Assessment of Potential Ecological and Human Health Risk of Some Selected Heavy Metals in Street Dusts in Ilam
Long- term exposure to street dust because of the potential toxicity of heavy metals can cause harmful effects on the humanchr('39')s health by inhalation, ingestion and dermal contact. In this study, 25 dust samples were collected from the sidewalks of the main streets of Ilam and analyze...

In this study, 25 dust samples were collected from the sidewalks of the main streets of Ilam and analyzed by inductively coupled spectroscopy (ICP- OES) method.
