  • Determination of Phenanthrene in Urban Runoff of Tehran, Capital of Iran

    ABSTRACT In many big cities, surface runoff is collected by separate collection system and is then directed to receiving water bodies. Since it washes out the materials from the surface of different lands, is known as the source of pollution. Polycyclic aromatic hydrocarbons (PAHs) are one class of carcinogenic contaminants that are commonly found in storm water runoff. In this study, ...
