Phosphorus, nitrogen and another pollutants in the Czech Elbe

Popis výsledku v původním jazyce

Water quality and downstream transport of classical pollutants show dramatic changes leading to a stable present situation. Now we can review the 50 years course and compare it with data from beginning of the industrial/pollution period. Basic data were published by F. Ullik for profile Decin (Tetchen) just upstream the standard profile Hrensko/ Schmilka in 1877 [1] and by F, Schulz for Vltava up- and downstream Prague in 1913 [2]. Their methodology is comparable to present one and their original data were only recalculated to a standard format. Standard monitoring of Czech rivers quality started &quot;step by step&quot; after year 1960 and up to the year 2009 data were open to public. Since 2009, data were obtained on request from river basin administrators (Povodí Vltavy and Povodí Labe). In addition, MKOL/IKSE Tables of water quality ended to the year 2010, too. For transport values, concentrations were multiplied by mean daily flows for individual sampling days and the year sum was then calculated based on 12 representing situations in equal intervals. Data are presented as means of ten-year periods to show changes in a most simple way. In the period 1981-90, the pollution reached a maximum and started to decrease. End of at the iron curtain brought a significant improvement: Many inefficient and water polluting companies disappeared and new wastewater treatment plants were constructed or upgraded. After a significant improvement, the situation re-mains stable. But &quot;new pollutants&quot; appear, especially pharmaceuticals, and eutrophication resist, leading to growing importance of organic carbon produced instream by phytoplankton beside of that discharged by WWTPs. With the Climatic Change long (e.g. over seasonal) dry periods appear, followed by floods and sewerage overflows activity. And summer temperature maxima increase. We deal here with rivers of Strahler order 7-8, representing basins of Vltava and Elbe upstream the confluence, and with the Czech Elbe basin as a whole.
