Res.-P >Fe-P>Al-P>Loosely-P. The variation range of pH, Eh and TOC% were 8.05-8.60, (-63)-(-83) and 1.36-7.87, respectively. The results revealed that temperature, Eh and pH had the main role in the adsorption and release of loosely-P, Fe-P and Al-P. Comparison of 25-75th percentiles of total organic carbon (1.97-2.60%) with permissible threshold showed that the sediments of Nowshahr region can be classified as moderately polluted.]]>

0.05), but the content of total ω-6 was significantly higher in farmed (17.39%) samples than wild ones (13.27%). The ratio of ω-3 /ω-6 was higher in wild sample (2.9) from farmed ones (1.75) (p < 0.05). Between wild and farmed caviars respectively, the atherogenic, (0.29, 0.28), thrombogenic (0.18, 0.21), Hypocholesterolaemic/Hypercholesterolaemic (2.45, 2.52) Polyene (1.73, 1.46) and Peroxidisability (326.86, 269.03) indexes contents had no significant differences (P>0.05). The present study indicated that the caviar from farmed Beluga like wild ones could be considered as a good food sources, besides, it has good balanced with lipid nutritional quality indices to cardiovascular prevents and finally it has important impact on protecting wild population from elimination.]]>

0.05). Alkaline phosphatase activity was only decreasing in hepatopancreas, which was significantly higher than control (p < 0.05). Lactate dehydrogenase level was not significantly different in all tissues (p>0.05). Among the antioxidant enzymes, the activity of superoxide dismutase in hepatopancreas and gills showed a significant decrease (p < 0.05) compared to control, but glutathione peroxidase had no significant difference (p>0.05). The level of glutathione S-transferase was increased only in hepatoconal tissue and in treatment 4 significantly (p < 0.05). The level of glutathione S-transferase was increased only in hepatopancreas tissue and in treatment 4 significantly (p < 0.05). Overall, results showed that shrimp exposure to high concentrations of silver nanoparticles causes oxidative damage, especially in the hepatopancrease tissue.]]>
