Abstract:

Polycyclic aromatic hydrocarbons are considered to be potentially genotoxic and carcinogenic to humans. For non-smoking populations, food is the main source of polycyclic aromatic hydrocarbons exposure. Due to their lipophilic nature, oils and fats rank among the food items with the highest polycyclic aromatic hydrocarbon content. Consequently, the detection of polycyclic aromatic hydrocarbons in edible oils is critical for the promotion of human health. This paper reviews sample pretreatment methods, such as liquid-phase-based extraction methods, adsorbent-based extraction methods, and the QuEChERS (quick, easy, cheap, effective, rugged, and safe) method, combined with detection techniques like mass spectrometry and chromatography-based techniques for accurate quantification of polycyclic aromatic hydrocarbons in edible oils since 2010. An overview on the advances of the methods discussed herein, along with a commentary addition of current challenges and prospects, will guide researchers to focus on developing more effective detection methods and control measures to reduce the potential risks and hazards posed by polycyclic aromatic hydrocarbons.

Abstract:

The purpose of this study was to identify pollution sources by characterizing polycyclic aromatic hydrocarbons from total suspended particles in Ulaanbaatar City. Fifteen polycyclic aromatic hydrocarbons were measured in total suspended particle samples collected from different sites, such as the urban center, industrial district and ger (Mongolian traditional house) areas, and residential areas both in heating (January, March), and non-heating (September) periods in 2017. Polycyclic aromatic hydrocarbon concentration ranged between 131 and 773 ng·m−3 in winter, 22.2 and 530.6 ng·m−3 in spring, and between 1.4 and 54.6 ng·m−3 in autumn. Concentrations of specific polycyclic aromatic hydrocarbons such as phenanthrene were higher in the ger area in winter and spring seasons, and the pyrene concentration was dominant in late summer in the residential area. Polycyclic aromatic hydrocarbons concentrations in the ger area were particularly higher than the other sites, especially in winter. Polycyclic aromatic hydrocarbon ratios indicated that vehicle emissions were likely the main source at the city center in the winter time. Mixed contributions from biomass, coal, and petroleum combustion were responsible for the particulate polycyclic aromatic hydrocarbon pollution at other sampling sites during the whole observation period. The lifetime inhalation cancer risk values in the ger area due to winter pollution were estimated to be 1.2 × 10−5 and 2.1 × 10−5 for child and adult exposures, respectively, which significantly exceed Environmental Protection Agency guidelines.

Abstract:

Background Cigarette smoking is a risk factor of osteoporosis and bone fracture. Tobacco smoke contains several polycyclic aromatic hydrocarbons. Thus, we hypothesized that environmental polycyclic aromatic hydrocarbon exposure is associated with bone loss and fracture risk. The present study examined the association between polycyclic aromatic hydrocarbon exposure and bone turnover in the general adult population. Methods A total of 1408 eligible participants from the National Health and Nutrition Examination Survey (NHANES 2001–2006) were included in this cross-sectional analysis. The levels of urinary N-telopeptide and serum bone-specific alkaline phosphatase, which are biomarkers of bone resorption and formation, respectively, were assessed. Meanwhile, polycyclic aromatic hydrocarbon exposure was evaluated using the concentrations of urinary polycyclic aromatic hydrocarbon metabolites. The association between polycyclic aromatic hydrocarbon exposures and N-telopeptide, and bone-specific alkaline phosphatase levels was assessed using a multivariate linear regression model. Results All polycyclic aromatic hydrocarbon metabolites except 3-phenanthrene were significantly associated with increased N-telopeptide levels (P < 0.05) after adjustment of relevant covariables. However, no significant relationship was observed between polycyclic aromatic hydrocarbon metabolites and bone-specific alkaline phosphatase levels. This relationship remained significant after the participants were assessed according to sex (P < 0.05). Additionally, all polycyclic aromatic hydrocarbon metabolites showed a positive association with N-telopeptide levels in participants aged <60 years (P < 0.05). Conclusion Polycyclic aromatic hydrocarbon exposure is associated with increased bone resorption among the general adult population in the United States. Further studies must assess the potential mechanisms associated with the adverse effects of polycyclic aromatic hydrocarbon exposure on bone loss.

Abstract:

The release characteristics of polycyclic aromatic hydrocarbons during the pyrolysis of biomass remain poorly understood. This study investigated the effects of pyrolysis temperature on the polycyclic aromatic hydrocarbon release characteristics by analyzing both the transient vapor products and the physicochemical properties of corresponding biochar from the pyrolysis of corn stover pellets. The results revealed that the transient volatile compounds mainly included phenols, ketones, acids, furans, aldehydes, substances containing benzene ring, polycyclic aromatic compounds, and gaseous products. A range of 2 to 4 ring polycyclic aromatic hydrocarbons were generated at 400 to 700 °C with the peak at 560 °C, and the sum of relative content of polycyclic aromatic hydrocarbons ranged from 0.23% to 40.36%. For the biochar, the carbonization stage (400 to 700 °C) of corn stover pellets was further divided into three evolutionary stages, including the preliminary carbonization stage (380 to 480 °C), amorphous carbon structure stage (480 to 600 °C), and the stage of dehydrogenation and growth of aromatic rings (600 to 700 °C).The relationship between polycyclic aromatic hydrocarbon release in volatile compounds and H/C ratio of the biochar could be described by a power function.

Abstract:

For many years, PAHs have been the subject of intense controversy throughout the world, due to their high toxicity and their presence in almost all environmental media. Their hazardous nature has given rise to a number of legal requirements throughout the world aimed at effectively reducing their content in foodstuffs and certain everyday consumer products. However, technologies for remediating PAH-contaminated soils use chemical and mechanical approaches that are extremely costly and not very environmentally friendly. That's why research is currently focusing on biological approaches that can provide effective, low-cost treatment for PAH-contaminated soils, and avoid environmental repercussions as far as possible. The aim of this paper is to shed light on a biological approach to the treatment of PAHs that is still in its infancy, but which is already showing great promise: biodegradation by fungi, which differ from other organisms in that they secrete enzymes that give them the ability to feed in environments inaccessible to other kingdoms, and to absorb toxic PAH chemicals from the soil and transform them into less harmful compounds.

Abstract:

In this study, a dinitrodiphenyldiquinoline derivative is synthesized, purified, and characterized, and its adsorptive ability is examined for the first time. Twelve common polycyclic aromatic hydrocarbons are chosen as potential adsorbates for removal by using dinitrodiphenyldiquinoline as an adsorbent surface. The adsorptive capacity and the efficiency of removal depend on several variables such as adsorbent dose, polycyclic aromatic hydrocarbon initial concentration, pH, and contact time. This paper summarizes the adsorbent parameters and the kinetic models that can optimize and describe the adsorption process used to treat aqueous solutions of polycyclic aromatic hydrocarbons. Experimentally, the optimum adsorbent dose, the initial concentration, and contact time are found to be 0.1 g, 1 ppm, and 60 min, respectively. Mathematical treatment of the adsorption data reveals that the adsorption of all the polycyclic aromatic hydrocarbons by dinitrodiphenyldiquinoline adopted a pseudo second-order adsorption model. As a result, the dinitrodiphenyldiquinoline derivative is found to be a very good adsorbent surface for several hazardous organic pollutants such as polycyclic aromatic hydrocarbons.

Abstract:

Background Oil spills can cause severe damage within a marine ecosystem. Following a spill, the soluble fraction of polycyclic aromatic hydrocarbons is rapidly released into the water column. These remain dissolved in seawater over an extended period of time, even should the insoluble fraction be removed. The vertical distribution of the aromatic hydrocarbon component and how these become transferred is poorly understood in brackish waters. This study examines the vertical distribution of polycyclic aromatic hydrocarbons having been released from a controlled film of spilled oil onto the surface of brackish water. Methods The study was undertaken under controlled conditions so as to minimize the variability of environmental factors such as temperature and hydrodynamics. The distribution of polycyclic aromatic hydrocarbons was measured in the dissolved and suspended phases throughout the 1 m water column with different intensity of water sampling: 1, 2, 4, 7, 72, 120, 336, 504 and 984 h. Results The total concentration of polycyclic aromatic hydrocarbons ranged from 19.01 to 214.85 ng L–1 in the dissolved phase and from 5.14 to 63.92 ng L–1 in the suspended phase. These hydrocarbons were released immediately following a controlled spill attaining 214.9 ng L–1 in the dissolved phase and 54.4 ng L–1 in the suspended phase near the cylinder bottom after 1–2 h. The 2–3 ring polycyclic aromatic hydrocarbons dominated in the dissolved phase (60–80%), whereas the greater amount of 4–6 ring polycyclic aromatic hydrocarbons (55–90%) occurred in the suspended phase. A relatively low negative correlation (rS = –0.41) was determined between the concentration of phenanthrene and suspended matter, whereas a high negative correlation (r = − 0.79) was found between the concentration of pyrene and suspended matter. Despite the differences in the relationships between the concentration ratio and amount of suspended matter the obtained regressions allow roughly to predict the concentration of polycyclic aromatic hydrocarbons.

Abstract:

Having a source attributed to anthropogenic activities such as incomplete combustion or pyrolysis of organic materials, polycyclic aromatic hydrocarbons are toxic organic pollutants that the ubiquity is no more to be proved. The purpose of this work is to identify and quantify the hydrocarbons pollution of the Mboppi River. Eight (8) samples of water were collected in the river during the dry and the rainy season (4samples for each season). Hydrocarbon fraction was extracted by magnetic agitation of the mixture water/hexane followed by clean-up, fractionation and subsequently, analysis using gas chromatography coupled to a Flame Ionization Detector (GC-FID). Total concentrations of polycyclic aromatic hydrocarbons in the samples were ranged between 196.3-1040.19 µg/L in the river. Polycyclic aromatic hydrocarbons with more than four rings showed the highest concentrations in the river independently from the seasonal variation while the polycyclic aromatic hydrocarbons with 2 or 3 rings were usually present in low concentrations or sometimes undetectable. From the data, it was also possible to conclude that there is predominance of petroleum sources, and essentially closed to the more industrialized areas. Mboppi River can then be considered as being among the most polycyclic aromatic hydrocarbons polluted environment in comparison with some rivers and estuaries.

Abstract:

formed during incomplete combustions of organic substances but few to be mention such as cigarettes, coal etc. They are usually found as a mixture containing two or more compounds such as soot. The emissions of PAHs in Nigeria have contributed significantly to the environment and live of aquatic organisms. Thus, this paper reviewed the contamination of polycyclic aromatic hydrocarbon (PAHs) in the water, sediments and organisms in inland and coastal waters. Methodology: Literatures of relevant and previous studies of polycyclic aromatic hydrocarbons in the water, sediment and organism within and outside Nigeria were reviewed. Results: The contamination of polycyclic aromatic hydrocarbons (PAHs) was known to be carcinogenic, mutagenic, teratogenic and can cause adverse effect on human health, wildlife and aquatic lives with no report on mammals in the aquatic environments. Conclusion and Recommendation: Polycyclic aromatic hydrocarbons (PAHs) reviewed displayed different effects caused in the lives of human and aquatic organism based on the concentration level. Their sources were more of anthropogenic than natural source with varied concentrations at various source points due to different activities in question. The positive impact of polycyclic aromatic hydrocarbon on fish and other aquatic organisms as a result of bioconcentration, biotransformation and biomagnification become a threat to humans that rely on eighty percent of aquatic resources. Therefore, conceived efforts should be made to reduce these effects, general public monitoring of polycyclic aromatic hydrocarbon on discharge sources in the biosphere.

Abstract:

Human exposures to polycyclic aromatic hydrocarbons (PAHs) occur as components of complex mixtures. Evaluations of health risks posed by complex mixtures containing PAHs rely on the toxicological knowledge of prioritized PAH mixture components, assuming that these PAHs share a common mode of action and that the sum of the contributions of these PAHs equals the toxic potency of the mixture (i.e., additivity). Traditional toxicity testing methods emphasizing apical endpoints have had limited success at evaluating the validity of these assumptions. Toxicogenomic tools that are able to rapidly generate toxicologically-relevant and mechanistic information have gained acceptance in the regulatory arena for individual chemicals; however, the applicability of these tools for chemical mixtures has been inadequately addressed. This thesis used toxicogenomic tools to (1) improve the understanding of mechanisms underlying the adverse, toxicological responses induced by individual PAHs and (2) evaluate the contention that transcriptional profiles and pathway information can be used to critically examine interactions between individual PAHs in PAH-containing mixtures, and the assumption of additivity. Microarrays were used to profile gene expression changes (transcriptomes) in forestomach, liver, and lung tissues (targets of PAH exposure) from mice orally exposed to three doses of eight individual PAHs, two defined PAH mixtures, and one complex PAH-containing mixture (coal tar). The results revealed that each PAH induced transcriptional changes that were significantly associated with several pathways implicated in carcinogenesis. However, despite a uniform ability to induce DNA damage (i.e., DNA adducts), mutations, and increases in enzyme activity, the pathways differ across PAHs and tissues. A novel strategy that employs single-PAH transcriptome data to models of additivity revealed that the assumption of additivity in PAH mixtures is valid at the pathway level; however, the independent action model of additivity yielded better estimates compared to concentration addition (used in human health risk assessment of PAH mixtures) or generalized concentration addition. Additionally, predicted and observed coal tar-induced transcriptional benchmark doses were comparable to those derived from previously published coal tar-induced murine lung tumour incidence data. Overall, this thesis demonstrates the utility of toxicogenomic data to expand the current understanding regarding the toxic potential of individual PAHs and PAH-containing complex mixtures.

Abstract:

The gas-phase ion chemistry of hydroxyl- and amino-substituted polycyclic aromatic hydrocarbons (PAHs) and their protonated counterparts were studied using mass spectrometry. Ions were generated using an electron ionization (EI) source and the unimolecular chemistry of metastable ions was studied by performing mass-analysed ion kinetic energy spectrometry (MIKES) experiments with a magnetic sector tandem mass spectrometer. Collision-induced dissociation (CID) experiments were used in conjunction with MIKES experiments to determine ion structure. The ten molecules studied were: 1-naphthol, 2-naphthol, 1-naphthylamine, 2-naphthylamine, 1-aminoanthracene, 2-aminoanthracene, 1-phenanthrol, 9-phenanthrol, 1-hydroxypyrene and 1-aminopyrene. Since it is believed that larger PAHs, on the order of more than 50 carbon atoms, populate the interstellar medium, the goal of this study was to attempt to extrapolate the results from smaller systems to larger ones. The trends found include: hydroxy-substituted PAH radical cations lose carbon monoxide spontaneously and amino-substituted PAH radical cations lose HCN. Mechanisms for both processes are proposed, and it appears from the present results that this process should extrapolate to larger PAHs. Another trend found was that all the remaining fragment ions were always a closed ring. Protonated amino-substituted PAHs were generated by electrospray ionization using a quadruple time-of-flight mass spectrometer. By protonating 1-naphthol and 2-naphthol using methane in the high-pressure EI source, it was found that they lost exclusively H2O. As for 2-naphthylamine, 1-aminoanthracene and 2-aminoanthracene, it was found that 2-naphthylamine lost NH3 and a hydrogen atom, NH3being the dominant channel. However, as the ion size 3 increases, the hydrogen-loss channel became the dominant channel. This means that larger PAHs will likely lose exclusively a hydrogen atom to reform the parent radical cation.

Abstract:

This study consists of a non-traditional molecular and stable isotope approach to analyze organic matter (soluble bitumen and produced oil/condensate) from the Montney Formation low-permeability reservoirs, with the purpose of identifying source(s) of hydrocarbons, accumulation history and post accumulation processes. The same approach bases on the distribution of compound classes such as aromatic carotenoids, polycyclic aromatic hydrocarbons (PAHs), bicyclic alkanes, and oxygen-polar compounds. The geochemical screening has been enhanced with performing compound specific isotope analysis (CSIA) of n-alkanes and selected aromatic hydrocarbons. Widely spread PAHs, the presence of molecular indicators of euxinia, and hydrocarbon mixtures identified using CSIA profiles, are some of the key findings from this research, which will improve our understanding of the Montney petroleum system(s).
