“…These results partially matched those reported for limpet Nacella magellanica by Malanga et al (2007), where SOD was seasonally independent but ascorbyl radicals increased with temperature. However, opposite results with higher activity of SOD in winter have been reported for M. edulis chilensis , M. galloprovincialis (Santovito et al, 2005) and Perna viridis (Verlecar et al, 2008). Great variability in the response of several antioxidant parameters in populations of aquatic organisms from polluted and unpolluted areas has been observed in other field studies.…”

Seasonal variations of trace metals did not appear to influence those of biochemical parameters, which generally showed an opposite trend with higher enzymatic activities in summer when trace metal concentrations were lower. Organisms from Punta Cuevas (control site) showed higher induction of reactive oxygen species production than those from both considered impacted sites, suggesting the possibility of some biochemical adaptation in organisms or a higher modulation of environmental and physiological factors on antioxidant responses than levels of trace metals. This study, which is the first in the area in this matter, showed that seasonal variations of potential biomarkers should be incorporated into interpretation of long-term biomonitoring studies in this marine coastal ecosystem.

“…Opposite results were found for ROS, which showed significant relationships with the same environmental parameters but inversely correlated. In this sense, it is known that trace metals are able to promote the intracellular formation of ROS in mussels (Verlecar et al, 2008;Vlahogianni and Valavanidis, 2007).…”

“…It is most likely that an increase in superoxide anions stimulated the consumption of SOD, and that CAT activity was induced by H 2 O 2 formation (Ren et al, 2013). The observed decrease in GR activity may also indicate increased ROS levels, since the role of GR is to regenerate the antioxidant glutathione from GSSG (Verlecar et al, 2008).…”

“…Previous studies that found the inducement effects of heavy metals on antioxidant enzyme activities in aquatic organisms such as goby and mussel. 47 In POX activity of metal treated Spodoptera litura midgut tissue shows significantly increased activity in Cd 0.50 mg Cd 0.3 mg, Pb 4.8 mg, Pb 0.48 mg, as compared to control. However in Cd 0.44 mg and Pb 9.6 mg, concentration shows significantly decreased as compared to control, but same activity metal treated fat body tissues shows significantly increased activity in Pb 4.8 mg, Pb 0.48 mg, and Pb 9.6 mg as compared to control.…”

Introduction: Oxidative stress in insects may result from an imbalance of oxidants and antioxidants under a significant impact of metals. Reactive oxygen species (ROS), such as superoxide, hydrogen peroxide, and hydroxyl radical, are generated from normal metabolic processes in all oxygen-utilizing organisms. In the present study was designed to the impact of heavy metal (Cadmium and Lead) toxicity and its free radical scavenging enzymes in Spodoptera litura larvae. Methods: Heavy metals were administered using artificial diet method having different concentrations. The metal toxicity was observed after 24 and 48 hrs post treatment. In antioxidant parameters were SOD, CAT, POX, GST, LPO, ACP and AKP were assessed. In additionally metal accumulation analysis using ICP-MS. Results: In particular, after exposure to diets containing environmentally relevant concentration (Cd 0.3 mg, Cd 0. 44 mg, Cd 0.50 mg or Pb 0.48 mg, Pb 4.8 mg, Pb 9.6 mg) at 48 hrs changes in the activity of antioxidant enzymes were measured in larvae. The results showed that compared with control, the based on concentration significantly increased of antioxidant enzymes activities. In ICP-MS analysis results shows based on the concentration Pb 9.6 mg, 325.61 ppm/mg -1 and Cd 0.44 mg, 36.5 ppm/mg -1 will be increased. Conclusion: In conclusion antioxidant systems of S. litura were altered by Cd and Pb exposure as determined by measuring in the enzymes activities. All of Cd and Pb result in strong oxidative stress and toxicity to S. litura larvae. Based on the results we suggest that metal toxicity and metal accumulation of insects influenced by Cadmium chloride and Lead nitrate in S. litura larvae.
