Abstract

The environment of the Lavan Island has been suffered from the storage and production of crude oil, and also from ballast water. In contrast, the Hendourabi Island is away from the petroleum industries and hence ballasts water. Apparently, marine biota of the Hendourabi Island are less stressed that those from the Lavan Island. The present study investigated Zn, Mg, Fe and Cu in soft tissues of P.radiata, also examined the relationship between accumulation of metals and weight of the pearl oyster. Total weight, shell weight, and weight of the soft tissues were recorded. Concentrations of the metals of the soft tissues were measured using atomic absorption. There was no difference between specimens of the two Islands in Cu concentration of the soft tissues. However, there were significant differences between the specimens of the two islands in Fe, Mg and Zn. Also, there were significant differences in total weight and the weight of the soft tissues but not in shell weight. There was no relationship between metal concentration of the soft tissues and weight of shell and soft tissues in specimens from the Lavan Island but, in those from the Hendourabi Island, there was a relationship between Cu and Mg concentrations and weight of the shell and soft tissues. In conclusion, it seems that P. radiata from the Hendourabi Island are less stressed.
