Abstract
Indiscriminate disposal of municipal solid wastes poses serious risk of pollution in the neighboring soils. Hence, this work targeted to determine the ecological and health risk assessment of some designated heavy metals; As, Cd, Cr, Cu, Pb, Zn, Ag and V in solid waste dumpsite in Igando. Five soil samples were collected from different points of the study site while the control sample was collected about 1 km away from the study site from a depth of 0-15 cm. The sample was digested using 3:1 ratio of HNO3 and HCl and was analyzed using inductively coupled plasma-optical emission spectrophotometer (ICP-OES). The mean concentration of the heavy metals recorded in the soil samples were; 20.09 ± 35.97 Cd, 38.17 ± 24.83 Cr, 42.06 ± 50.41 Cu, 57.40 ± 40.93 V, 63.24 ± 37.60 As, 161.57 ± 145.8 Pb and 1865.7 ± 24 mg/kg for Zn, respectively, silver was not detected. Pb and Zn were exceeding the tolerable limits reported by WHO while other metals were within the WHO limits. The ecological risk assessments; contamination factor, degree of contamination, geo-accumulation index, pollution load index, and the ecological risk index were calculated and was indicated to be low contamination aside for Zn whose concentration was moderate risk; the health risk assessment which includes average daily dose through ingestion, inhalation and dermal, hazard quotient, hazard index and cancer risk were also calculated and it indicated a low risk of contamination. Hence, there is a necessity for continuous checking and sanitizing of the dumpsite before using the dumpsite for water and agricultural purposes.
