The aim of the study was to determine the actual content of polycyclic aromatic hydrocarbons in honey sold in Kumasi. Polycyclic aromatic hydrocarbons are group of different compounds released from burning oils, trash, wood and other organic substances. Samples were collected from hawkers and retailers along the railways and market center of Kumasi Central Market. The content of polycyclic aromatic hydrocarbons in honey samples were determined using high-performance liquid chromatography with fluorescence detector. Concentration of individual polycyclic aromatic hydrocarbons ranged from 9 × 10-4 µg/kg (Pyrene) to 1956960 × 10-4 µg/kg (naphthalene). Naphthalene recorded the highest mean value (150535 × 10-4 µg/kg) which exceeded the limit set for both children and adults. The limit of Benzo (a) pyrene for infant formula (10000 × 10-4 µg/kg) was not exceeded. Compositional pattern of polycyclic aromatic hydrocarbons showed greater percentage of low molecular weight PAH. Pollution emission in honey reported polycyclic aromatic hydrocarbons contamination from burning of wood, grass and coal.
