title: Trace Metals in Unio tigris Mussels at Tigris River in Maysan Governorate, Southern Iraq
abstract: This study evaluated the concentrations of several heavy metals – lead (Pb), nickel (Ni), copper (Cu), zinc (Zn), cobalt (Co), cadmium (Cd), and iron (Fe) – in the tissues of the freshwater mussel Unio tigris collected from seven locations along the Tigris River in Maysan Governorate, southern Iraq. The analysis was performed using Inductively Coupled Plasma (ICP) spectroscopy. The results revealed significant variation in metal concentrations across the study area. Overall, high accumulations o
