Abstract :
Assessment of heavy metals concentration in
O. niloticus and C. nigrodigitatus was carried out in
Calabar, Cross River State.The people of Cross River
State depend on fish and other aquatic products for their
source of protein, thus the need to verify the safety of
some commonly consumed fish which are significant food
in Calabar. Samples were purchased from artisanal
fishermen from the landing sites of Great Kwa River at
EsukAtu and Anantigha beach and the concentrations of
heavy metals (Nickel, Copper, Chromium, Cadmium and
Lead) inliver; gill and muscle were analyzed using Atomic
Absorption Spectrophotometry (AAS). Results obtained
from the analysis of trace metals in the organs in O.
niloticusshowed the presence of the metals in different
organs of the fish at different levels of concentration.
Keywords :
Heavy metal, pollution, Oreochromis niloticus, Chrysichthys nigrodigitatus and Great Kwa River.
