“…Some phenols are formed during natural processes. Phenols were reported as harmful ecotoxins having genotoxic, mutagenic, hematotoxic, and carcinogenic nature to both fish and human (Pulkrabová et al 2007;Havelková et al 2008;Dû-Lacoste et al 2012). Compared to the control, a significant amount of heavy metals (P < 0.01) was determined in the muscle tissues of the fish tested from the highly/mildly polluted sites (Fig.…”

The eastern and southern parts of the Faisalabad city produce considerable quantities of industrial and municipal pollutants, much of which is drained into the River Chenab, reducing the productivity of fauna and flora in the river. This study was aimed to determine whether cysteine is useful as a biomarker of exposure to polluted fresh water. The amino acid profile of fish muscle was analyzed by paper chromatography in Cirrhinus mrigala and Labeo rohita from the River Chenab to determine habitat related variations due to the pollution from industrial and domestic sources. C. mrigala showed higher level of metal contamination in muscle tissues for Sn, Cr, Pb, Zn, Mn, Cu, and Cd when compared to L. rohita. Both fish species collected from polluted areas of the river Chenab showed significantly (P < 0.01) higher levels of metals in comparison to upstream and farmed fish. Farmed C. mrigala showed cysteine concentrations in the muscle tissue as 22 ± 1 mg/g dry weight, but concentrations increased to 45 ± 2 mg/g dry weight for fish from a mildly polluted section of the river, and further increased to 83 ± 2 mg/g dry weight in more heavily polluted sections. Cysteine concentration in farmed L. rohita was detected as 28 ± 2 and 25 ± 4 mg/g dry weight, respectively for farmed fish and fish from a mildly polluted section of the river, and then increased to 94 ± 3 mg/g dry weight for fish from highly polluted water. C. mrigala from a mildly polluted area of the river also had higher levels of cysteine in the muscle, along with increases in aspartic acid, glutamic acid, and alanine. Elevated concentrations of cysteine seem to be associated with a threat to these fish species in polluted sections of the river, and thus may be used as a biomarker.

“…The presence of organic pollutants in fish muscle and their relation to specific biomarkers were also determined by Siroka et al [66] where, the GST is an important intracellular enzyme of the second stage of xenobiotic metabolism. Its main function is to catalyze the conjugation of glutathione and electrophilic substances of exogenous origin that might be one of etiological factors of carcinogenesis and development of degenerative diseases [67].It is used as a biochemical marker of aquatic environmental contamination with exogenous substances [68]. The liver and muscle tripeptide glutathione concentration of Siganusrivulatus collected from El-Mex Bay was increased by 73.63% and 77.54%, respectively compared to its corresponding value collected from Matrouh coast ( Figure 6 and Figure 7, respectively).…”

The main objective of this paper is to understand the importance of biochemical biomarkers in assessing marine pollution by Polychlorinated biphenyls (PCBs) and Pesticides. Methods: The oxidative stress and antioxidant response as well as ultrastructural changes of both liver and muscle tissues of Siganusrivulatus collected from El-Mex Bay as a polluted region and Marsa Matrouh as a control region far from land-based sources of pollution have been investigated by using standard methods. In general, the results cleared out that El-Mex Bay was much more polluted by polychlorinated biphenyls (PCBs) and pesticides compared to Matrouh area. The concentration range of total polychlorinated biphenyls (PCBs) and pesticides in sediment samples collected from Matrouh coast was 16.29-32.58 ng/g, dry weight and 107.62-149.11ng/g, dry weight, respectively. On contrast, the range in sediment samples collected from El-Mex Bay was 217.12-255.33 ng/g, dry weight and 663.73-778.7ng/g, dry weight, respectively. Biomarkers studies revealed that the induction of antioxidant systems in response to oxidative stress and the increase in lipid peroxidation in fish collected from the polluted area were good indicators for the pollution load" in the present study. On the meantime, the present study revealed that ultrastructural changes serve as a biomarker of stress in aquatic environment. Moreover, the results suggested that chemical pollution, on the other hand, is capable of inducing morphological alteration in liver of fish collected from polluted area.

Stressful environmental conditions are ecological force in modulating adaptive responses of fish populations in aquatic ecosystems with a large number of biochemical and physiological effects associated with increased fluxes of oxyradicals. This study was aimed to examine the impacts of oxidative stress and histological changes in organs of Chrysichthys nigrodigitatus from Ologe and Badagry lagoons. Biomarkers such as biochemical markers [malondialdehyde (MDA) and superoxide dismutase (SOD) and catalase (CAT) and glutathione (GSH)] and histological marker were analysed in C. nigrodigitatus using standard protocols. The biochemical response of C. nigrodigitatus indicated that there was significant increase (p < 0.05) in the activities of MDA and SOD, as well as CAT and GSH in the gill, liver and muscle of the fish samples of both lagoons. The CAT activities in the muscle negatively correlated with MDA in gill (p < 0.05, r =-0.848) in Ologe lagoon. The histological changes in the gill exhibited mild epithelial lifting, fusion of secondary lamellae; inter-lamella hyperplasia, desquamation and necrosis of secondary lamellae. Furthermore, the hepatic tissue showed disseminated moderate microvesicular vacuolation of hepatocytes, moderate vascular congestion and mild presence of eosinophilic fluid within the interstitial. The renal tissue also showed mild hemorrhagic lesion, mild moderate ballooning degeneration of renal tubules and thickened blood vessel. The study provides baseline information that can be useful for effective biomonitoring and future comparative studies of oxidative stress and histomorphological changes in aquatic biota from polluted coastal ecosystems.
