Abstract: 

Since hundreds of years ago, researchers have been studying the accumulation of metals in aquatic organisms` tissues and their effects on ecosystem. But in some decades before, relationship between enzymes to heavy metals has made researchers become interested in this field. Some organic and inorganic pollutions cause Oxidative stresses in marine organisms. Due to these problems bio-indicators such as mussels, barnacles and fishes can help to recognize polluted areas and the scale of polluted materials in marine organism’s tissues as a useful tool. On the other hand, in oil platforms there are heavy metals due to discharge of hydro-carbonated material and this tissue is a suitable area for assaying of relationship between heavy metals and enzymes. Accordingly, changes in superoxide dismutase enzyme in barnacle were chosen as a biomarker. For assaying of Nickel, Cobalt and Vanadium in seawater, tissue was gathered from eight stations of Bahragan area. The average amount of these metals within samples taken from barnacles was 0.4 ppm (Ni), 0.2 ppm (Co), and 0.2 ppm (V). Also analyses were assayed by Atomic Absorption. Correlation coefficient for Vanadium, Nickel and Cobalt in water samples were respectively 0.43, 0.50 and 0.56 and also in tissue -0.19,-0.15, -0.16 that assay by special kit. The only positive correlation was found between TDS and superoxide dismutase (r=0.775), while other parameters showed insignificant correlation.
