Implication
Randomized trial evaluates heavy metal pollution and associated health risks in soils across land-use areas, indicating urgent intervention needs.
Key Points
- This research aims to assess heavy metal contamination levels and their health risks in different land-use areas of Rivers State, Nigeria.
- Analyzed soil samples from industrial, agricultural, and residential areas using Inductively Coupled Plasma–Mass Spectrometry (ICP-MS).
- Evaluated pollution status and sources of heavy metals using various pollution indices.
- Conducted health risk assessment focused on ingestion pathways and carcinogenic risks.
- Found arsenic concentrations as high as 366.8 mg/kg in industrial areas, exceeding safety limits.
- Identified ingestion as the main risk factor, with hazard quotients for arsenic in children reaching 9.15, surpassing acceptable levels.
- Source identification revealed industrial emissions and agricultural practices as significant contributors to soil heavy metal concentration.
