Analysis of Major and Trace Metal Levels in Kashar Lake, Artificial Lake of Tirana, Farka Lake, and Statistical Data Analysis

This study aims to determine the presence and concentration level of major metals and trace elements in the three main artificial lakes of Tirana, namely Kashar Lake, Tirana Artificial Lake, and Farka Lake. The water samples were collected from three different stations on each lake during April 2019. The concentrations of the metals, Ag, Al, As, Ba, Be, Ca, Cd, Co, Cr, Cu, Fe, K, Na, Mg, Mn, Mo, Ni, Pb, Sb, Se, Tl, V, U, Zn, were determined using the ICP-MS method. These concentrations were then compared to EU standards. The results showed that metal concentrations in the water samples were lower than the maximum concentrations allowed by environmental quality standards. Using statistical methods, we estimate the relationships between the metal levels in samples collected from different stations in different lakes. Statistical analysis showed no significant differences in metal concentrations between the different stations and lakes.
