Assessment of Polychlorinated Biphenyls in Some Imported Honey Sold in Warri, Delta State, Nigeria

Even though honey has many health advantages, the presence of pollutants like polychlorinated biphenyls (PCBs) in it could be harmful to consumers’ health. Thus, this study assessed polychlorinated biphenyls in imported honey sold in Warri, Delta State, Nigeria to establish the safety of the honey. Ten imported honey samples were purchased from superstores in Warri, Delta State. Honey samples were analyzed for PCBs using a gas chromatograph combined with a mass selective detector (GC-MSD). All the honey samples analyzed tested positive for PCBs.

Occurrence and Source Apportionment of Polycyclic Aromatic Hydrocarbons (PAHs) in Urban Soil of Udu, Near Warri, Delta State

The occurrence and sources of polycyclic aromatic hydrocarbons (PAHs) were assessed in urban soils of Udu, near Warri in Delta State, Nigeria. The PAHs were quantified with gas chromatography equipped with flame ionization detector (GC-FID) after extraction and clean-up of the extracts with n-hexane/dichloromethane. The concentrations of ∑16 PAHs in the urban soils ranged from 269 µg kg-1 to 853 µg kg-1 .
