ClearLevels of Zinc (Zn), Copper (Cu), Iron (Fe), and Cadmium (Cd) in Soil, Rice Stalk, and Oryza Sativa Grain in Ishiagu Rice Field, Ebonyi State, Nigeria; Human Health Risk
Researchers measured zinc, copper, iron, and cadmium concentrations in soil and rice grain from a Nigerian agricultural field, finding all levels within international safety limits and calculating that daily metal intake from rice consumption poses no significant health risk to adults.
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.
Assessment of Heavy Metal Exposure in Soils of Ihwrekreka Communities, Delta State, Nigeria
Soil samples from crude oil-polluted communities in the Ihwrekreka area of Nigeria's Niger Delta were analyzed for heavy metal concentrations using inductively coupled plasma optical emission spectrometry. The study assessed potential health risks to residents from exposure to chromium, nickel, lead, cadmium, and other metals elevated by decades of petroleum contamination.
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.
Monitoring and modeling of heavy metal contents in vegetables collected from markets in Imo State, Nigeria
Researchers monitored heavy metal concentrations — including cadmium, lead, nickel, and zinc — in four commonly consumed vegetables from markets across Imo State, Nigeria, assessing contamination levels and associated human health risks through dietary exposure.
Metals contamination of Aquifer in Warri and Port- Harcourt (Niger – Delta Region)
This study measured heavy metal concentrations in hand-dug well water from 12 locations in Warri and Port Harcourt, Nigeria's Niger Delta region, finding contamination levels raising public health concerns. Standard physicochemical and atomic absorption spectrometry analyses identified several metals exceeding safe drinking water thresholds.
Effects of Irrigation Water Sources on Soil Fertility, Heavy Metal Accumulation in both Soil and Rice (Oryza sativa L.)
Scientists found that rice grown with sewage water contains higher levels of heavy metals like cadmium, which can be harmful if eaten regularly. While this wastewater helps crops grow better by adding nutrients to soil, the toxic metals that build up in the rice could pose health risks to people who eat it. This research shows we need better monitoring of crops grown with recycled wastewater to keep our food supply safe.
Potentially toxic metals in irrigation water, soil, and vegetables and their health risks using Monte Carlo models
Researchers measured toxic metals including arsenic, cadmium, chromium, and lead in irrigation water, soil, and vegetables in Nigeria, finding levels that exceeded safety guidelines in all cases. The toxic metals accumulated in commonly eaten vegetables like spinach and cabbage, posing cancer and non-cancer health risks to adults and children. While focused on heavy metals, this research is relevant to microplastics because microplastics in agricultural soil can absorb and transport these same toxic metals into crops.
Proximate, Phytochemical and Antibacterial Properties of Ethanol Extracts of Zeamays and Teiferia occidentalis Plant Leaves from Plastic Enriched Compost Soil in Edo State, Nigeria
This Nigerian study examined the nutritional and antimicrobial properties of plants grown in plastic-enriched compost soil, finding differences compared to control plants. The results suggest that growing crops in plastic-contaminated soil can affect plant chemistry, with potential implications for food quality and safety.
Polycyclic Aromatic Hydrocarbons in Soil and Vegetation of Niger Delta, Nigeria: Ecological Risk Assessment
Researchers assessed polycyclic aromatic hydrocarbon contamination in soils and vegetation across Nigeria's Niger Delta, finding elevated PAH levels in both matrices near oil exploration sites with ecological risk indices indicating significant environmental concern.
Environmental and Toxicological Perspectives of Soil Microplastics in Northern Nigeria
This study examined microplastic occurrence and toxicological implications in soils of Northern Nigeria, identifying agricultural plastics, industrial waste, and urban runoff as key sources. The research addressed a gap in African soil MP research and highlighted ecosystem and food safety risks in the region.
Heavy Metal Concentration and Human Health Risk Assessment of Selected Brands of Seasoning Powder Sold in Port Harcourt, Nigeria
Researchers assessed heavy metal concentrations in four brands of seasoning powder sold in Port Harcourt, Nigeria, and found levels of arsenic, lead, cadmium, and other metals that posed potential human health risks, highlighting food safety concerns in the region.
Solid Waste Disposal and Extent of Selected Heavy Metals in Fadama Area of Sokoto City, Nigeria
This study assessed solid waste disposal practices and heavy metal concentrations in the Fadama area of Sokoto city, Nigeria, finding elevated levels of multiple metals in soil samples attributable to improper waste dumping, with implications for public health in communities living near informal disposal sites.
Impact and mitigation of lead, cadmium and micro/nano plastics in fragrant rice.
Researchers reviewed the combined risks of heavy metals (lead and cadmium) and micro(nano)plastics in fragrant rice, exploring their impact on rice quality, aroma, and safety given that over 50% of the global population consumes rice daily.
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.
