Water quality analysis in the upper part of Litava river basin focused on nitrogen compounds contamination

Popis výsledku v původním jazyce

Nitrogen and phosphorus belongs among essential elements and their compounds play key role in cycles of matter. However, over-enrichment with these elements in surface water is a widespread problem resulting for example in eutrophication, methemoglobinemia caused by nitrates and fish poisoning by toxic ammonium ions. The evaluation of annual development of water pollution by nitrogen compounds in the upper part of Litava basin is the main aim of this paper. Twelve sampling profiles have been determined in the interest catchment placed east of Brno - eight directly on Litava stream and four on its main tributaries. The monitoring of selected water quality indicators (total nitrogen, nitrate nitrogen and ammonium nitrogen) was performed since June 2016 to May 2017. Results has been compared with valid legislation - ČSN 75 7221 and Government order No. 401/2015 Coll., as amended and clearly confirmed influence the ammonium nitrogen pollution of water quality in Litava river. The limit specified in the Government order limit was exceeded in almost all profiles. This pollution is caused by point sources of pollution, especially municipality.
