“…Polycyclic aromatic hydrocarbons (PAHs) are organic pollutants released into the environment through incomplete combustion of organic materials, with the emission from anthropogenic events predominant [ 1 ]. Chemically, PAHs are compounds containing only carbon and hydrogen atoms, arranged in two or more fused aromatic rings by sharing a pair of carbon atoms between the rings.…”

Exposure to polycyclic aromatic hydrocarbons (PAHs) through diet is gaining concern due to the risk it poses to human health. This study evaluated the bioaccessibility of PAHs contained in charcoal-grilled beef and chicken in different segments of the gastrointestinal tract (GIT) with regard to the degree of doneness and fat content of the meats. The levels of 15 PAHs in the grilled meat samples and bioaccessible fractions were determined using high-performance liquid chromatography (HPLC) equipped with PAH column, and UV and fluorescence detectors. Total PAHs were found in beef (30.73 ng/g) and chicken (70.93 ng/g) before its digestion, and different PAHs’ bioaccessibility were observed in the different segments of GIT, with the highest in the stomach followed by the small intestine, despite the relatively higher bioaccessibility of individual PAHs in grilled beef as compared to those in grilled chicken. Additionally, the PAHs’ bioaccessibility increased with the increase in the degree of doneness. Positive linear correlation was observed for the PAHs’ bioaccessibility and the fat contents of grilled meat. Overall, this study highlights the influence of meat doneness (cooking time) and fat contents on the bioaccessibility and bioaccumulation of PAHs.

“…United States Environmental Protection Agency (USEPA) and European Union (EU) have identified sixteen PAHs (Table S1 ) as priority pollutants due to their toxicity and risks to human health and the environment 4 – 7 . For example, PAHs in sediments can pose detrimental effects on benthic organisms and pelagic organisms 8 , 9 . Therefore, PAHs concentrations in sediments have been widely investigated in the past decades for assessing their risks 10 – 18 .…”

In this study, we observed that four congeners, including naphthalene (Nap), acenaphthylene (Acy), phenanthrene (Phe), and benz(a)anthracene (BaA), are the characteristic congeners for predicting the emission and the sediment concentrations of polycyclic aromatic hydrocarbons (PAHs). A novel multiple relationship of the total PAHs concentrations (C∑PAHs) in sediments with the concentrations of four congeners was established (p < 0.01, R2 = 0.95) using published data over the past 30 years. Moreover, the multiple linear relationship of the total PAHs emission factors with the emission factors of four congeners was also established (p < 0.01, R2 = 0.99). Interestingly, the ratio of multicomponents coefficient from the multiple linear relationship in sediments to that from the multiple linear relationship in emission sources correlated positively with octanol–water partition coefficient (logKow) (p < 0.01, R2 = 0.88) of the four PAHs congeners. Therefore, a novel model was established to predict CΣPAHs in sediments using the emissions and logKow of the four characteristic PAHs congeners. The percent sample deviation between calculated C∑PAHs and their observed values was 54%, suggesting the established model can accurately predict CΣPAHs in sediments.

The presence of PAHs in sediments is a concern because of these compounds are toxic to pose detrimental effects on benthic organisms and pelagic organisms (i.e., via resuspension) 8,9 . Therefore, the survey of PAHs in sediments have been conducted worldwide in the past decades for assessing their risks [10][11][12][13][14][15][16][17][18] .…”

In this study, four congeners, i.e., naphthalene (Nap), acenaphthylene (Acy), phenanthrene (Phe) and benz(a)anthracene (BaA), screened out by hierarchical clustering analysis from 16 PAHs, are the characteristic PAHs congeners in emission sources and in sediments. Novel multiple linear relationships, i.e., the total PAHs emission factors and the total PAHs concentration with the emission factors of Nap, Acy, Phe and BaA and their sediment concentrations data reported in the past 30 years were established, respectively. The same characteristic congeners observed for PAHs in sediments and in emission sources indicates that the concentration of PAHs in sediments are largely dependant on the PAHs emission. Moreover, the ratio of multicomponents coefficient from the multiple linear relationship in sediments to that in emission sources correlated positively with the logKow values and biodegradation half-lifes of four characteristic congeners, indicating PAHs concentrations in sediments are also alternated by their environmental behaviors including sorption and biodegradation. However, the established relationship gives a useful way to predicted C∑PAHs in sediments without the PAHs emissions data and can eliminate the effects of environmental behaviors and the difference of emissions in various regions.
