Comparative study on the accumulation of heavy metals in different organs of tench (Tinca tinca L. 1758) and plerocercoids of its endoparasite Ligula intestinalis

Abstract

Concentrations of heavy metals (Cu, Fe, Zn, Mn, Cr, Pb and Cd) in some organs of tench and tissues of its parasite found in Kovada Lake (Turkey) were analyzed using atomic absorption spectrophotometry and subsequently compared with the data from sediments and water. Only Cu, Fe, Zn and Mn were detected in water, sediment, plerocercoids of Ligula intestinalis and fish samples, while levels of Cr, Pb and Cd were below the detection limits. Four elements were found at higher concentrations in the plerocercoid than in different fish tissues (muscle, liver and gill), being 1.6-37.4 times higher than that measured in muscle, liver and gill. Significant positive (for Cu) and negative (for Fe, Zn and Mn) correlations were found between the quantity of heavy metals in water and tissues of L. intestinalis plerocercoids while there were significant positive (for Cu and Zn) and negative (for Fe and Mn) correlations between the quantity of heavy metals in bottom sediment and tissues of L. intestinalis plerocercoids. Cestodes were found suitable to reflect the amount heavy metals in sediments, providing more reliable information about the actual pollution of the reservoirs.

Determination of heavy metal levels in water, sediment and tissues of tench (Tinca tinca L., 1758) from Beyşehir Lake (Turkey)

“…Karadede and Ünlü (2000) investigated concentrations of heavy metals in Atatürk Dam Lake (Turkey) and found following concentrations (in mg l −1 ): as 0.025-0.22 for Cu, <DL-0.062 for Fe, 0.0064-0.197 for Zn, 0.0039-0.0041 for Mn. The heavy metal levels of water in Beyşehir Lake were higher than compared to the metal levels in Atatürk Dam Lake (Karadede and Ünlü 2000) with the (2000) g Tekin-Özan and Kır (2005) h Al-Saadi et al (2002) i Below Detection Limit Karadede and Ünlü (2000) c Tekin-Özan and Kır (2005) d Al-Saadi et al (2002) exception of Zn in some seasons, and lower than the metal levels of water in Kovada Lake (Tekin-Özan and Kır 2005) and Habbaniya Lake (Al-Saadi et al 2002). It is clear that Beyşehir Lake doesn't have an important pollution source in terms of heavy metals like Habbaniya Lake.…”

“…In comparison,, Fe concentrations were the highest and Cu were the lowest those recorded in the Atatürk Dam Lake (Karadede and Ünlü 2000) and Kovada Lake (Tekin-Özan and Kır 2005). Iron is generally the most abundant metal in all of the reservoirs because it is one of the most common elements in the earth's crust (Usero et al 2003.).…”

Pomphorhynchids are infrequent parasites of amphibians.…”
