Assessment of heavy metals in
Tilapia zillii
from some Nun River Estuaries in the Niger Delta region
of Nigeria
Ayobami Omozemoje Aigberua and Timi Tarawou
Niger Delta University, Nigeria
T
his study investigated the heavy metal concentration in
Tilipia zillii
from River Nun in Bayelsa state, Nigeria. The samples
were collected from the brackish environment in the Nun River Estuary.
Tilipia zillii
were collected from creek lines
traversing five communities at Obama, Tebidaba, Clough creek, Ogbainbiri and Samabiri. The samples were preserved in ice
chest and transported to the laboratory. The fish samples were prepared by oven-drying, dry-ashing and digesting using a
mixture of nitric and hydrochloric acid. The fish samples were analyzed using flame atomic absorption spectrometry. Result
of the fish ranged from 0.380-21.555 mg/kg (lead), <0.001 mg/kg (copper), 0.190-1.670 mg/kg (chromium), 0.290-22.67 mg/
kg (manganese), 2.785-30.340 mg/kg (zinc), 40.860-195.905 mg/kg (iron) and 0.205-1.145 mg/kg (nickel). Statistically, there
was significance difference (P<0.05) in the fish collected from the different locations apart from copper. The heavy metal
concentration were above the limits recommended by various agencies including Food and Agricultural Organization/World
Health Organization, Median international standard, European Union, United State Environmental Protection Agency and
Water Pollution Control Legislation. The high concentration of heavy metals above permissible level suggests the need for
caution during the consumption of
Tilipia zillii
from the Nun Estuary due to health implications associated with heavy metals.
