ABSTRACT

The aim of this study was to determine the levels of heavy metals in soil,
water, plants and fish samples from Matara-Uku wetlands. Twenty (20)
samples of soil, water, two plants samples (moringa Oliefera and paulliria
pinnata) and six Tilapia fishes were collected from the four sites. The
heavy metals (Pb, Ni, and Cd) levels in the digested samples were
analyzed using Atomic Absorption Spectrophotometer. The mean levels
of the heavy metals analyzed for the water samples ranged between
(0.127) to (0.273) mg/L for Pb, (0.00260) to (0.00530) mg/L for Cd, and
(0.0705) to (0.141)mg/L for Ni, respectively. The Concentration of Pb
exceeded the maximum permissible limit of 0.01mg/L for surface water.
The heavy metals levels in plant samples ranged between (3.0) to (14.7)
mg/kg for Pb, (0.056) to (3.089) mg/kg for Cd and (1.96) to (6.87) mg/kg for
Ni. The mean nickel (Ni) concentration in fish liver was 0.010633, muscle
was 0.01075 mg/kg and the average nickel (Ni) concentration in gills was
0.0111 mg/kg. The mean concentration of Pb in muscles was 0.01015
mg/kg and in gills it was 0.0043 mg/kg. While Cadmium, (Cd), was not
detected in all fish samples. The fish of this wetland is good for human
consumption. Keywords: water, soil, fish, plant, heavy metals
