Abstract:The concentrations of selected potentially toxic metals and other soil physico-chemical variables in soil receptacles of a solid waste dumpsite at Onne, Nigeria were assessed to ascertain the levels of contamination and ecological risks. Surface soils (0 – 20 cm depth) from four sampling areas (north, south, east and west) of the dumpsite were analyzed for Cd, Pb, Ni, As and Cr, using atomic absorption spectroscopy. Single and integrated ecological risks indices were calculated using established models. Result… Show more
