Compare the bioaccumulation of heavy metals Liza abu (Liza abu) and yellow fin seabream (Acanthopagrus latus) Bahmanshir River in summer and winter

The study in 1393 to determine the heavy metals mercury , cadmium , lead , cobalt and vanadium in the muscles of two species Liza abu (Liza abu) and yellow fin seabream (Acanthopagrus latus) Bahmanshir River was conducted in summer and winter . Amounts of heavy metals by atomic absorption spectrophotometry Perkin Elmer 4100 took place with the help of devices.Analysis of the data was analyzed with the help of software SPSS17 help of means and analysis of variance (ANOVA One-way) were compared with each other . The results showed that the highest levels of mercury , cadmium and cobalt in Yellowfin Seabream in the summerThe highest level of lead in Liza abu in summer and in winter the highest concentration of vanadium in Yellowfin Seabream , respectively. The lowest mercury, lead and cobalt were measured in Liza abu in winter . Also the lowest amount of cadmium and vanadium in Liza abu in summer. The mercury and vanadium in muscle Liza abu and yellow fin seabream was lower compared to the threshold of global standards ,But the amount of lead and cadmium were higher than the standard limit . In general, the amount of mercury, lead, cobalt and cadmium in both species was in summer than winter , but the concentration of vanadium in winter than summer .
