Occurrence of bisphenol A, nonylphenol, octylphenol and heavy metals in groundwater from selected communities in Ibadan, Nigeria.

Endocrine disruptors (EDs) such as bisphenol A (BPA), nonylphenol (NP), octylphenol (OP) and heavy metals in drinking water supply represent a significant threat to human health. In Nigeria, little is known about the presence of EDs in various environmental media. This study was conducted to determine the concentrations of BPA, NP and OP in groundwater samples from selected communities in Ibadan, Nigeria.

The dynamics of household water security and treatment practices: a population-based, cross-sectional study in Osun State, Southwest Nigeria.

A minimum of basic water supply service is pertinent to improving living standards and water-dependent quality of life indices. In Nigeria, 14% have access to safely managed drinking water services, though approximately 30% of water pumps and schemes are likely to fail within 12 months of construction. This study aims to determine household water security and its predictors in Osun State, Nigeria.

Menstrual hygiene management inequalities among school girls in Badagry, Nigeria.

Objectives: The study assessed menstrual hygiene management (MHM) inequalities among public and private in-school adolescents in Badagry, southwest Nigeria. Also assessed was the impact of available water, sanitation and hygiene (WASH) facilities on MHM within the school premises.

Methods: For this descriptive cross-sectional study, 420 students were selected via multi-stage sampling and data were obtained via a validated semi-structured questionnaire and observational checklist.

School water, sanitation, and hygiene inequalities: a bane of sustainable development goal six in Nigeria.

Objectives: The importance of school water, sanitation, and hygiene (WASH) in achieving the Sustainable Development Goal targets 6.1 and 6.2 in developing countries cannot be overemphasized.

Heavy metal analysis of drinking water supply, wastewater management, and human health risk assessment across secondary schools in Badagry coastal community, Lagos State, Nigeria.

This cross-sectional study was conducted to evaluate drinking water and wastewater management facilities, as well as the health risk associated with heavy metal contamination of available water sources among Badagry schools. According to Joint Monitoring Program classification, majority (60%) of the schools provided basic water service, 10% limited service, whereas 30% provided no service. Water quality parameters such as pH, Pb, Cr, Cd, and count were above the permissible limits in both public and private schools.

Spatial Distribution of Heavy Metals and Pollution of Environmental Media Around a Used Lead-acid Battery Recycling Center in Ibadan, Nigeria.

Background: Heavy metals are usually present in trace amounts in various environmental media such as water, soil, and air, and many are poisonous to human health even at very low concentrations.

Objectives: To assess the risk of heavy metal contamination of water, soil, and plants around a used lead acid battery (ULAB) recycling center in Ibadan, Nigeria.

Methods: Environmental samples (water, soil, and plants) were collected using standard methods and concentrations of arsenic (As), cadmium (Cd), antimony (Sb), chromium (Cr), copper (Cu), manganese (Mn), nickel (Ni), lead (Pb), selenium (Se), and zinc (Zn) were determined using inductively coupled plasma-optical emission spectrometry at the International Institute of Tropical Agriculture, Ibadan, Nigeria.

Association between household environmental conditions and nutritional status of women of childbearing age in Nigeria.

Maternal undernutrition remains a leading cause of morbidity and mortality in Nigeria. Yet, most interventional programmes are focused on infant and child nutrition outcomes and not on maternal nutrition-related outcomes. Evidence suggests that the integration of household environmental interventions into nutrition actions can make a difference in reducing the burden of maternal undernutrition.

Occupational and Environmental Health Risks Associated with Informal Sector Activities-Selected Case Studies from West Africa.

Most in the Economic Community of West African States region are employed in the informal sector. While the informal sector plays a significant role in the region's economy, policymakers and the scientific community have long neglected it. To better understand informal-sector work conditions, the goal here is to bring together researchers to exchange findings and catalyze dialogue.

Wealth status and sex differential of household head: implication for source of drinking water in Nigeria.

Background: Source of potable water has implication on the population health. Availability of Improved Drinking Water Sources (IDWS) is a problem in developing countries, but variation exists across segments of the population. This study therefore examined the relationship between wealth status, sex of household head and source of potable water.

Hygiene and sanitation risk factors of diarrhoeal disease among under-five children in Ibadan, Nigeria.

Background: Diarrhoea diseases are among the leading causes of morbidity and mortality in under-five-children (U-5C) in Nigeria. Inadequate safe water, sanitation, and hygiene account for the disease burden. Cases of diarrhoea still occur in high proportion in the study area despite government-oriented interventions.

Determinants of households' willingness-to-pay for private solid waste management services in Ibadan, Nigeria.

The study examined the determinants of willingness-to-pay for private solid waste disposal systems by urban households in Ibadan, Nigeria. A multistage random sampling technique was used to select 552 households for the study. Data obtained from survey were analysed using a logit model-based contingent valuation.
