Soot is a black solid dispersed in air, which comes from the combustion of hydrocarbon molecules. From this study, some samples of Telfairia Occidentalis, local leaves (ugu) were collected from both Jeddo community (close to Warri Refinery and Petrochemical Company WRPC and other artisanal refineries) and Osubi Community (where there are no gas-flaring activities); all located in Okpe local government of Delta State, Nigeria. The vegetables were taken to the laboratory for analysis: to ascertain the level of heavy metal contamination from the soot that came from the gas-flaring and artisanal refineries in the area. From the result obtained, it was discovered that Zn, Cr, Cd and Pb in the vegetation had higher values above the WHO (1996) permissible limit, while Cu and Ni present in the vegetable, had values below the WHO permissible limit. This implies that soot from artisanal refineries had negative impact on the leafy vegetables (T. Occidentalis) in Jeddo community. These results then make the vegetation samples from Jeddo community unsafe for human consumption. The policies regulating the refineries should be enforced to achieve a safer atmosphere in the environment.
