    Ecological effects of oil spill on water and sediment from two riverine communities in Warri, Nigeria
    (Interantional Journal of Biological & Chemical Sciences., 2017-02-01) OGELEKA, Doris Fovwe; TUDARARO-AHEROBO, Laurelta Esivweneta; OKIEIMEN, Felix Ebodaghe
    The ecological effects of oil spill in the environment were studied in Warri riverine areas of Ubeji and Jeddo, Delta State, where an oil spill occurred and cleanup or remediation was not carried out for over a year prior to this evaluation. The American Public Health Association (APHA) and the American Society for Testing and Materials (ASTM) methods were employed for the laboratory test for organics [polyaromatic hydrocarbon; total petroleum hydrocarbon (TPH)] and heavy metals in the water and sediment. The results indicated that there were still significant concentrations (P <0.05) of organics indicating hydrocarbon pollution. Mean concentrations recorded for TPH in Ubeji and Jeddo waters were 23.60 ± 1.18 mg/L and 29.96 ± 0.14 mg/L respectively while total PAHs was 0.009 ± 0.002 mg/L and 0.008 ± 0.001 mg/L. Mean concentrations of TPH in the sediment was 48.83 ± 1.49 ppm and 1093 ± 74 ppm respectively while total PAHs was 0.012 ± 0.002 ppm and 0.026 ± 0.004 ppm. Low concentrations were recorded for most of the heavy metals in the water and sediment. Hydrocarbon degrading bacteria (HDB) recorded mean values of 3.86E + 03 and 3.44E + 02 for Ubeji and Jeddo waters, while Hydrocarbon degrading fungi (HDF) recorded mean values of 2.86E + 03 and 2.46E + 02 respectively. The observed concentrations of hydrocarbons in the study areas should provide the impetus for regulatory surveillance of oil discharged intentionally/unintentionally into the Warri riverine waters and sediment since hydrocarbon released into the environment sorb to the sediment particles where they cause harm to organisms in the sediment and overlying waters.

    The effects of the Niger Delta oil crisis on women folks
    (Academic Journals, 2014-01) OGELEKA, Doris Fovwe; IHAYERE, Celestina; ATAINE, Theresa Ifeyinwa
    The Niger Delta area is one of the locations that is seriously affected by oil spill in Nigeria’s fifty one years of oil exploration. This study was designed to investigate the effects of the Niger Delta oil crisis on the women folks. Oil crisis could result in vast effects on humans and animals which include social, ecological, health, economical amongst others. The environment (air, water, soil) usually indicates the presence of hydrocarbon and petrogenic pollution and this affects aquatic lives and agricultural practices. These result in decrease in fishing resources, damage to marine flora and fauna, loss of biodiversity, deforestation, coastal and marine erosion and flooding. The inability of the people to fix these problems and the supposedly government insensitivity had been the cause of persistent conflicts and confrontation with government and oil companies in the area. Women suffer great hardships in times of conflict and the Niger Delta women are no exception. During the conflicts with oil companies and the Nigerian government, women are subjected to all kinds of violence - sexual such as rape; physical violence such as beatings, maiming murder, and destruction of properties. The effects of these conflicts on the social wellbeing of the women folks in this area were assessed in this study.
