Penconazole is a widely used fungicide to control critical fungal diseases of crops. This study aimed elucidate the effects PEN exposure, for 96 h, on fatty acids composition, redox status, and histopathological injuries in Ruditapes decussatus gills under different concentrations (4, 40, 400 µg/L). Compared group, our results showed an increase saturated monounsaturated acids. However, levels polyunsaturated were diminished, mainly those eicosapentaenoic, docosahexaenoic, arachidonic upon...
Widespread use of pesticides in agriculture has the potential to harm non-target creatures diffusely and contaminate aquatic habitats through leaching runoff events. Triazoles are among fungicides used extensively worldwide due their efficacy against fungal crop diseases broad spectrum action. In this study, impact Topas on antioxidant defence system, fatty acid composition histopathological injuries was experimentally examined under three concentrations (4, 40, 400 µg L-1) over 96 hours...
The aim of this study is to elucidate the toxicity induced by PbCl2, administered in graded doses (1; 2.5; 5 mg/L), redox state, fatty acid composition and histological structure Mactra corallina digestive glands. Our findings showed a progressive accumulation Pb M. glands all treated groups. After days treatment with an increase H2O2, MDA, PCO, GSH, NPSH MT levels was observed Moreover, activities antioxidant enzymes, such as GPx CAT, increased while SOD activity decreased groups,...
The bivalve Venerupis decussata has been proposed as a sentinel species for assessment of lagoon water. Our study aimed to evaluate the spatial and temporal variation oxidative stress biomarkers, metal content DNA damage in digestive gland collected seasonally from contaminated (BOUGHRARA “L2”) comparatively cleaner ( GHAR EL MELH “L1”) lagoons. Trace contents (Cu, Pb Cd) at polluted site were 1-2 folds higher compared control showed maximum especially during summer spring seasons. current...
Lead (Pb) is one of the most toxic heavy metals that affect physiological status aquatic organisms. The present investigation evaluated possible effect lead chloride (PbCl2) on biomarkers responses, DNA damage and histological alterations in Venus verrucosa gills digestive gland. Three concentrations PbCl2 (D1:1µgL−1, D2: 10µgL−1 D3: 100µgL−1) were chosen for V. exposure during six days. At end trial, it was found Pb tended to accumulate both gland a dose-dependent manner. However, gill...
The present study aimed to compare the nutritional quality of three fish species (Sparus aurata, Sarpa salpa, and Mullus barbatus) collected from Bizerte lagoon (South Mediterranean coasts). Proximate composition, fatty acids indices were determined. Results showed that follows this trend: S. aurata > salpa M. barbatus. had significantly higher protein content (16.02 ± 2.01 mg/g ww), glycogen level (1.08 0.16 lipid (8.47 0.96 ww) which are rich in omega-3 (47.34%). Total Fatty Acid (TFA)...
Acrylamide (ACR) is among the most deleterious pollutants in environment and presents a serious risk to humans ecosystems. The purpose of this study was assess its effects when administered at different concentrations (5, 10 20 mg L–1) evaluate antioxidant status gills Mactra stultorum. Our results showed, after five days treatment, an increase malondialdehyde (MDA), lipid hydroperoxides (LOOH), advanced oxidation protein products (AOPP), reduced glutathione (GSH), ascorbic acid (Vit C)...
The aim of this study was to analyze the biochemical alterations in gills Venus verrucosa under exposure for 6 days three doses lambda-cyhalothrin (λ-cyh) (100, 250, and 500 µg L −1 ). Malondialdehyde, lipid hydroperoxide, hydrogen peroxide levels treated groups increased. λ-Cyh significantly increased protein carbonyl reduced glutathione all groups. Moreover, activities superoxide dismutase peroxidase were In our study, polyunsaturated fatty acid (FA), omega-6, eicosapentaenoic (C20:5n-3),...
Bivalves are known to exhibit wide morphological variations, which closely linked their ecology and reproductive activity. Therefore, the study of growth is necessary model population dynamics, which, in turn, crucial support exploitation management stock. The current aimed analyze shell variations bivalve Ark Arca noae collected monthly from Bizerte lagoon (northern Tunisian coasts) October 2013 September 2014. Allometric relationships established between linear variables (shell length...
In the current investigation, we evaluated biological consequences of trace elements contamination in two Tunisian gulfs (Gabes gulf and Tunis gulf) on blue swimming crabs hepatopancreas (Portunus segnis). The concentrations three (cadmium, copper, lead) P.segnis were evaluated. Additionally, acetylcholinesterase (AChE), metallothioneins (MTs), hydroxide peroxidase (H2O2) advanced oxidation protein products (AOPP) levels, chosen as measurements to evaluate environmental effects crabs’...
Acrylamide (ACR), organic compound, has been widely used owing to its broad spectrum of chemical and industrial applications. This study aims at evaluating the response antioxidant defense system, fatty acid composition histopathological aspect in respiratory trees Holothuria forskali against ACR exposure under laboratory conditions. Holothuries were exposed 5, 10, 20 mg L-1 concentrations for 5 days. A significant increase n-6 polyunsaturated acids levels especially arachidonic (ARA,...
