Abstract: The concentration of 13 PAHs in groundwater was measured at 12 locations of Agra. The mean concentration of TPAH in all samples was 31.86 ng L⁻¹ and it ranges from 13.2 ng L⁻¹ to 64.3 ng L⁻¹. The 4-ring and 5-ring PAHs were found to be dominant in the groundwater of Agra region having 38.6% and 26.4% of the TPAH. The carcinogenic potency was estimated and it was found 2.7 ng L⁻¹. Univariate Pearson correlation matrix shows a good correlation among all PAHs except B(a)P. The levels of PAHs in the groundwater can help in environment risk assessment of this area.
