Abstract

The study investigated the concentration level of Cd, Cu, Pb and Zn in e-waste polluted soil in Abraka. The concentration of all the metals in studied site were high, but not above WHO/FAO permissible limit, except Cd. The polluted site were slightly higher than the controlled site, except for Pb and Zn that show significant difference based on the statistical analysis (t = 0.01, p = 67.71, t = 0.08, p = 94.89) for polluted soil. The summarized mean values of each metals for the polluted soil, also shows significant difference from the controlled soil (61.07, 80.76, 94.21, 103.34 mg/kg and 35.67, 55.39, 75.19, 91.40 mg/kg) for Cd, Cu, Pb and Zn, respectively. The result from the study, show that e-waste dumping has impacted heavy metal contaminant into the soil, despites its age in the soil. Therefore, more research will be done to check the concentration of these metals as the e-waste is ageing and the presence of other heavy metals from the soils.
