Humans are exposed to Potentially Toxic Metals (PTMs) through many routes. Cooking foods in cookwares which are prone to material leaching can be an exposure route to PTMs. This study assessed the effect of pH on the leaching of some PTMs from used cooking pots into deionized water. Series of deionized waters were prepared from pH 3 to 7. Each wate...

Grains amongst other plant foods are known to be rich sources of phenolic compounds which are known to exhibit high antioxidant activity. In this study, eight selected grains; polished rice (Oryza sativa), ofada rice (a peculiar rice specie cultivated in Ofada, Ogun State, Southwestern Nigeria), a wheat specie-Triticum aestivum, a millet specie-Ele...

From clinical point of view, knowledge of the pollen season and loads in the atmosphere of every community is important so as to guide on incidence and management of pollinosis. The aim of this work therefore is to evaluate the weekly constituents of the atmospheric pollen and fern spores of two communities in Lagos Nigeria and the relationship, if...

Robotics and autonomous systems are reshaping the world, changing healthcare, food production and biodiversity management. While they will play a fundamental role in delivering the UN Sustainable Development Goals, associated opportunities and threats are yet to be considered systematically. We report on a horizon scan evaluating robotics and auton...

With the advent of the SARS-CoV-2 pandemic, Wastewater-Based Epidemiology (WBE) has been applied to track community infection in cities worldwide and has proven succesful as an early warning system for identification of hotspots and changingprevalence of infections (both symptomatic and asymptomatic) at a city or sub-city level. Wastewater is only...

Informal recycling of electronic waste leads to soil contamination that can impact human health. To accurately assess exposure to potentially toxic elements (PTE) in soil it is necessary to consider their bioavailability through ingestion, inhalation and dermal contact. However, bioaccessibility tests that estimate dermal absorption following adhes...

Rapid population growth and urbanisation pose risk to the environment and public health. The aim of this manuscript is to undertake a large-scale spatiotemporal chemical profiling of chemicals of emerging...
Article
Full-text available
Pesticide use is a common practice worldwide, especially in Sub-Saharan African (SSA) countries, where ongoing agriculture intensification and the need for disease vector control make it essential. The population can thus be exposed to variable amounts of pesticides through the diet. Edible insects are a highly regarded food source in SSA. However,...

Dioxin-like polychlorinated biphenyls (dl-PCBs) are ubiquitous chemicals which mediate toxicity in a way similar to polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans. In silico modeling was used to predict the absorption, distribution, metabolism, excretion, and toxicity (ADMET) properties of eight dioxin-like PCBs in soil samples...

Spatial variations and mobility of mercury (Hg) and Hg associations with other potentially toxic elements (PTEs) were studied in soil samples from Alaba, the largest e-waste recycling site in Nigeria and West Africa. Total Hg concentration was determined in surface soil samples from various locations using cold vapour atomic absorption spectrometry...
Article
Sewage management and its implications on public health remain one of the major challenges of urbanisation faced by developing countries such as Nigeria. As a member of the United Nations (UN), Nigeria is actively involved in ensuring achievement of the Sustainable Development Goals (SDGs), especially those that have direct impact on human health a...
Article

Open municipal solid waste (MSW) combustion is a major emission source of particulate air pollution, polycyclic aromatic hydrocarbons, and more exotic hazardous organic pollutants including polychlorinated biphenyls and brominated flame retardants. However, the adverse impact of MSW combustion emission on health among the general population is unkn...
Article

The discharge of produced water (PW) and drill cuttings from oil operations may elicit varied toxicity in fresh, brackish and marine organisms when exposed. The Niger Delta region which is the oil and gas province of Nigeria have incessantly been recipients of produced water. The study was aimed at investigating the toxic effects of produced water...
Article
This study proposes a new, fast and sensitive multi-residue method for simultaneous screening of different classes of pharmaceuticals in fish using an ultrasonic assisted extraction (UAE) followed by solid phase extraction (SPE) as clean-up step and by ultrahigh-performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS). The analysis...
Article
We report concentrations of brominated flame retardants (BFRs) in 23 plastic samples from 20 new and second-hand children's toys sourced from the UK that had been previously shown to be Br-positive by XRF. The results reinforce existing evidence that the recycling of BFR-treated electronic plastics has led to the unintentional BFR contamination of...
Article
Full-text available
The occurrence of 28 pharmaceuticals and personal care products (PPCPs) was investigated in 17 surface water samples (rivers, canals, and lagoons), 12 groundwater samples (wells and boreholes, which can also be consumed for drinking) and 8 drinking water samples (bottles and sachets) during dry and rainy seasons in Lagos state, Nigeria. The most pr...

Abstract: Effluents from the paint industry have been a major source of environmental pollution. There is a need to investigate the compliance of wastewater discharged from paint industries with regulatory standards. In response, this study evaluates the physicochemical parameters of both raw and treated wastewater, the wastewater treatment plants...
Article
Full-text available
Metal pollution in soils arising from mining activities has become a growing concern especially in developing countries like Nigeria. Illegal mining of solid minerals pervades the entire country leaving behind their deleterious effects on the environment. This research focused on the preliminary studies on the distribution characteristics of nine p...
Article
Diet has been established as a major source of exposure to Polycyclic aromatic hydrocarbon for humans (PAHs) especially nonsmokers. Therefore their presence in plants constitute a major health concern. This research aims at determining the concentration and profile of sixteen US-EPA priority PAHs in tropical edible vegetables (Corchorus olitorius (...

The Lagos Lagoon system is a brackish coastal lagoon—the largest in the West African coast with a large series of estuaries—located between longitude 3o23′ and 3o40′E and between latitude 6o27′ and 6o48′N. It is a shallow expanse of water (0.3–3 m deep), 50 km long and 3–13 km wide and separated from the Atlantic Ocean by a narrow strip of barrier...
