook | 978-3-642-73709-1 | | copyright | Springer-Verlag Berlin Heidelberg 1988 |
