Overview

Geospatial assessment reveals heavy metal contamination in water, indicating urgent waste management needs.

Key Points

  • Sediment concentrations of heavy metals, including zinc at 702.62 ppm and iron at 2,954.72 ppm, exceeded regional thresholds.
  • Integrated geospatial assessment utilized ArcGIS to identify contamination hotspots in the Way Ratai River and sediment.
  • Queensland analysis revealed cadmium and copper levels below detection limits in river water, while sediment was significantly impacted.
  • Findings highlight the necessity for waste-management protocols to alleviate heavy-metal impacts on ecosystems and human health.
