ASSESSMENT OF CONCENTRATION LEVEL OF TRACE METALS IN LOCAL MARINE FISH SAMPLES MARKETED IN BENGHAZI CITY, LIBYAAIMAN. M. BOBAKER, INTISAR ALAKILI, WADEEAH M. AL-AREQI AND SUKIMAN. B. SARMANIAbstract Eleven fish species marketed in Benghazi City, Libya were analysed by neutron activation analysis using k0-standardisation method, for possible contamination with zinc, mercury, arsenic, selenium and chromium. Zinc and selenium were found in all fish samples within the range of 0.44 μg/g to 6.08 μg/g and 0.45 μg/g to 7.24 μg/g, respectively. Mercury and arsenic were found in 91% of the samples ranged from ND (Not Detected) to 14.53 μg/g for Hg and from ND to 3.81 μg/g for As. Chromium was found in 46% of fish samples ranging from ND to 12.13 μg/g.
