ABSTRACT: Concentration of Cadmium, Copper, Lead, Zinc and Mercury were determined
in the muscles, gills and liver of ten fish species (Epinephelus areolatus, Epinephelus radiates, Anthias
squamipinnis, Plectorhinchus chaetodonoides, Snubnose emperor, Dicentrarchus labrax, Acanthopagrus bifasciatus, lutjanus
kasmira, lutjanus ehrenbergii and Acanthurus gahhm) as well
as three specimens of crustaceans (Metapenaeus dalli, Panulirus penicillatus and Portunus petagicus) and
two Specimens of squids (Parateuthis tunicate and Chtenopteryx sicula) collected
from Jeddah coastal water during 2014. The obtained results declared that, the average
concentrations of heavy metals were as follows: Cd (0.098, 0.20, 0.106), Cu
(0.358, 0.327, 1.536), Pb (0.3, 0.257, 0.196), Zn (3.00, 7.390, 4.999) μg/g wet
weight in the muscle, gills and liver, respectively. While, the concentration
of Hg was invariably undetectable in all samples of different organs of the
collected fish species. The average concentration of Cd, Cu, Pb, Zn and Hg in
the soft part of the investigated crustaceans (Metapenaeus dalli, Panulirus penicillatus and Portunus
petagicus) and squids (Parateuthis tunicate and Chtenopteryx
sicula) were relatively higher compared with the muscle tissues in the
examined fish species. The results of bioconcentration factor (BCFs) indicated
that among examined metals Zn was the most readily absorbed by fish and the
highest BAFs for examined fish species were determined in gill of Snubnose
emperor.
