EFFECT OF POLLUTION OF HEAVY METALS (LEAD, CADMIUM AND MERCURY) ON THE LEVEL OXIDATION OF MALONE DI ALDEHYDE (MDA) IN THE TISSUES CULTURE OF CYPRINUS CARPIO IN CAGES ON THE EUPHRATES

Abstract

Abstract This study was conducted during the summer of 2019, and three fish culture sites (Cyprinus carpio L.) were selected in cages on the Euphrates within Anbar Governorate, which are under the influence of industrial and human agricultural activities, Where some of the physical and chemical properties of the Euphrates water were measured in the above locations such as temperature, pH, turbidity and total dissolved solids and they were generally within the normal limits, and the level of oxidation was examined (MDA) In the tissues of the fish under study, as the results of the current study showed that the Ramadi site showed a significant effect at a significant level (P≤0.05) Outperforming the Fallujah and Al-Baghdadi sites, the sites examined took the descending order of the value of Malone Day aldehyde (AL Ramadi <Al-Baghdadi <Fallujah). As for the members, the liver recorded the highest value of Malone di-aldehyde at Al-Ramadi site with a value (0.2418 mg MDA / gm liver). The members took the descending order in relation to the value of Malone di-aldehyde (liver <gills> muscles)
