Abstract
Exposure to benzo(a)pyrene (B(a)P) for health risk was studied in soils from the Delhi region, India. The mean and median concentrations of benzo(a)pyrene were 0.031 and 0.029 (±0.002) mg/kg, respectively. The lifetime average daily dose (LADD) for adults and children was 1.7 × 10-8 mg kg-1 d-1 and 7.5 × 10-8 mg kg-1 d-1, respectively, with incremental life time cancer risk (ILCR) of 1.2 × 10-7 and 5.5 × 10-7, respectively. The Index of Additive Cancer Risk (IACR) was 0.084. Our screening-level risk assessment shows that the observed ILCR and IACR values are much lower than the guideline values of 10-6 - 10-4 (ILCR) and <1 (IACR), respectively, and therefore the measured B(a)P levels in soil may not portend environmental and human health risks. © 2013 Copyright Taylor and Francis Group, LLC.
