Organochlorines in urban soils from Central India: probabilistic health hazard and risk implications to human population.

摘要: This study presents distribution of organochlorines (OCs) including HCH, DDT and PCBs in urban soils, their environmental human health risk. Forty-eight soil samples were extracted using ultrasonication, cleaned with modified silica gel chromatography analyzed by GC-ECD. The observed concentrations ∑HCH, ∑DDT ∑PCBs soils ranged between < 0.01–2.54, 1.30–27.41 and < 0.01–62.8 µg kg−1, respectively, which lower than the recommended quality guidelines. Human risk was estimated following Lifetime average daily dose (LADD), non-cancer or hazard quotient (HQ) incremental lifetime cancer (ILCR) for humans due to individual total OCs presented. Estimated LADD acceptable intake reference dose. estimates safe limit (HQ < 1.0) range ILCR (10−6–10−4). Therefore, this concluded that present levels (HCH, PCBs) studied low, subsequently posed low population area.
