Abstract: 
This research work was carried out to investigate heavy metals in soil samples affected by burnt hospital waste standards analytical procedure. The result reveals the presence of the following heavy metals concentration ranges from chromium (Cr) 0.90 ± 0.12-1.20±0.00 (mg/kg), lead (Pb) 1.10±0.0-2.20±0.11 (mg/kg), Silicon (Si) 0.05±0.03-2.20±0.11 (mg/kg), Cadmium (Cd) 0.55±0.13-0.55±0.02 (mg/kg), silver (Ag) 0.03±0.01-0.05±0.03 (mg/kg), Cobalt (Co) 0.06±0.14-0.88±inc (Zn) 10.00±0.01-11.12±0.11 (mg/kg). However, higher concentrations were recorded for zinc, lead and chromium. Hence the need for proper method of disposing hospital waste is recommended and the health care waste managers should be educated on the implication of improper management of incinerator bottom ash and regulates monitor hospital waste generator sites.
