present in the environment could constitute a hazard to food security and public health. These can be accumulated in aquatic animals such as fish.
Objective: In this study, selected heavy metals: Copper (Cu), Nickle (Ni), Chromium (Cr) and Iron (Fe) were evaluated in commercial canned fish products (Sardines) that are commonly consumed in Iraq. The canned fish (Sardine) which studied were Yacout Sardine (Morocco), Marina Sardine (Tunisia), Silver Sardine (Morocco) and Salsa Sardine (China).
Methods: Prospective study was done in Baghdad from January to June 2016 . 40 samples of four different foreign brands (10 samples for each brand were obtained): Yacout Sardine (Morocco), Marina Sardine(Tunisa), Silver Sardine (Morocco) and Salsa Sardine (China) of canned fish (90 g cans) were analyzed for their content of Cu, Ni, Cr and Fe. Atomic absorption spectroscopy technique was used for determination of metals under study.
Results: Mean levels of Cu in four types of canned sardine were 0.7±0.03 μg/g in Yacout canned sardine, 0.9±0.0303 μg/g in Marina canned sardine, 2.1±0.367 μg/g in silver canned sardine and 1.0±0.41 μg/g in Salsa canned sardine, while mean levels of Ni in four samples were 0.14±0.043 μg/g, 0.12±0.035 μg/g ,0.12±0.055 μg/g and 0.14±0.0285 μg/g .Also mean levels of Cr in same four samples were 0.1±0.0332 μg/g, 0.08±0.02 μg/g, 0.1±0.0245 μg/g, 0.11±0.0274 μg/g. and mean levels of Fe in four samples were 21±1.685 μg/g , 25±1.1 μg/g , 20±1.886 μg/g and 30±0.831 μg/g respectively
Conclusion: analytical data obtained from this study shows that the metal concentrations for the types of canned sardines except Fe were generally within the Environmental Protection Agency in United States of America (U.S.EPA), Food and Agriculture Organization (FAO),World Health Organization(WHO) and Food and Drug Administration in United States of America (U.S.FDA) recommended limits for canned fish and do not cause any risk for the local consumers, but contamination of Fe in majority of canned sardines samples may cause risk for the consumers.
Abstract: The M(II) complexes [M2(phen)2(L)(H2O)2Cl2] in (2:1:2 (M:L:phen) molar ratio, (where M(II) =Mn(II), Co(II), Cu(II), Ni(II) and Hg(II), phen = 1,10-phenanthroline; L = 2,2'-(1Z,1'Z)-(biphenyl-4,4'-diylbis(azan-1-yl-1-ylidene))bis(methan-1-yl-1- ylidene)diphenol] were synthesized. The mixed complexes have been prepared and characterized using 1H and13C NMR, UV/Visible, FTIR spectra methods and elemental microanalysis, as well as magnetic susceptibility and conductivity measurements. The metal complexes were tested in vitro against three types of pathogenic bacteria microorganisms: Staphylococcus aurous, Escherichia coli, Bacillussubtilis and Pseudomonasaeroginosa to assess their antimicrobial properties. From this study shows that a

The effects of gamma irradiation on structure of HgBa2Ca2Cu2.4Ag0.6O8+δ samples were characterized using X-ray diffraction. It was concluded that there effect on structure by gamma irradiation. Scherrer, crystallization, and Williamson equations were applied based on the X-ray diffraction diagram and for all gamma doses, to calculate crystal size, strain, and degree of crystallinity. I
