The concentrations of polycyclic aromatic hydrocarbons (PAHs) were examined in African Giant Snail samples collected from five snail farms in Etche Local Government Area, Port Harcourt, Rivers State, Nigeria. With the view to providing information on the health risks to humans from the consumption of these foods. The concentrations of PAHs were measured by means of Gas Chromatography Mass Spectrophotometer (GC-MS). The results obtained from the analysis showed that the concentrations of 16 PAHs in the snails ranged from 0.04 to 4.148 mg/kg. The dominant PAHs compounds in the snail species were 3-, 5- and 7- rings PAHs which are phenanthrene, benzo(b)fluoranthrene and indeno(1,2,3-cd)pyrene which suggests worrisome pollution levels of the soil and environment of Port Harcourt Nigeria. The findings of this study thus point to the need for improved caution in the consumption of snails harvested from the study area. It is expected that this will help to improve public health awareness and practice.
