Enrichment, Bioaccumulation and Health Risks of Trace Metals in Soils and Leafy Vegetables Grown on the Banks of the Ugandan Lifeline River, River Rwizi
Researchers measured six trace metals in soil and leafy vegetables grown along the banks of Uganda's River Rwizi near urban areas. The study found elevated metal concentrations linked to urbanization and industrial activities, with some vegetables accumulating metals at levels that could pose health risks to people who regularly eat produce from these riverside farms.
Risk assessment of potentially toxic elements in water, sediment, aquatic mussels, and edible crops from a gold-mining-stressed river in Northern Nigeria
Researchers assessed potentially toxic element contamination from artisanal gold mining in a Nigerian river, finding cadmium, chromium, lead, copper, and nickel concentrations exceeding WHO guidelines by roughly tenfold in water, with bioaccumulation in mussels and crops posing significant non-carcinogenic and carcinogenic health risks to local populations.
A review of the current status of the water quality in the Nile water basin
This review summarizes water quality data from the Nile River basin across 11 African countries, documenting contamination from heavy metals, organic pollutants, and emerging contaminants including microplastics. Rapid population growth, industrialization, and poor waste management are driving pollution levels up, threatening the water supply for hundreds of millions of people. The findings underscore the need for better monitoring and coordinated policies to protect this critical water resource.
Assessment of metal concentrations from recreational rivers in a tropical region (Jengka, Malaysia)
Researchers measured iron, manganese, and lead concentrations in two recreational rivers in Malaysia, finding that lead levels exceeded safe thresholds and that children face higher health risks than adults from both non-cancer and cancer effects, highlighting the need for stronger water quality monitoring near recreational waterways.
New approach into human health risk assessment associated with heavy metals in surface water and groundwater using Monte Carlo Method
Researchers used statistical modeling and Monte Carlo simulations to assess cancer and non-cancer health risks from heavy metals in water sources across Egypt's northwestern desert, finding that lead, cadmium, and chromium posed significant carcinogenic risks to both adults and children. Children faced especially high risk from skin contact with contaminated water, highlighting an urgent need for advanced water treatment in the region.
Heavy Metal Contamination in Surface Water of Harike Wetland, India: Source and Health Risk Assessment
Researchers measured levels of arsenic, cadmium, chromium, lead, and zinc in the surface water of Harike Wetland in India across different seasons. They found that cadmium and lead exceeded safe drinking water standards, particularly during winter months, with industrial discharge and agricultural runoff identified as primary sources. The health risk assessment indicated that these contaminated waters pose potential non-cancer health risks, especially for children.
Levels of heavy metals in water and Nile tilapia fish (Oreochromis niloticus) of Eleyele Lake in Ibadan, Nigeria

The study emphasizes the urgent need for improved sanitation infrastructure, stronger environmental regulations, and community-based clean water initiatives.
Co-occurrence of microplastics and heavy metals in a freshwater lake system in Indian Himalaya: Distribution and influencing factors
Researchers found widespread microplastic contamination in both the water and sediments of Manasbal Lake in the Indian Himalayas, with concentrations up to 4,020 particles per kilogram of sediment. Domestic sewage was identified as the primary source, and the microplastics were found alongside elevated levels of heavy metals like lead. This co-contamination is concerning because microplastics can absorb and transport heavy metals, potentially increasing toxic exposure for communities that depend on the lake.
