The study aims to evaluate heavy metal contamination and ecological risk in Nile Delta lagoons using pollution indices.
Investigated sediment samples from Lake Edku and Lake Mariut.
Used pollution indices and sediment quality guidelines to assess metal contamination.
Analyzed seasonal and spatial variability in heavy metal concentrations.
Cadmium was identified as the most toxic metal with an ecological risk index exceeding 223.
Pollution Load Index indicated all stations had PLI > 1.0, suggesting high pollution levels.
Around 50% of the sediment stations were rated as highly polluted, showing significant anthropogenic influence.
