“…Catalase is one of the first enzymes proposed as an effective biomarker for oxidative stress and involved in the hydrolysis of hydrogen peroxide (Jebali et al, 2007). In the present study, maximum catalytic activity was observed in the mantle tissue followed by the foot, abductor muscle, gonads and gills in control.…”

In recent decades, pollution of freshwater and riverine ecosystems is indorsed to heavy metals contamination. Among various causes, heavy metals are the most concern. Many aquatic organisms have the ability to inhabit in contaminated environments, due to their defense mechanisms that allow detoxification, excretion, anti-oxidant protection and stress response. Lamellidens marginalis have the potential to accumulate the heavy metals. In the present study, the mussels were exposed to 1, 5, 10 and 15 ppm concentration of mercuric chloride for 96 hrs. Enzymatic and antioxidant parameters including catalase (CAT), superoxide dismutase (SOD), lactate dehydrogenase (LDH), hydrogen peroxide (HP) and lipid peroxidation (LPO) levels were used as effective criteria. All the parameters showed responses in gills, abductor muscle, mantle tissue, gills and gonads with exposure to HgCl 2 . Collectively, these parameters could be used as biomarker for heavy metals contamination in aquatic system using L. marginalis.

“…An increase of the enzyme activity with copper concentrations was reported by Roméo et al [48] in transplanted mussels from clean water to stations of Nice and Cannes bays. Jebali et al [49] noted in clam Ruditapes decussatus a higher CAT activity in the gills and the digestive glands, in relation to pollutants presence.…”

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.

“…Decreased CAT activity has also been re ported in mice dwelling at sites contaminated by toxic metals (Montes-Nieto et al 2007). It is noteworthy, however, that other investigators have found higher CAT activity in clams and worms from BIZ and from sites near Sfax than at control sites (Jebali et al 2007, Banni et al 2009b, Bouraoui et al 2010.…”

Biological effects of pollutants were studied in Carcinus maenas crabs from 3 polluted sites (Bizerte, Teboulba, Gargour) along the Tunisian littoral zone using biochemical biomarkers. A metal contamination gradient was found, Bizerte standing out as the most metalpolluted area. Gargour animals nonetheless showed higher oxidative stress responses, such as gluta thione reductase and 6-phosphogluconate dehydrogenase activities, as well as malondi aldehyde (MDA) levels in gills. The gills showed higher lipid peroxidation than did the digestive gland, in keeping with their respiratory role. Animals were also exposed for different periods to 2 model pollutants, cadmium and chlorpyriphos-ethyl. Although cadium induces oxidative stress, mainly in gills, thus increasing lipid peroxidation, principal-component analysis indicated that metal content in sediments and crabs from in-field monitoring does not fully correlate with oxidative stress biomarker responses. Catalase and MDA were the most sensitive biomarkers, and gills the most responsive organ. A lower catalase content in gills was linked to higher MDA levels.
