Polycyclic Aromatic Hydrocarbons (PAHs) are released into the environment from anthropogenic sources, such as combustion of fossil fuels, refused burning, industrial processes and motor vehicle exhausts. The concentration of PAHs in roadside soil was measured at St. John's crossing, which lies in the centre of Agra city and exposed to heavy traffic.
