Integrated receptor modeling and trajectory analysis for source apportionment of heavy metals in settled dust fall across western Iran

Puntos clave

• Heavy metals were sourced and apportioned effectively using receptor modeling and trajectory analysis across multiple sites.
• The study highlights significant variations in heavy metals concentration levels, especially lead and cadmium, across urban and rural areas.
• Analysis of settled dust fall during different seasons provided insight into pollution sources, revealing industrial and vehicular emissions as major contributors.
• Findings emphasize the need for continuous monitoring and assessment of heavy metal concentrations to protect public health.”
