The health risk of polychlorinated biphenyls (PCBs) exposure from Ugbuwangue, Ugbori and Edjeba rivers sediments in Warri-South, Warri, Delta State was investigated. Nine sediment samples were collected; three samples each along the course of the different rivers. The sediment samples were Soxhlet extracted with acetone/dichloromethane/<italic>n</italic>hexane (1:1:1 v/v). A total of 28 PCBs were quantified using gas chromatography coupled with mass spectrometry detector. The concentration of the 28 PCBs ranges from 178.76-1398.29 ng g−1 for Ugbuwangue river, 224.81-685.19 ng g-1 for Ugbori river and 539.33-7858.3 ng g−1 for Edjeba river. The concentration of 12 PCBs were recorded for dioxin-like PCBs ranged from 0.08-401.52 ng g−1 (Ugbuwangue river 0.13 to 223.11 ng g−1, Ugbori river 0.08 to 153.39 ng g−1 and Edjeba river 0.32 to 401.52 ng g−1), while the concentration of 16 non-dioxin-like PCBs were recorded ranging from 0.13-4245.71 ng g−1 (Ugbuwangue river 0.18 to 386.47 ng g−1, Ugbori river 0.13 to 111.98 ng g−1 and Edjeba river 0.31 to 4245.71 ng g−1). The ecological risks of the nine sediment samples were investigated and it ranges from 25.52 – 1122.616 with Edjeba river sediment having the highest ecological risk while Ugbuwangue river sediment has the least ecological risk.

The health risk of polychlorinated biphenyls (PCBs) exposure from Ugbuwangue, Ugbori and Edjeba rivers sediments in Warri-South, Warri, Delta State was investigated. Nine sediment samples were collected; three samples each along the course of the different rivers. The sediment samples were Soxhlet extracted with acetone/dichloromethane/nhexane (1:1:1 v/v). A total of 28 PCBs were quantified using gas chromatography coupled with mass spectrometry detector. The concentration of the 28 PCBs ranges from 178.76-1398.29 ng g−1 for Ugbuwangue river, 224.81-685.19 ng g-1 for Ugbori river and 539.33-7858.3 ng g−1 for Edjeba river.
