Ebrié lagoon. This part of the Ebrié lagoon as become the main
receptacle of several discharges from industrial, agricultural, port and urban
sewage. Surface sediments were collected from eighteen stations around Abidjan
city in order to assess the catchment activities on organic matter and heavy
metals inputs into the lagoon. Some important physicochemical parameters (pH,
temperature, salinity and conductivity) were also measured. Samples were analyzed
using titration method and with an Atomic Absorption Spectrophotometer (AAS)
for organic matter and heavy metals, respectively. Levels of physicochemical
parameters were found save for aquatic life according to WHO guidelines. Levels
of organic matter were ranged within 8.05±7.32 and 67.74±14.07%
with highest contents observed in samples collected in the urban area close
to Abidjan city. The analysis of sediment samples showed Pb, Cd, Ni, Mn and
Zn levels of mean values 404.75±142.08, 2.85±1.97, 45.63±2.73,
107.46±6.51 and 208.77±81.34 mg kg-1 (dry weight),
respectively. Apart from Mn and for samples collected in the rural zone close
to Bingerville, sediments were found polluted by Pb, Cd, Ni and Zn with concentrations
higher then effects ranged severe levels. Except for Mn (p>0.05), spatial
and seasonal variations were significant (p<0.0001) for Pb, Cd, Ni and Zn.
Therefore, it is urgent to promote treatment of discharges from industries,
urban sewage, port, agricultural, etc., before their input in the Ebrié
lagoon as its sediments contamination by heavy metals remains a public health
problem.]]>Tuo, A.D., M.B. Soro, A. Trokourey and Y. Bokra,20122012Al-Hashem, M. and P.F. Brain,2009Acanthodactylus scutellatus at the greater Al-Burgan oil field in Kuwait.]]>35659Asaolu, S.S., K.O.
