| Popis: | The study investigated the concentration of heavy metals (Cadmium (Cd), Copper (Cu) and lead (Pd)) on topsoil of Oke-Afa refuse- dump in Isolo, Lagos, Nigeria. Samples taken from twenty (20) different spots from Oke-Afa refuse-dump were analyzed. The study linked the environmental pollution as result of concentration of heavy metals to public health. Total contents of Cadmium was found to range from 4.65 to 50.50mg/kg with mean of 19.35, total contents of Copper was found to range from 65.77 to 634.29mg/kg with mean of 259.08, and total contents of Lead was found to range from 109.23 to 821.45mg/kg with mean of 291.91. Comparison of the results obtained to those recorded in literature showed that the levels of Cadmium and Copper were very high and are referred to as heavily contaminated and contaminated respectively, while the result obtained for Lead falls within the reported range, hence considered uncontaminated. The study revealed that the Oke-Afa dump-site exposes the residents around Isolo community to unacceptable levels of environmental pollutants with adverse health impacts. It is recommended that, to forestall the ugly consequence of heavy metals in the soils of the refuse-dump; there is need to define principles, establish strategies, set up of administrative procedures, and enforce compliance and penalties for non-compliance using appropriate laws and proper waste management and disposal. Furthermore, in order to guarantee health safety in the community, knowledge of the concentration of heavy metals is expedient |
