Assessment of water quality in the Prut River- tributary of the Danube River, according species indicators of phytoplankton
Journal Title: Scientific Annals of the Danube Delta Institute - Year 2016, Vol 22, Issue
Abstract
The Prut is a 953 km (592 mi) long river in Eastern Europe. In part of its course it forms Romania's border with Moldova and Ukraine. The Prut flows southeast eventually joining the Danube river near Reni, east of Galați. Quality of Prut river are influenced by antropicals and naturals factors. The Prut River quality monitoring system includes observation at 8 points. Phytoplankton is one of the most important elements in determining the quality of aquatic ecosystems. The basic indices upon which phytoplankton is examined are: species, quantity and biomass. Change in quality of water leads to the change in above mentioned indices. Samples of phytoplankton were collected in 250 ml. flasks were fixed in 4% of the alignment solution of formalin or Lugol's iodine solution, transported to the laboratory, where processed by settling. First, the samples stand for 3-4 weeks, then they thickened up to 30 ml. Then 0.1 ml. condensed sample was placed on a countable glass with glycerol and dried. After this sample was studied under a microscope to determine the species and varieties of algae, the counting numbers and biomass. The components of phytoplankton was made up of species that belong to: Cyanophyta, Bacillariophyta, Chlorophyta, Euglenophyta and Dinophyta, with predomination Bacillariophyta. To assess the water quality are used the method of indicators Pantle and Bukk in a change Sladecek. Quality of water depends by location points. The average values are calculated for the saprobic indices at the analyzed sections indicated that 5 sections of Prut river may be classified as Class II quality "good" and at 6 sections as a Class III (water is moderately polluted).
