Many Oil Wells, One Evil: Potentially toxic metals concentration, seasonal variation and Human Health Risk Assessment in Drinking Water Quality in Ebocha-Obrikom Oil and Gas Area of Rivers State, Nigeria

Researchers assessed heavy metal concentrations and seasonal variation in drinking water from an oil and gas extraction area in Nigeria, finding contamination levels that pose significant human health risks including potential neurological and carcinogenic effects.

Many oil wells, one evil: comprehensive assessment of toxic metals concentration, seasonal variation and human health risk in drinking water quality in areas surrounding crude oil exploration facilities in rivers state, Nigeria

Researchers assessed toxic metal concentrations in drinking water near crude oil exploration facilities in Nigeria, finding seasonal variations and levels exceeding safety thresholds that pose serious health risks to surrounding communities.

Quality water not everywhere: Exploratory Analysis of Water Quality Across Ebocha-Obrikom Oil and Gas Flaring Area in the Core Niger Delta Region of Nigeria

Researchers analyzed water quality across the Ebocha-Obrikom oil and gas flaring area in Nigeria's Niger Delta, finding that communities near extraction operations face significantly degraded drinking water quality with potential health consequences.

Assessment of occupational risks of waste scavenging in Ilorin metropolis

Researchers assessed the occupational health risks facing waste scavengers working at dumpsites in Ilorin, Nigeria. The study found that scavenging was predominantly performed by young males with very low use of personal protective equipment and no prior safety training, and the most prevalent health issues included fever, diarrhea, cough, and skin diseases.

Effect of dietary cinnamon supplementation on the growth in length, haematology, serum biochemistry, intestinal microbiota and enzymes and histomorphological changes of the intestine, liver and the kidney of Heteroclarias (Clarias gariepinus ♀ × Heterobra ♂)

Dietary cinnamon supplementation at 1-2% significantly improved growth, blood parameters, antioxidant enzyme activity, and intestinal health in juvenile catfish over a 56-day trial. The spice enhanced beneficial gut microbiota while reducing pathogenic bacteria, suggesting cinnamon as a natural feed additive for aquaculture.

Induction of oxidative stress and DNA damage in two common fish species of rivers and reservoirs in Ilorin, Northcentral, Nigeria

Researchers assessed oxidative stress and genotoxicity in two fish species from rivers and reservoirs in Ilorin, Nigeria, finding elevated antioxidant enzymes, micronuclei, nuclear abnormalities, and DNA strand breaks in fish from two rivers with low dissolved oxygen and elevated lead concentrations. The findings indicate cytogenotoxic conditions driven by hypoxia and heavy metal contamination in those water bodies.

Efficient removal of polystyrene microplastics from seawater using a chitosan-activated carbon nanocomposite: Preparation of the adsorbent and optimisation of removal methods

Scientists created a new material that can remove up to 99% of tiny plastic particles (called microplastics) from seawater by mixing two natural substances - chitosan (from shellfish) and activated carbon. This filtering material can be cleaned and reused at least five times, making it a promising tool for removing plastic pollution from our oceans. Since microplastics can enter our food chain through seafood and sea salt, better ways to clean them from seawater could help protect human health.

WASTES, WASTES, EVERYWHERE NOT A PLACE TO BREATHE: REDRESSING AND UNDRESSING ILORIN AND YENAGOA CITY

Time for Action: Assessment of Knowledge on Hazard Analysis and Critical Control Points of Food Handlers in Standard Hotels in Lagos State, Nigeria

Researchers assessed Hazard Analysis and Critical Control Points (HACCP) knowledge among food handlers in standard hotels in Lagos State, Nigeria, using a cross-sectional survey design, finding significant gaps in HACCP understanding that represent a food safety risk given the WHO-estimated 200,000 annual deaths from food poisoning in Nigeria.

Chemical entropy generation and second-order slip condition on hydrodynamic Casson nanofluid flow embedded in a porous medium: a fast convergent method

Researchers numerically investigated the combined effects of second-order velocity slip conditions, chemical reactions, and entropy generation on non-Newtonian Casson nanofluid flow through a non-Darcian porous medium, applying a fast convergent method to solve the coupled boundary layer, transport, and energy equations and optimize thermal system performance.

RESIDENTS’ PERCEPTION ON CENTRAL STORAGE OF SOLID WASTES IN ILORIN METROPOLIS, KWARA STATE. NIGERIA

This study surveyed residents of Ilorin, Nigeria, about their perceptions of central solid waste storage, finding that waste generation outpaces collection capacity and public concern is high. Better waste management infrastructure is needed to prevent plastic waste from entering the environment.

Concentrations of Pesticides Residues in Grain Sold at Selected Markets of Southwest Nigeria

This study measured pesticide residue concentrations in grains sold at markets in southwest Nigeria, finding detectable levels of several agricultural chemicals. Pesticide contamination of food crops is a persistent public health concern in regions with limited regulatory oversight.
