Geochemical Background and Correlation Study of Ground Water Quality in Ebocha-Obrikom of Rivers State, Nigeria
Researchers assessed groundwater quality in the Ebocha-Obrikom area of Nigeria's Niger Delta, a region heavily affected by oil industry pollution. They measured physicochemical properties and heavy metal concentrations across multiple well water samples over a year-long period. The findings revealed correlations between certain heavy metals and water quality parameters, providing baseline data for monitoring contamination in the region.
Evaluation of the Effects of Heavy Metals on Water from Illegal Crude Oil Refineries: a Case Study of Three Selected Communities in the Niger Delta Region, Nigeria
This paper is not about microplastics; it measures heavy metal contamination (and associated health risk indices) in surface water near illegal crude oil refineries in three communities of Nigeria's Niger Delta region.
Levels of heavy metals in water and Nile tilapia fish (Oreochromis niloticus) of Eleyele Lake in Ibadan, Nigeria
This is not a microplastics study; it measures heavy metals in water and Nile tilapia from a Nigerian lake, finding that lead concentrations in fish tissue exceeded WHO and FAO limits even though water concentrations appeared acceptable, raising food safety concerns for local consumers.
Hazardous effects of heavy metal pollution on Nile tilapia in the aquatic ecosystem of the Eastern Delta in Egypt
Researchers assessed heavy metal contamination in Nile tilapia from rivers in Egypt's Eastern Delta, finding that some metals had accumulated in fish tissues at levels exceeding international safety limits — raising health concerns for people who eat fish from these polluted waters.
Water pollution and its impact on human health in Nigeria Authors
This study examined the causes and health effects of water pollution in Nigeria, where millions of people are affected by contaminated water sources from industrial waste, oil spills, and agricultural runoff. Researchers found that heavy metals, pathogens, and microplastics significantly degrade water quality, leading to waterborne diseases and long-term health problems. The study emphasizes the urgent need for improved sanitation infrastructure, stronger environmental regulations, and community-based clean water initiatives.
Occurrence and Health Implications of Heavy Metals in Microplastics from Otuoke Surface Waters
Microplastics collected from surface waters in Otuoke, Nigeria were analyzed for adsorbed heavy metals, with health risk assessments indicating that consumption of contaminated aquatic organisms could pose risks to local populations from metal-laden plastic particles.
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.
