    Effectiveness and Risk Assessment of Bio Sand Filters (BSF) technique in Rural Water Purification
    (Chemistry Research Journal, 2020) Doris Fovwe Ogeleka; Mildred Chukwuedum Emegha
    Every human deserves the right to consume safe water as it is the basic necessity for their existence and sustenance. The study was aimed with the view of ascertaining the effectiveness of carbon and gravel-based bios and filters in treating rural waters and evaluating the risk of consumption using the water consumption risk assessment matrix (W-CRAM). The treatment using the carbon-based biosand filter (BSF) at Falcorp Mangrove Park increased the pH from 5.46 ± 0.05 to 7.5±0.3while gravel-based biosand filter at Otsoron community increased minimally from 4.43 ± 0.2 to 5.86 ± 0.4. For all the locations, there was 100% eradication of E. coli. Using the W-CRAM, the untreated waters had a 62% - 69% conformance and was rated medium risk and since it will affect people (P), the risk level could be classified as 3 E or 15 (P). However, after treatment, there was an increase between 77% and 100% conformance, with above 80% classified as excellent water quality with low risk rated as 1E or 5 (P). The study concluded that no water should be consumed if the non-conformance was contributed by microbial entities as severe health risk may set in.

    The effects of the Niger Delta oil crisis on women folks
    (Journal of African Studies and Development, 2014-01-29) Celestina Ihayere; Doris Fovwe Ogeleka; Theresa Ifeyinwa Ataine
    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.
