Abstract: Nigeria has had an abundance of oil since 1956, but the nation is still unable to meet its citizens’ fuel needs. The country’s refineries have little production capacity and are almost all moribund. As a result, there is a proliferation of unconventional refineries across the oil-producing states of the South-South region of Nigeria, despite its attendant environmental and health challenges. The purpose of this study was to compare the concentration of heavy metals across some artisanal crude oil refining sites in South-South Nigeria. The results show that Rivers state has the most polluted soil, and that the concentration of heavy metals decreases with distance from the production site. The concentration of heavy metals in mg/kg, with distance from the production sites decreased with distance from the site of production. This study concludes that, while improving the production process of artisanal refining in the study area, it is also important to remediate the already destroyed environments
