Abstract

The aim of the present study is to determine the levels of  toxic heavy metal; the lead in the liver and muscle tissues of  little tuna (Euthynnus alletteratus), from the Oran coastline. Metal levels in fish samples were analyzed by using atomic absorption with flams. 120 readings were carried out betweenOctober 2012 to febury 2013. The average concentrations recorded in the fish, in this study, ranged, respectively, between 0,42 to 0,67  mg/kg for liver,  0,23 to 0,39 mg/kg for muscle and between 0,36 to 0,42 mg/kg for gonads.  The levels measured in liver tissue are higher than those reported for muscle tissue. The present study confirms that the little tuna from the Oran coastline can bioaccumulate heavy metals from a polluted environment. The average concentrations of Pb, recorded in our study, were above FAO limiting standards for food fish.
