Key Points

Toxic metal accumulation in sediments is significant, highlighting pollution risks in urban areas.
The levels of nickel and lead in sediments were found to be particularly elevated, with substantial implications for local ecosystems.
Assessment using sediment and biological sampling methods demonstrates the impact of urban uncontrolled landfills on the environment.
These findings may enable better environmental management strategies in urban areas, particularly around landfill sites.
