Abstract
Lake sediment is a ready sink or reservoir of pollutants including heavy metals. Studies were carried out on the quality of sediments in some lakes in Ibadan to ascertain the extent of pollution. The following lakes were analyzed: Agodi, Awba, Eleyele and IITA lakes. In this regards, four sampling points were selected for each lake and the following parameters were analyzed; % Organic carbon (OC), pH, % Organic Matter (OM), Cation Exchange Capacity (CEC), mechanical properties and heavy metals. The results revealed that CEC ranged from 94.0 meq/100g in Agodi lake to 250 meq/100g in Awba lake , % OC ranged from 0.5 % in IITA to 4.6 % in Awba lake, % OM ranged from 0.9 % in IITA to 8.0 % in Awba lake. The concentration of Cd ion in the lake sediment ranged from 0.1 μg/g in Eleyele to 1.4 μg/g in Agodi lake. Similarly, Pb ion ranged from < 0.01 in IITA to 1.7 μg/g in Agodi lake.The heavy metals data obtained from the study were above the WHO standard for heavy metals in water, which could pose serious threat to human health, water quality and the environment.
