Effectiveness of wastewater treatment plant at the removal of nutrients, pathogenic bacteria, and antibiotic-resistant bacteria in wastewater from hospital source.

This study is aimed at assessing the effectiveness of hospital's wastewater treatment plant (WWTP) in removing nutrients, pathogenic bacteria, and addressing antibiotic resistance using a case study of a tertiary hospital in Ibadan, Nigeria. During the dry and wet seasons in the month of July and December, respectively, samples were collected, and analyzed using standard guidelines to examine significant physicochemical parameters of the WTTP; to evaluate the removal efficiency of biological oxygen demand (BOD) and chemical oxygen demand (COD), and to examine the prevalence of pathogenic and antibiotic-resistant bacteria. The results of this study showed that during the dry season, certain parameters exceeded acceptable limits, including temperature, total suspended solids (TSS), total dissolved solids (TDS), phosphate, and nitrate.

Indoor environmental conditions of selected shopping malls in Nigeria: A comparative study of microclimatic conditions, noise levels, and microbial burdens.

The activities of people and equipment used within shopping malls are major factors that contribute to air pollution and increased sound levels, thereby affecting indoor environmental quality and the well-being of mall operators. This study assessed indoor environmental quality through microbial characterization and measurement of environmental conditions present in selected shopping malls. Investigations were conducted at three shopping malls in Ibadan selected through convenience sampling technique.

Sanitary conditions, waste management, safety measures and sources of air pollution associated with shopping malls in Nigeria's largest city.

Objectives: Shopping malls are fast becoming one of the most visited public spaces globally. However, information on the possible environmental conditions in relation to health hazards in shopping malls is poorly documented in developing countries. This study assessed the sanitary conditions, waste management, safety measures and sources of air pollution associated with selected shopping malls in 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.

Exposure to oil pollution and maternal outcomes: The Niger Delta prospective cohort study.

Background: Maternal exposure to oil pollution is an important public health concern. However, there is a dearth of literature on the effects of maternal exposure to oil pollution on maternal outcomes in the Niger Delta region of Nigeria. This study was therefore designed to determine the effect of maternal exposure to oil pollution on maternal outcomes in the Niger Delta region of Nigeria.

Miscarriage, stillbirth, and infant death in an oil-polluted region of the Niger Delta, Nigeria: A retrospective cohort study.

Objective: To determine the association between oil pollution and miscarriage, stillbirth, and infant death in the Niger Delta region of Nigeria.

Methods: A retrospective cohort study was undertaken of pregnant women (aged 18-45 years) who attended selected health facilities in regions with high and low exposure to oil pollution from May 14, 2018, to September 27, 2018. A multistage sampling technique was used to randomly select a representative of women with high and low exposure to oil pollution.

Perception Determinants of Women and Healthcare Providers on the Effects of Oil Pollution on Maternal and Newborn Outcomes in the Niger Delta, Nigeria.

Purpose: This qualitative study examined the perception determinants of women and their local healthcare providers on exposure to oil pollution and its adverse effects on maternal and newborn outcomes in selected communities with history of oil spillage and gas flaring in the Niger Delta region of Nigeria.

Participants And Methods: Thirty-nine participants were used in this study, which included community women leaders (n=2), women of reproductive ages (n=32) and healthcare providers (n= 3 female nurses and 2 male doctors) in the selected communities in the Niger Delta region of Nigeria. The participants were chosen through purposive sampling.

Lung Function of Grain Millers Exposed to Grain Dust and Diesel Exhaust in Two Food Markets in Ibadan Metropolis, Nigeria.

Background: Despite growing concern over occupational exposure to particulate matter (PM) such as grain dust and diesel exhaust, information about the exposure level and health implications among workers in small-scale milling enterprises in developing countries like Nigeria has not been adequately documented. The purpose of this study was to assess the level of exposure to grain dust and diesel exhaust and effect on lung function among grain millers in food markets in Ibadan metropolis, Nigeria.

Methods: The study adopted descriptive cross-sectional design with a comparative approach.

Ambient air pollution exposure and lung function assessment of filling station attendants in Ibadan, Nigeria.

Background There is an increasing range of adverse health effects associated with air pollution at very low concentrations. Few studies have assessed respiratory parameters among filling station attendants. Objectives This study assessed air pollutants; particulate matter (PM10) and total volatile organic compounds (TVOC) concentrations at filling stations as well as determined forced expiratory volume in one second (FEV1) and peak expiratory flow rate (PEFR) levels among filling station attendants.

Carboxyhaemoglobin Levels among Traders Exposed to Vehicular Emissions in Three Motor Parks in Ibadan, Nigeria.

Carbon monoxide (CO) remains a leading cause of work-related chemical poisoning. Vehicular emissions are the primary daily ambient source of CO in urban Nigerian motor parks, where there have been few human exposure studies. Using a cross-sectional comparative design, we assessed carboxyhaemoglobin levels (% COHb), a biomarker of CO exposure, among traders at three motor parks (AMP, IMP, and NMP) and other traders (nonmotor park workers) in Ibadan, Nigeria, using a noninvasive pulse CO-dosimeter (Rad 57).

A comprehensive review of biomass resources and biofuel production in Nigeria: potential and prospects.

The quest for biofuels in Nigeria, no doubt, represents a legitimate ambition. This is so because the focus on biofuel production has assumed a global dimension, and the benefits that may accrue from such effort may turn out to be enormous if the preconditions are adequately satisfied. As a member of the global community, it has become exigent for Nigeria to explore other potential means of bettering her already impoverished economy.

Exposure to electric power generator noise among small scale business operators in selected communities in Ibadan, Nigeria.

Inadequate and erratic power supplies mean small businesses use electric generators for alternative power. The authors' goal in the study described here was to assess noise from electric generators and impacts in the commercial areas of Agbowo and Ajibode in Ibadan, Nigeria. Noise levels (A-weighted decibels [dBA]) were measured over 12 weeks, three times a day, during the 2010 dry season using a sound level meter.

Promoting environmental public health in rapidly urbanizing areas of less-developed countries in Africa: a collaborative interdisciplinary training in Ibadan, Nigeria.

Globally, urbanization has been occurring more rapidly in small-to-medium-sized cities in less-developed countries of Africa and Asia. Studies have suggested associations between traffic and industry-related air pollutants and adverse health outcomes. These chemical and physical exposure agents have also received increased attention for environmental quality concerns like global climate change.
