Abstract
Alaba International Market is one of the oldest and largest e-waste recycling site in Nigeria. The e-wastes are recycled crudely with minimal regard to environmental impact. The influence of these activities on the concentrations of potentially toxic element in and around the site is of concern and requires investigation.
Soil samples from the vicinity of the Alaba e-waste recycling site in Lagos were collected during wet, intermediate and dry seasons for two years. They were dried, sieved and subjected to microwave-assisted aqua regia digestion. The digests were analysed for Cu, Cr, Fe, Mn, Pb and Zn and using an Agilent 7700x ICP-MS instrument.
The results of the pseudototal analysis showed that the concentrations of the potentially toxic elements were higher than permissible limits recommend by the Nigerian Federal Environmental Protection Agency Act (1991). Higher concentrations were generally recorded in the dry seasons. Levels were dependent upon proximity to the recycling site and activities carried out there.
