This study assessed concentrations of heavy metals (Pb, Cd, Zn, Fe, Cu, Cr, Ni) and phytochemicals in soil and rice samples from agricultural regions in Abuja and Kogi State, Nigeria, evaluating bioaccumulation risks and food safety implications for populations consuming locally grown rice.
Risk assessment of selected metallic pollutants in fish from Zuru Dam, Kebbi State, Nigeria
Researchers measured concentrations of seven metals (Fe, Zn, Cu, Cr, Co, Pb, K) in catfish and tilapia from Zuru Dam in Nigeria and performed health risk assessments, finding metal levels that may pose risks to communities consuming fish from this water body.
GIS Analysis of Organo-Contaminants and Iron Linked to Groundwater and Sediment at Boreholes in Aluu, Delta Region, Nigeria
Researchers used GIS spatial analysis to characterize organo-contaminant and iron concentrations in groundwater and borehole sediments from 10 sites at 45 m depth in Aluu, Nigeria, providing baseline data on contamination sources linked to gastrointestinal illness in communities relying on this groundwater for drinking.
Heavy Metals and their Effects on Macroinvertebrates Present in the Ojo River, Lagos, Nigeria
Researchers investigated heavy metal concentrations in the tissues of crab, prawn, and crayfish from the Ojo River in Lagos, Nigeria, assessing contamination levels in commercially harvested crustaceans and their implications for human health and aquatic ecosystem integrity.
Physicochemical Characteristics and Levels of Metal Ions in Groundwater around Abattoir and Cassava Processing Area from Odo-Oori Market in Iwo, Osun State, Nigeria
Researchers assessed the physicochemical properties and metal ion concentrations in groundwater near an abattoir and cassava processing facility in Iwo, Osun State, Nigeria, finding contamination levels that raise concerns about wastewater discharge practices and local water quality.
Bioaccumulation of Heavy Metals in Pelagic and Benthic Fishes of Ogbese River, Ondo State, South-Western Nigeria
Researchers measured heavy metal concentrations in water, sediments, and fish organs from the Ogbese River in Nigeria. The study found that while fish tissue metal levels were within permissible limits, sediment concentrations of cadmium, chromium, iron, and manganese exceeded safe thresholds, indicating moderate contamination risk that warrants ongoing monitoring.
Comparative Assessment Of Heavy Metal Accumulation In Two Commercial Fish Species (Clarias Gariepinus And Chrysichthys Nigrodigitatus) From Amansea River, Nigeria
Researchers measured heavy metal concentrations (Pb, Hg, As, Cd, Cr) in water, sediment, and tissues of two commercially important fish species from Amansea River, Nigeria. C. nigrodigitatus accumulated significantly more cadmium and chromium than C. gariepinus, with Bioaccumulation Factors indicating species-specific differences in heavy metal uptake relevant to food safety.
Suitability of Groundwater Quality for Drinking Using Water Quality Index in Kano Metropolis, Nigeria
Researchers assessed groundwater quality across 160 sites in Kano, Nigeria, using a comprehensive water quality index based on chemical, metal, and microbial parameters. They found that most groundwater sources in the region are unsuitable for drinking according to WHO and Nigerian standards, with well water generally worse than borehole water.
