Measurement of some heavy metals in tissues infect by intestinal worms of two kind of fishes in Al-Qadisiyah Province

The present study has been conducted in four parts of AL-Qadisiyah (Al-Diwaniyah center, Shamiya, Hamza and Afak). A sample of 945 fish of Barbus grypus and Liza abu has been examined. It was found that 205 of the Barbus grypus fish and 344 of the Liza abu were infected with parasitic intestinal worms. Some parasitic intestinal worms have been detected such as the Neoechinorynchus iraqensis in both fish types. The female paulisentus, Bothriocephalus acheilognathi were found in both Barbus grypus, Liza abu and the larva of Contracaecum spp was seen in the Liza abu and Barbus grypus type. Four heavy metals were measured. They included Cadmium, Lead, Zinc, Nickel, by means of an atomic absorption spectrophotometer issues from the a fore mentioned types of fish were measured for these heavy metals these tissues were from the liver, muscles, gills, from four districts of Al-Diwaniyah throughout the year, Cadmium registered high concentrations in autumn (12.67) Mg/ gm in the liver of the Barbus grypus. Lower concentrations of Cadmium were registered in winter (1.30) Mg/ gm in the liver of Liza abu. The Barbus grypus livers had high concentrations of lead in autumn (21.03) Mg/ gm in Hamza rivers, whereas gills of the Liza abu registered lower concentrations (6.43) Mg/gm in spring. The livers of the Barbus grypus registered high concentrations of zine in autumn which where (32.27)Mg/ gm in Hamza river while Shamiya river they dropped to 21.17 Mg/ gm in spring, It was observed that Nickel had high concentrations in the livers, muscles, gills, of both fish types, The highest of which was in autumn, the Hamza river had the highest concentrations in autumn which were (29.17,28.63,27.67) Mg/g in Barbus grypus , in spring the nickel concentrations were low in the gills of the Liza abu11.10 Mg/ gm in Shamiya river
