Quality Assessment of Some Freshwater Resources Located in Bucharest and Surrounding Areas I. Water Quality Assessment of Herastrau, Pantelimon and Mogosoaia Lakes

Abstract

The quality assessment of the aquatic environment from some freshwater resources situated in Bucharest and Ilfov County - Romania has been performed in an extended study and data obtained will be presented in several papers. This first paper presents a case study on water quality assessment of the Mogosoaia, Herastrau and Pantelimon Lakes, lakes built on the Colentina River. Two water and sediment sampling campaigns were conducted in the summer and autumn 2016, 29 specific parameters were determined for water samples and heavy metals content for sediment samples. The obtained results for water samples allowed the classification of lakes water in quality classes and the heavy metals values for sediments were compared to the standards of chemical quality, according to the national legislation M.O. 161/2006. Furthermore, for an overview of water quality, the Water Quality Index (WQI) method was used, where the indicators were grouped into two categories: the first category took into account 18 quality parameters (WQI-1) and the second considered heavy metals content (WQI-2).

Quality Assessment of Some Freshwater Resources Located in Bucharest and Surrounding Areas II. Water quality assessment of Arges and Dambovita rivers

“…The Part I of this work related a case study on water quality assessment of the Mogosoaia, Herastrau and Pantelimon Lakes, built on the Colentina River which is the tributary of the Dambovita River [1]. This paper is the Part II which presents the water quality assessment of Arges and Dambovita rivers at their confluence area through the physicochemical parameters according to national current regulations.…”

Quality Assessment of Some Freshwater Resources Located in Bucharest and Surrounding Areas. III. Case Study: Trophic Status Assessment of Mogosoaia, Herastrau and Pantelimon Lakes

“…Part I in the series of study for quality assessment of some freshwater resources located in Bucharest and surrounding areas [1] presents the quality assessment for Mogosoaia, Herastrau and Pantelimon lakes by employed various multi-parametric indices and the class-based evaluation system [21] for water and sediment quality. Part II of the mentioned study [2] extends the quality evaluation on the Arges and Dambovita Rivers, components of the overall hydrographic region of the Colentina River on which the Mogosoaia, Herastrau and Pantelimon lakes are formed.…”
