Background: Industrial waste generally contains a lot of heavy metals such as Plumbum (Pb), Arsenic (As), Cadmium(Cd) and Mercury (Hg), which can contaminate the surrounding environment and cause health problems. Bioaccumulation ofheavy metals from the environment can occur in foodstuffs. The study aims to determine levels of heavy metals Pb, Cd, Asand Hg in foodstuffs in the oil refi nery industry. Methods: The analytical method used Atomic Absorption Spectrophotometer(AAS). Samples were taken from two locations, namely: the exposed area and non exposed area. The sample consisted ofcassava, papaya leaves, fern leaves, cassava leaves, guava, papaya and catfi sh. Results: The analysis showed levels ofmetals As in all samples at exposed locations is below the maximum limit of SNI, the location is not exposed only in catfi shlevels of As (2.042 mg/kg) exceeds the SNI. Cd levels of both locations are not detected. Pb levels in catfi sh in exposedlocations (1,109 mg/kg) exceeds the SNI. Hg levels in leaves of papaya, cassava leaves, fern leaves, cassava and fruitpapaya exceed SNI. Conclusion: There has been a heavy metal contamination in foodstuffs. Recommendation: Thelocal people are advised to be careful when consuming food stuffs from oil refi nery industrial area.
