Seasonal Variation in the Accumulation of Trace Elements and Contaminants in Five Shrimp Species from Iskenderun Bay and Their Consumibility as Human Food.
Seasonal accumulation of trace elements and contaminants in the muscle tissue of five shrimp species; Speckled Shrimp, Deepwater Rose Shrimp, Red Shrimp, Grooved Shrimp and Green Tiger Shrimp, from Iskenderun Bay of Eastern Mediterranean Sea were investigated. It was observed the period of year for the accumulation of such elements is important. Results indicate that peaks are generally reached in autumn and in spring. The levels of Zn, Fe, Cu and Ni were the highest in autumn whereas the maximum Sn and Cr concentrations were obtained in spring. The levels of Cu and Zn were found to be within the permissible limits for human consumption. Contaminants were accumulated at the highest levels in autumn. Attention has to be drawn that Cd values were above permissible limits for deepwater pink shrimp caught in autumn and winter, and for green tiger shrimp caught in autumn. Besides, the accumulation of high level of Pb in the tissue of all species except grooved shrimp whose value was low in spring should also be considered as a warning signal.
