Abstract This study investigated the potential health risk due to dietary exposure to Polycyclic Aromatic Hydrocarbons (PAHs) for the populace living around selected industrial areas in the south eastern states of Nigeria. The concentrations of PAHs were measured in edible food crops using Gas Chromatography - Flame Ionization Detection (GC-FID). The mean concentration of PAHs in food crops collected ranged from < 0.01 to 2.64 ± 0.02, 5.27 ± 0.04, 0.96 ± 0.02, 8.94 ± 0.01 and 1.95 ± 0.06 in mg/kg for Osisioma, Ishiagu, Irete, Akwuuru, and Ngwo respectively. PAHs distributions in food samples analyzed in this study showed vegetables to be significant higher (p ≤ 0.05) in the order vegetables > fruits > nuts > tubers. Total PAHs (ΣPAHs) concentrations in most crop samples had highest values 14.49, 36.29, 4.59, 23.36 and 21.8 mg/kg for Chyrysophyllum albidum, Telferia occidentalis, Vernonia amygdalina, Talinum triangulare and Elaies guinnensis for Osisioma, Akwuuru, Irete, Ishiagu and Ngwo respectively. The low molecular weight-PAHS/high molecular weight-PAHS were < 1 with values 0.76, 0.18, 0.28, 0.91 and 0.12 for Osisioma, Irete, Akwuuru, Ishiagu and Ngwo respectively. 58.3% and 71.7% of ΣB(a)P and ΣPAHs in food samples in the study areas exceeded the permissible limits set by DPR and EU. The estimated daily intake of PAHs via the ingestion of food crops were within the tolerable range. The carcinogenic risk values for the food crops were within the predicted permissible lifetime risks of carcinogen (10−6-10−4) for adults and children in Osisioma, Akwuuru, Ishiagu and Enugu respectively. Therefore, this study suggests that the populace around industrialized areas in South Eastern Nigeria, may be at risk due to PAHs exposure through food consumption.

Exposure to polycyclic aromatic hydrocarbons (PAHs) may lead to adverse health risks. To understand the potential sources and carcinogenic risks of PAHs in Tangshan, 40 PM2.5 samples were collected for analysis of eighteen PM2.5-bound PAHs during non-heating period and heating period. The results display a significant variation. The median concentration of ∑18PAHs during the heating period (282 ng/m3) was higher than during the non-heating period (185 ng/m3). Especially, the median concentration of Benzopyrene (BaP) during the heating period (61.6 ng/m3) was 16.9-fold that during the non-heating period (3.64 ng/m3). It exceeded BaP annual average limit of China (1 ng/m3). Diagnostic ratios (DRs) and principal component analysis (PCA) both indicated that vehicle emissions and coal and biomass combustion were the dominant contributors of PAHs pollution in Tangshan. The incremental lifetime cancer risk (ILCR) of three age groups (children, teenagers, and adults) ranged from 2.56 × 10−6 to 5.26 × 10−5 during the entire sampling periods. The 95% risk values of adults exceeded 10−4 during the heating periods, indicating a potential health risk from PAHs.
