EVALUATION OF SOIL CONTAMINATION STATUS IN APPROVED MECHANIC VILLAGES IN LAGOS STATE, NIGERIA

Authors: Odunlami M.O, *Salami L

ABSTRACT

Soil contamination is a threat to soil integrity. This work was carried out to evaluate soil contamination status in approved mechanic villages in Lagos State, Nigeria. Soil samples were collected from the surface layer (0 – 15 cm) of Ilasamaja, Animashaun, Idi-Odo, Ojota and Owutu mechanic villages in Lagos State. Samples were also taken 1 km from each of the aforementioned mechanic villages. All the soil samples were analysed for zinc, iron, lead, copper, sodium, potassium, manganese, cadmium, silver, nickel and chromium using an Atomic Absorption Spectrophotometer. The geoaccumulation index for iron, lead, sodium and manganese varied between 14.81 and 17.95, 4.15 and 9.67, 5.01 and 8.12, 5.10 and 10.89 respectively in the investigated soil. The contamination factor for lead and copper ranged between 1.03 and 58.05, 1.03 and 41.87 respectively. The results showed that the mechanic village soils investigated have a very high contamination factor as well as high pollution load index. Based on the results obtained, it is recommended that urgent and immediate actions are required to ameliorate the conditions of the investigated soils.
