Abstract

In this research, the results of a hydro-chemical study of Lake Kopa in Kazakhstan are described, in the
context of the regional geography and aggravating ecological problems of the lake. Besides analyzing
the concentrations of all major ions, heavy-metal ions and other pollutants, their vertical and
horizontal distribution were also assessed. Moreover, water pollution indices (WPI) were calculated
for individual ions, classes of pollutants, and total pollution, revealing serious overload of human-
induced pollution within the lake’s ecosystem. Concentrations of major ions and WPI were monitored
over 2009-2013 period, revealing a distinct seasonal pattern and a multi-year periodicity in respect to
the measured parameters. In addition, studying ion exchange between lake water and bottom
sediment showed complex non-equilibrium processes besides leaching out Ca2+ and its exchange for
Na+.

Kopa Gölü'nün yüzey suyu ve yatak sediment kalitesinin belirlenmesi

Abstract

Bu araştırmada, Kazakistan'ın Kopa Gölü'nde yapılan hidro-kimyasal çalışmanın sonuçları gölün
bölgesel coğrafyası ve ciddileşen ekolojik sorunları bağlamında anlatılmıştır. Tüm majör iyonların, ağır-
metal iyonlarının ve diğer kirleticilerin yoğunluklarının analiz edilmesi yanında, bunların dikey ve düşey
dağılımları da irdelenmiştir. Bununla beraber, su kalitesi indisleri (water quality indices-WPI)
kullanılarak her bir iyon, kirlilik sınıfları ve toplam kirlilik üzerinde yapılan hesaplamalar, göl
ekosisteminde insan-kaynaklı ciddi bir fazla yük kirliliği olduğu ortaya çıkarmıştır. Majör iyonların
konsantrasyonları ve su kalitesi indisleri (WPI) 2009-2013 periyotu boyunca izlenmiş ve ölçülen
parametreler için belirgin bir mevsimsel desen ile çok yıllık periyodiklik olduğu açığa çıkmıştır. Ayrıca,
göl suyu ve yatak sedimenti arasındaki iyon alış-verişinin araştırılması, Ca+2'un yıkanması ve Na+ ile
değişimi yanında karmaşık dengesizlik süreçleri de göstermiştir.
