Street foods are local fast food sold by vendors in congested locations. The presence of unwanted chemicals and their toxicological health risk posed by their consumption has engineered this study to assess the level and health risk of heavy metals (Pb, Cd, Hg, Sb, Mn, and Al) and polycyclic aromatic hydrocarbons in street foods consumed in Benin City and Umunede. Twenty commonly consumed street foods were randomly acquired from bus stops from both locations in Nigeria. Concentrations of heavy metals and PAH were measured by Atomic Absorption Spectrophotometry and Gas Chromatography respectively. The method used to assess the potential health risk of heavy metals and PAH was developed by the United States environmental protection agencies. All the food samples analyzed for heavy metals contained Pb in the range of (0.014-1.37mg/kg) and were in violation of the permissible limit set by WHO. The highest level of Pb was detected in beans (1.37mg/kg). The conc. of Cd, Hg, Sb, Mn and Al were below the permissible level set by WHO. The estimated daily intake, THQ and HI for all the heavy metals were below the tolerable daily intake (TDI) and threshold of 1 except for some food samples such as beans, white rice, moimoi and stewed meat that violated the Pb TDI, THQ and HI limit indicating a probability of a non-carcinogenic health risk. The PAH concentration, dietary intake and total dietary intake of B(a)P and PAH4, were well above the guideline limits. Pb and Cd were the primary heavy metals posing cancer risk. The total cancer risk of heavy metals and PAH were within the acceptable limit of 1/106.
