Potentially toxic element contamination in water and sediments of the Ergene river basin (Türkiye): ecological and human health risk assessment

Source Apportionment and Concentration of Potentially Toxic Elements in Surface Water and Sediments of Okulu-Aleto River, Rivers State, Nigeria

Urbanization and industrial activities continuously introduce potentially toxic elements (PTEs) into the terrestrial and aquatic environments, leading to various health-related challenges. This study evaluates the concentration of PTEs (Cadmium (Cd), Chromium (Cr), Copper (Cu), Nickel (Ni), Zinc (Zn), Lead (Pb) and Iro...

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...

Assessing Health and Safety Risk of Heavy Metals in Microplastics in Surface Water of Otuoke, Niger Delta, Nigeria

Microplastics serve as vectors for heavy metals in aquatic environments, posing potential ecological and human health risks. This study assessed the concentrations of cadmium (Cd), copper (Cu), chromium (Cr), iron (Fe), manganese (Mn), nickel (Ni), lead (Pb), and mercury (Hg) adsorbed onto microplastics in surface wate...

Geochemical Assessment of Heavy Metal Contamination in North Riyadh Soils: Pollution Indices and Multivariate Source Apportionment

This study provides baseline information for environmental assessment in North Riyadh, Saudi Arabia. It assessed the concentrations of eight heavy metals, namely cobalt (Co), chromium (Cr), copper (Cu), iron (Fe), nickel (Ni), lead (Pb), vanadium (V), and zinc (Zn), in 28 surface soil samples collected across the area....

Pollution and Ecological Risk Assessment of the Bioactive Trace Metals in the Sediment of Cross River Estinary, South South Nigeria

The bioactive elements (Fe, Zn, Mn, Mg, Ni, Cd, Cr and Pb) of the surface sediments of five stations (CE 1,2,3,4,5) along the Cross River Estuary Calabar was investigated. Their levels of contamination/pollution and ecological risk on the sediments were assessed using acceptable indices. This was carried out for both d...
