The Determination of Some Pollution Parameters, Water Quality and Heavy Metal Concentrations of Aci Lake (Karapinar/Konya, Turkey)

Abstract

Water quality parameters were measured in Acı Lake. The measurements were carried out in water samples taken from five different stations over ten months. According to the results of the analyses done on the samples of water, without taking into consideration the differences of seasons and stations, the average annual values of heavy metal concentrations for Cr, Cu and Ni were found to be 0.10 mg/l, 0.11 mg/l and 0.19 mg/l dry weight, respectively. Surprisingly, Co and Cd metals were not detected at any station or at any season. Other water quality parameters, namely pH, turbidity and nitrate, fall in the intermediate value range for these measures. The comparisons of the measured parameters and the metal concentration with the water quality index show that the water quality of Acı Lake prevents the water being used as irrigation water due to high salt levels. ZUSAMMENFASSUNG: Bestimmung einiger Verunreinigungsparameter, derWassergüte und der Schwermetallkonzentrationen des Aci-Sees (Karapinar/Konya, Türkei).Im Aci-See wurden die Gewässergüteparameter gemessen. Die Wasserproben wurden innerhalb von zehn Monaten an fünf Probestellen entnommen. Entsprechend den Ergebnissen der untersuchten Wasserproben -ohne Berücksichtigung der jahreszeitlichen und der standörtlichen Unterschiede-wurden die jährlichen Mittelwerte des Schwermetallgehaltes von Cr, Cu und Ni mit jeweils 0,10 mg/l, 0,11 mg/l und 0,19 mg/l Trockengewicht ermittelt. Überraschender Weise wurden die Schwermetalle Co und Cd innerhalb des Untersuchungszeitraumes an keiner der Probestellen vorgefunden. Messungen der pH Werte, der Trübung und Nitrate wurden als zusätzliche Gütewerte hinzugefügt. Der Vergleich der gemessenen Parameter und der Schwermetallkonzentration mit dem Gewässergüte-Index zeigen, dass das Wasser des Aci Sees aufgrund seines hohen Salzgehaltes für Bewässerungszwecke nicht verwendet werden kann.REZUMAT: Determinarea parametrilor de poluare, calitatea apei și concentrația metalelor grele din lacul Acı (Karapinar/Konya, Turcia).Parametri de calitate ai apei au fost măsurați pentru lacul Acı. Măsurătorile, au fost realizate pentru probe de apă din cinci stații pe parcursul a zece luni. Rezultatele arată, fără a lua în considerare diferențele sezoniere și stațiile, că valorile medii anuale a concentrațiilor de metale grele precum Cr, Cu și Ni sunt următoarele: 0,10 mg/l, 0,11 mg/l și 0,19 mg/l din substanța uscată. Nu au fost observate metale precum Co sau Cd în nici un sezon sau stație. Pe lângă acestea, pH-ul, turbiditates și o concentrația de nitraţi au fost măsurate. Comparația concentrațiilor măsurate cu indicele de calitate al apei arată că apa din lacul Acı nu poate fi acceptată pentru irigare datorită nivelului ridicat de săruri.

Study of the Water Quality of a Tropical Reservoir

“…In this study, the Ecological Risk Index (ERI) was used as a fast and practical tool for environmental risk assessment in ALMD. This methodology is proposed by Håkanson [19] and suggests the classification of contamination in a waterbody and the identification of the toxic substances in order to take actions for the control and mitigation of this contamination [40][41][42]. The Ecological Risk Index is based on the Equations (6) and 7:…”

Acı Göl ve Meke Gölü’ nün (Konya / Türkiye) Bazı Su Kalitesi Özellikleri

“…Acı Lake, which is volcanic-based and a salty water source, is an important habitat for birds and other creatures (Akköz 2017a). Meke Lake, which came into existence as a result of the accumulation of water in an inactive volcano crater, and which includes various islets inside itself, has been added to the RAMSAR pact about the international protection of the aquatic places issue, at 21 June 2005 (Akköz 2017b).…”
