ClearBioaccumulation and potential sources of heavy metal contamination in fish species in River Ganga basin: Possible human health risks evaluation
Researchers assessed heavy metal contamination in seven commonly consumed fish species from the Ganga River basin in India, measuring zinc, lead, copper, cadmium, and chromium levels. They found that chromium, cadmium, and lead concentrations in river water exceeded safe limits at all sampling sites, with the highest metal accumulation occurring in fish liver tissue. The health risk assessment indicated potential long-term hazards for human populations consuming fish from these contaminated river segments.

Histopathological alterations in gills of common carp (Cyprinus carpio Linnaeus, 1758) as a biomarker of heavy metal pollution in Narmada River
This study assessed heavy metal contamination in six sites along India's Narmada River and examined associated histopathological damage to common carp gill tissue, finding site-dependent metal accumulation patterns that correlated with measurable tissue injury in fish.
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.
Logam Berat Mercury (Hg) dan Arsen (As) pada Hasil Tangkapan Nelayan Pesisir Semarang dan Tegal Jawa Tengah
This Indonesian study measured mercury and arsenic levels in fish caught by coastal fishers in Semarang and Tegal, finding heavy metal concentrations that highlight contamination risks for communities depending on local seafood.
Risk assessment of heavy metals in the freshwater lake sediments around Eppawala phosphate deposit, Sri Lanka
Not relevant to microplastics — this study assesses heavy metal (including chromium, cadmium, lead, and arsenic) contamination in freshwater lake sediments near a phosphate deposit in Sri Lanka, finding elevated concentrations likely linked to agricultural practices.
Microplastics and heavy metals in freshwater fish species in the southwestern region of Bangladesh: An emerging concern for public health
Researchers examined seventeen freshwater fish species from Bangladesh and found microplastics in all of them — mostly tiny fibers under 1mm made of polyethylene — alongside concerning levels of heavy metals including chromium and lead. While microplastic-linked health risks were low to moderate, the heavy metal contamination posed elevated cancer risks for people who regularly eat these fish.
Micro-essential and toxic heavy metals in surface water of Harike wetland - India
Researchers measured concentrations of both bio-essential (chromium, manganese, iron, cobalt, nickel, copper, zinc) and non-essential (arsenic, mercury, cadmium, lead) heavy metals in surface water of Harike wetland, the largest Ramsar-designated wetland in northern India, using inductively coupled plasma-mass spectrometry. They found alarming concentrations of iron (437.98 ug/L), mercury (4.01 ug/L), and lead (156.72 ug/L), attributing contamination to industrial, domestic, and agricultural inputs from the Sutlej River.
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.
