Abstract
This paper was designed to analyzed level of heavy metals in some imported and local sweets and chewing gums in Bauchi metropolis. Considering the standard permissible limit of the studied metals in the samples, the result shows that these samples contained higher concentration of Ni in both sweets and chewing gums studied. Which are higher than the prescribed limit or exceeded the permissible limit which is 1mg/g for Cu according to FAO/WHO while lower limit was prescribed by the Poland national standard limit (0.3 mg/g). Cr concentration also exceeded the allowable limit of 1mg/g. So also the mean Ni concentration in both samples of sweets and chewing gum (15.78 and 9.35mg/g) were also above the nickel standard level (0.1 – 0.5mg/g) in the food stuffs, set by FAO (2001).
