This study is focussed on evaluation of temperature effectduring frozen storage on movement of trace elements in differenttissues (exoskeleton, carapace and abdominal muscle) of twocommercially important shrimp species (Penaeusmerguiensis and Metapenaues affinis). Moreoverrelationships between total length and sex of specimens with concentration of trace elements in selected tissues were assessed. Concentrations of Cd, Cr, Cu, Fe, Mn, Ni and Znin samples were determined by ICP-AES. Only in the case of Niand Zn sex related differences could be observed. With theexception of Cu, the trace metals distributed significantlydifferent between the tissues. The only significant differencesbetween species were found in bioaccumulation of Mn. Sizedependent relationship was observed only for Ni. Associationsbetween Mn and Fe were positively and highly significant in allthe cases. The levels of all the metals in muscle of the shrimpsfrom the studied region were comparable to other world areas. MeanCu and Zn levels in edible parts of M. affinis stored at–10 °C exceeded some existing guidelines, while the concentrations at –30 °C were somewhat lower than them.  相似文献   

Effect of Glomus Intraradices on Physiological and Biochemical Traits of Wheat Grown in Nickel Contaminated Soil   总被引：1，自引：0，他引：1

This study was undertaken to evaluate the role of mycorrhizal fungi application on mitigating adverse effects of nickel (Ni) in wheat. The experiment was conducted using four levels of Ni (0, 60, 120 and 180 mg per kg of soil) and two levels of mycorrhizal fungi application (with and without Glomus intraradices). Ni stress significantly decreased total dry weight per plant and total chlorophyll. By contrast, proline, superoxide dismutase (SOD) enzyme activity, malondialdehyde (MDA), and the accumulation of Ni in the leaves and roots increased on account of Ni treatments. In addition, mycorrhizal fungi application increased total dry weight per plant and total chlorophyll as well as the accumulation of Ni in the roots. Mycorrhizal fungi application could reduce proline, SOD enzyme activity, MDA and the accumulation of Ni in the leaves. In general, the results suggest that mycorrhizal fungi application reduces the harmful effects of Ni stress in wheat.  相似文献
