Risk assessment and source identification of toxic metals in some commonly consumed fishes from a subtropical wetland system: Implications and monitoring.

Heavy metal pollution in wetland ecosystems poses serious threats to aquatic biodiversity and human health, particularly in agricultural regions with limited environmental monitoring. This study assesses the distribution, sources, and health risks of eight trace metals: lead (Pb), cadmium (Cd), chromium (Cr), manganese...

Heavy Metal Contamination (Cu and Pb) in Rhizophora apiculata Ecosystems: A Comparative Study between Two Coastal Areas in North Sumatra

Mangrove ecosystems are increasingly threatened by heavy metal contamination resulting from rapid industrial and urban development. This study evaluated and compared the concentrations of Copper (Cu) and Lead (Pb) in water, sediment, and different tissues of Rhizophora apiculata collected from Sicanang Island, Bela...

Assessment of Heavy Metals in a Rural River Receiving Agricultural Effluents: Ecological Health Implications

Heavy metal contamination of freshwater ecosystems poses significant risks to aquatic organisms, human health and the sustainability of freshwater resources. This study assessed the concentrations, spatial variation, pollution status and potential ecological risks associated with selected heavy metals in the lower sect...

One health risk assessment of heavy-metal contamination in Nile tilapia (Oreochromis niloticus) from contrasting aquaculture systems in Egypt

In water-scarce Egypt, aquaculture relies on agricultural drainage water, raising health concerns. Water and Nile tilapia were sampled seasonally from four sites (drainage versus Nile freshwater). Lead (Pb), cadmium (Cd), chromium (Cr), and mercury (Hg) were measured in water and fish tissues by ICP-MS and FAAS. Bioacc...

Toxic Metal Exposure from Ecuadorian Seafood: Dietary Exposure and Risk Characterization Across Key Commercial Species

Seafood is an important component of the Ecuadorian diet, particularly in coastal regions; however, contamination from anthropogenic activities has raised concerns about human exposure to toxic metals. This study quantified cadmium (Cd), cobalt (Co), lead (Pb), and total mercury (THg) in shrimp (Protrachypene precipua)...

Potentially toxic elements (PTEs) in marine fish caught from the mediterranean sea at Damietta city, Egypt: perspective on cooking effects and health hazard assessment

This study evaluated the concentrations of mercury (Hg), arsenic (As), lead (Pb), and cadmium (Cd) in 270 fish muscle samples comprising 90 each of flathead grey mullet (Mugil cephalus), gilthead bream (Sparus aurata), and brushtooth lizardfish (Saurida undosquamis) collected from the Mediterranean Sea at Damietta, Egy...
