Abstract: In this study, we quantified bioaccumulation of lead and copper in gill, liver and muscle of three length groups (A, B and C) of Euryglossa orientalis and sediments from the Hendijan Seaport at South coastal of Iran from October 2006 to July 2007, seasonally. The concentrations of heavy metals were determined by using flame atomic absorption spectrophotometry (FLAAS) after wet digestion method. The average sediment concentration was taken into account for metal exposure: 25.63 mg Pb kg-1 and 12.79 mg Cu kg-1. No significant differences were found between different seasons (p>0.05). Concentrations of Pb and Cu in the liver, gills and muscle were significantly different (p<0.05). Muscle, generally, accumulated the lowest levels of metals in every season and also the highest metal concentrations were observed in the liver (386.72 ± 11.72 mg Cu kg-1) and gills (14.97 ± 0.22 mg Pb kg-1) in summer. The results showed that the metal accumulation in summer season was higher than in the other seasons and also in a group was higher than other groups in all seasons. Generally, there were significant seasonal changes for Pb and Cu concentrations in all tissues (p<0.05) and concentrations of Pb and Cu in three groups were significantly different (p<0.05). These results suggest that Cu-liver and Pb gill accumulation can be good environmental indicators of metal stress in Euryglossa orientalis.
