Table 1: Proximate Composition of heavy metals in Municipal battery-dust leachate (MABDL) and Elewi Odo Municipal battery recycling site leachate (EOMABRL). MABDL and EOMABRL are significantly higher (^ap<0.05) than the Permissible levels of heavy metals in drinking water recommended by World Health Organization (WHO), United States Environmental Protection Agency (USEPA), Federal Environmental Protection Agency, 1991 (FEPA) and National Agency for Food and Drug Administration and Control (NAFDAC).ND= Not detected.
