Abstract

DISTRIBUTION OF SOME TRACE METALS IN AL-CHIBAYISH MARSH OF PART ECOSYSTEM IN THI-QAR PROVINCE IN SOUTHERN IRAQ

Basim Y. Al-Khafaji, *Afrah A. Al-Awady, **Afaq Talib Farhood

ABSTRACT

trace metals Cd, Cu, Mn, Pb and Zn were determined in dissolved and particulate phase of the water, in addition in sediment and in the selected organs of the fish Acanthopargus latus and Cyprinus carpio collected from Chibayish Marshes, during summer / 2014. Also sediment texture and total organic carbon (TOC%) were measured. Analysis employing a Flam Atomic Absorption Spectrophotometers . The mean cocentrations of the trace metals in dissolved (ug /L) and particulate phase (ug /gm dry weight) were Cd (0.12, 13.5) , Cu (1.4, 14.25), Mn (0.36, 47), Pb (0.24, 20) and Zn (0.3, 610) respectively and those for sediment were Cd (3.5), Cu (2.75), Mn (7.5), Pb (6.75) and Zn (127) (ug /gm dry weight) respectively. The present study showed a difference in concentration of studied metal in different Organs of fish. These concentration varies from one to another and the Organs of same species showed difference in concentration of studied metals. This due to the nature and the function of the Organs and ability fish or regulating the level of the metals in their bodies during uptake and elimination processes. And the result showed that trace element concentration in muscles of two the species were in the international acceptable limits ,so it can be safety having related to this type of pollutants now days. Considered good indicator of accumulation for trace element in the water.

Keywords: Al-Chibyish marsh, fish, trace metals, water, sediment.
