Effects of power station and abattoir on PAH input into sediments of Oji River: ecological and human health exposure risks.

This study investigated the concentration and sources of polycyclic aromatic hydrocarbons (PAHs) in the sediments of Oji River due to point sources of pollution from abattoir and power plant and determined the ecological and human health risks associated with the PAHs in the sediments. Oji River in Nigeria receives contaminants from anthropogenic activities relating to waste tires used in singeing cow meats in abattoir and preparing hides and skin for local consumption. It also receives contaminants from power distribution station where the defunct coal power plant used to be situated.
