The concentration of PAHs in roadside oil-sludge was measured at outside of Mathura-Refinery, Delhi-Agra, National Highway No. 2, The samples were extracted with n-hexane by ultrasonic agitation and aromatic fraction analysis by GC. Total mean concentration of PAHs was found to be 11.34 µg g-1 and ranged from 4.43-22.53 µg g-1. Fluoranthene, chrysene, benzo (b) fluoranthene were found to be the most abundant PAHs at this location.
