“…Variable effects of metals could be dependent on the induction of different antioxidant/pro-oxidant responses depending on their ability to produce ROS which was also mentioned by Barata et al, (2005). These results were also in accordance with our previous studies (Atli et al, 2006;Atli and Canli, 2010;Eroglu et al, 2015). It is also important to declare that similar pattern of subchronic Pb effects was observed on both hematological and antioxidant system including enzymatic and non-enzymatic parameters.…”

“…A freshwater fish O. niloticus is shown to be a good tolerant with a strong immune system and sensitive bio-indicator organism based on the studies suggesting the toxicity and physiological effects of several metals including Cu and Pb on this species (Almeida et al, 2002;Atli et al, 2006). Nevertheless, there is still required data showing the relation of metal toxicity with several biomarker responses to understand the physiological and biochemical role of these systems in this sensitive species.…”

This work presents the study of the effects of acute exposure to various concentrations of copper from 0.03 to 0.59 mol⋅L −1 on the metabolic activities (nitrogen and phosphorus), protein levels, catalase (CAT) enzyme activities, and the biological response malondialdehyde (MDA) in the mollusks Perna perna and Mytilus galloprovincialis. The concentrations above 0.88 mol⋅L −1 have proven to be lethal to P. perna. The results show slight disturbances of metabolism as a result of pollutant and a significant correlation between metal contamination and ammonia nitrogen levels, resulting in an increase in the latter after 48 h of M. galloprovincialis exposure to 0.59 mol⋅L −1 of copper concentrations. CAT was rapidly induced even by low concentrations of copper; MDA was increased only with low concentrations of copper in P. perna.

The contribution of decameric vanadate species to vanadate toxic effects in cardiac muscle was studied following an intravenous administration of a decavanadate solution (1 mM total vanadium) in Sparus aurata. Although decameric vanadate is unstable in the assay medium, it decomposes with a half-life time of 16 allowing studying its effects not only in vitro but also in vivo. After 1, 6 and 12 h upon decavanadate administration the increase of vanadium in blood plasma, red blood cells and in cardiac mitochondria and cytosol is not affected in comparison to the administration of a metavanadate solution containing labile oxovanadates. Cardiac tissue lipid peroxidation increases up to 20%, 1, 6 and 12 h after metavanadate administration, whilst for decavanadate no effects were observed except 1 h after treatment (+20%). Metavanadate administration clearly differs from decavanadate by enhancing, 12 h after exposure, mitochondrial superoxide dismutase (SOD) activity (+115%) and not affecting catalase (CAT) activity whereas decavanadate increases SOD activity by 20% and decreases (À55%) mitochondrial CAT activity. At early times of exposure, 1 and 6 h, the only effect observed upon decavanadate administration was the increase by 20% of SOD activity. In conclusion, decavanadate has a different response pattern of lipid peroxidation and oxidative stress markers, in spite of the same vanadium distribution in cardiac cells observed after decavanadate and metavanadate administration. It is suggested that once formed decameric vanadate species has a different reactivity than vanadate, thus, pointing out that the differential contribution of vanadium oligomers should be taken into account to rationalize in vivo vanadate toxicity.
