This study evaluated the occurrence and human exposure risk of mono-aromatic hydrocarbons (MAHs) such as benzene, toluene, ethylbenzene, and o,p-xylene (BTEX) in soils from petroleum product jetty from the Niger Delta, Nigeria. Samples were collected from the top (0-15 cm), sub (15-30 cm), and bottom (30-45 cm) soil depths. The MAHs components were determined using Headspace gas chromatography-mas...
