Assessment of water quality of rivers that serve as water sources for drinking and domestic functions in rural and pre-urban communities in Edo North, Nigeria.

Surface waters are important to humans because they are a significant water supply source. They are, however, under serious environmental stress and are being threatened as a consequence of developmental activities. The present study describes the physicochemical properties and water quality indices of five different rivers used for drinking and other domestic activities in rural and pre-urban communities in Edo North, Nigeria.

Biotreatment of effluent from 'Adire' textile factories in Ibadan, Nigeria.

In this present study, bacteria were isolated from wastewater and polluted soil collected from two cottage textile factories in Ibadan. These bacteria isolates were used for the biotreatment of textile mill effluent. The physicochemical parameters of the textile mill effluent before treatment were carried out and percentage decolourisation of the effluent was analysed using ultraviolet-visible spectroscopy (UV-vis technique).

Index analysis and human health risk model application for evaluating ambient air-heavy metal contamination in Chemical Valley Sarnia.

The impacts of air emissions as a consequence of industrial activities around communities of human habitation have been extensively reported. This study is the first to assess potential adverse human health effects in the Chemical Valley Sarnia (CVS) area, around the St. Clair River, using health risk models, ecological and pollution indices.

Chemometric analysis of ecological toxicants in petrochemical and industrial environments.

The application of chemometrics in the assessment of toxicants, such as heavy metals (HMs) and polycyclic aromatic hydrocarbons (PAHs) potentially derived from petrochemical activities in the microenvironment, is vital in providing safeguards for human health of children and adults residing around petrochemical industrial regions. Several multivariate statistical methods are used in geosciences and environmental protection studies to classify, identify and group prevalent pollutants with regard to exhibited trends. Chemometrics can be applied for toxicant source identification, estimation of contaminants contributions to the toxicity of sites of interest, the assessment of the integral risk index of an area and provision of mitigating measures that limit or eliminate the contaminants identified.

Management of conflicts arising from disclosure of HIV status among married women in southwest Nigeria.

This study examined if disclosure to their spouses by married women living with HIV/AIDS resulted in conflicts. Fifty-seven women completed a questionnaire on conflict indicators. While 93% disclosed their status within 6 months of diagnosis, 12.

Exploring the cultural context of HIV stigma on antiretroviral therapy adherence among people living with HIV/AIDS in southwest Nigeria.

This study explored the cultural context of HIV stigma on antiretroviral therapy adherence among people living with HIV/AIDS (PLWHA) in southwest Nigeria. Using purposive sampling, participants were recruited through a community-based organization. Consenting PLWHA participated in in-depth interviews and focus group discussions that were audio-taped.
