Abstract In this study, the ambient persistent organic pollutants (POPs) such as polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and organochlorine pesticides (OCPs) concentrations were measured for 12 months at urban and semi-urban areas using the passive air sampler. During the sampling period, a total of 14 PAH (∑14PAH) concentrations measured in urban and semi-urban areas were found as 54.4 ± 22.6 ng/m3 and 51.7 ± 34.3 ng/m3, respectively. Molecular diagnostic ratios (MDRs) were used to determine PAH sources. According to the MDR values, combustion sources are the most important PAH sources in both sampling areas. However, since the urban area is close to the industrial zone, the combustion sources occurred at high temperatures (> 800 oC), while the semi-urban area generally consisted of burning petrogenic fuels. ∑50PCB concentrations measured in the urban and semi-urban areas were found as 522.5 ± 196.9 pg/m3 and 439.5 ± 166.6 pg/m3, respectively. Homologous group distributions were used to determine the source of PCBs. According to homologous group distributions, Tri-, Tetra-, and Penta- chlorinated PCBs were dominant in both sampling areas. ∑10OCP concentrations measured in urban and semi-urban areas were found as 242.5 ± 104.6 pg/m3 and 275.9 ± 130.9 pg/m3, respectively. Also, α-HCH/γ-HCH and β-/(α + γ)-HCH ratios were used to determine the source of OCPs. Lindane was the predominated OCP in both sampling areas.

On the use of PAH molecular diagnostic ratios in sewage sludge for the understanding of the PAH sources. Is this use appropriate?

Polycyclic aromatic hydrocarbons (PAHs), 33 methylated PAHs (Me-PAHs), and 14 nitrated PAHs (NPAHs) were measured in wastewater treatment plants (WWTPs) to study the removal efficiency of these compounds through the WWTPs, as well as their source appointment and potential risk in the effluent. The concentrations of ∑PAHs, ∑Me-PAHs, and ∑NPAHs were 2.01–8.91, 23.0–102, and 6.21–171 µg/L in the influent, and 0.17–1.37, 0.06–0.41 and 0.01–2.41 µg/L in the effluent, respectively. Simple Treat 4.0 and meta-regression methods were applied to calculate the removal efficiencies (REs) for the 63 PAHs and their derivatives in 10 WWTPs and the results were compared with the monitoring data. Overall, the ranges of REs were 55.3–95.4% predicated by the Simple Treat and 47.5–97.7% by the meta-regression. The results by diagnostic ratios and principal component analysis PCA showed that “mixed source” biomass, coal composition, and petroleum could be recognized to either petrogenic or pyrogenic sources. The risk assessment of the effluent was also evaluated, indicating that seven carcinogenic PAHs, Benzo[a]pyrene, Dibenz[a,h]anthracene, and Benzo(a)anthracene were major contributors to the toxics equivalency concentrations (TEQs) in the effluent of WWTPs, to which attention should be paid.

Calculated diagnostic ratios for PAHs were different from the literature

The present study was conducted to assess the carcinogenic and non-carcinogenic health risks of PAHs contamination in roasted plantain collected from three different locations within Osogbo metropolis, Nigeria. The PAHs were extracted using Soxhlet extraction technique with n-hexane and dichloromethane (3:1) as the extracting solvent. A column, packed with silica gel, was used for clean-up process and the levels of the targeted PAHs were determined by a gas chromatograph–flame ionization detector (GC-FID). The result revealed that the concentrations of total PAHs detected in the roasted samples at location A, B, C were 3.958 μg/kg, 3.654 μg/kg and 3.217 μg/kg. The HMW carcinogenic PAHs constitute about 32% of the total PAHs in the roasted plantain samples where benzo(a)pyrene, which is a marker for carcinogenicity, was found to be 9%. Comparing these results with the regulatory limits, all the analyzed roasted plantain samples were found below the maximum residual limit (MRL) of 5 μg/kg, but the calculated carcinogenic risk (CR) presented value greater than 1×10-4, signifying health risk associated with the consumption of the roasted plantain. The major source of the PAHs using diagnostic ratios (Fla/Pyr and Ph/Ant) showed that the charcoal used in roasting is a major contributing factor to the high levels of PAHs detected in the roasted plantain samples.
