Assessment of coastal pollution in Abu-Qir bay by determination of minerals and antioxidant enzymes in different tissues for Mullus barbatus


Author(s): Marwa M Mazrouh

Abstract: This study was aimed to determine the levels of minerals and antioxidant enzymes in the muscles, liver and gills of Mullus barbatus collected from Abu-Qir Bay during December (2015). These minerals were chosen because at higher concentrations there might be toxic to the fish. The mean contents of minerals were carried out using Flame Atomic Absorption Spectrophotometer (Perkin Elmer) 2280 and expressed in mg/100gdry weight. Results showed that the highest concentrations were in liver and gills while the lowest concentrations were in muscles. The mean concentrations of Zn varied from (2.15 to 3.71),Cu (2.48 to 4.76), Cd (1.34 to 2.96), Na (119.16 to 148.12), K (182.64 to 205.96), P (2.35 to 4.09), Ca (2.09 to 5.52) and Mg (2.42 to 3.43).The concentrations of minerals were identified to have the following decreasing sequence: K > Na > Ca > Cu > Zn > Mg >P>Cd. Significant differences are observed in the activity of oxidative stress at investigated organs. There is an increased in GSH content and CAT activity in liver and gills than in muscles. Mineral concentrations differences among the investigated organs were statistically significant (p<0.05) and various degrees of correlations coefficient. It can be concluded that it is necessary to make a regular analysis to observe and assess the high levels of minerals and the possible effects on the ecosystem in the Abu-Qir Bay, and using the antioxidant enzymes as environmental monitoring.
