Heavy metals pollution at municipal solid waste dumpsites in Kano and Kaduna states in Nigeria
Abstract
solution and atomic absorption spectroscopy. The ranges of Cd, Cr, Ni and Pb levels for all the dumpsites were 0.30–49.8, 5.76–139, 0.39–19.1 and 42.6–9662 mg/kg, respectively. Kano dumpsite 2 was found to pollute most
with Cd, Cr and Pb in 50-100 % soil samples collected having concentrations higher than the threshold limits set by regulatory body. Paper and food scraps showed higher percentages in both Kano and Kaduna dumpsites. The
soil was high is sand for all the dumpsites implying high leaching potentials of the heavy metals pollutants.
