“…Polycyclic aromatic hydrocarbons (PAHs) are well-known as persistent environmental contaminants and have carcinogenic, mutagenic, and/or endocrine-disrupting properties. − PAHs are unintentionally generated by incomplete combustion of organic substances, − then spread to air, soil, water, and sediments, and are found in cereals, vegetables, fruits, meat, and fish . A cohort study in China has estimated that Incremental Lifetime Cancer Risk (ILCR) related to exposure to PAHs via food consumption was 6.65 × 10 –5 (4.41 × 10 –5 to 1.02 × 10 –4 as interquartile range) .…”

Smoke-dried bonito is a traditional Japanese processed fish product containing considerable amounts of polycyclic aromatic hydrocarbons (PAHs). Their concentrations generally exceed the maximum levels under EU regulations. Although halogenated PAHs (XPAHs) have attracted attention owing to their high toxicities, no information on the occurrence of XPAHs in smoke-dried bonito is available. In this study, we investigated the occurrence of PAHs and XPAHs in smoke-dried bonito purchased in the Japanese market in 2020 and evaluated the contamination levels in terms of concentrations and incremental lifetime cancer risks (ILCRs). The total concentrations of PAHs were 419–1070 μg kg–1 and those of XPAHs were 0.306–1.01 μg kg–1. Because smoke-dried bonito is consumed in low amounts, the ILCR of PAH4 via dietary consumption of smoke-dried bonito was the lowest among those of other smoked foods. Smoking by hot-plate heating of wood chips should be one of the effective countermeasures to reduce PAH contamination.

“…Of the PAHs in the surface soils, the total concentration was 1,190 ng/g on average in all samples, and the mean levels at each site were as follows: urban (1,940 ng/g) > suburban (1,410 ng/g) > local (1,330 ng/g) > park (779 ng/g) (Figure 3(a)). These contamination levels were relatively high compared with levels previously reported for Asian soils [30]. Compared to the composition of aromatic rings among the sampling sites, PAHs with relatively high molecular weights (6-rings) were dominant in samples from the urban site, followed by the suburban, park, and local sites, whereas the rates of PAHs with relatively low molecular weights (≤3-rings) increased in the inverse order (Figure 4(a)).…”

In this study, we investigated the potential of swallow feces as a bioindicator to evaluate soil pollution from anthropogenic sources. This biomonitoring was performed with trace elements, polycyclic aromatic hydrocarbons (PAHs), and their chlorinated derivatives (ClPAHs) as pollutants. The concentration of total trace elements targeted was reasonably consistent in both soil and fecal samples. The composition of individual trace elements also showed a similar profile across the sampling sites. The concentration of total PAHs varied in both soil and fecal samples among the sites, whereas their composition showed a similar profile. There were no significant correlations between total PAH or total ClPAH concentrations in either soil or fecal samples. This suggests that the sources and metabolic pathways in swallows may differ between PAHs and ClPAHs. Predictions of individual contaminant levels in soil samples were made from corresponding datasets of the feces using partial least squares analysis, and showed significant correlations based on the magnitude order. It permitted to roughly complement the levels of contaminants in the soils by the estimated equation.

“…Organochlorine pesticides (OCPs) and polycyclic aromatic hydrocarbons (PAHs) are two typical groups of persistent organic pollutants (POPs). They have been widely studied due to their unique properties [1][2][3][4], such as persistence, long-range transport, toxicity and bioaccumulation. OCPs and PAHs present considerable mobility, and their occurrences have been widely reported on many regional occasions and even on the global scale over the past decades [2,[5][6][7][8][9].…”

To investigate the concentrations, spatial distribution, potential sources and mass fluxes of organochlorine pesticides (OCPs) and polycyclic aromatic hydrocarbons (PAHs) in waters from the Danshui River Basin, a total of 20 water samples were collected and analyzed from a karstic river in Western Hubei of Central China. The average concentrations of total OCPs and PAHs in the river water were 4719 pg·L−1 and 26.2 ng·L−1, respectively. The characteristic ratios of different isomers and the composition analysis of individual OCPs and PAHs revealed that HCHs originated from a mixed input of technical HCHs and Lindane, DDTs were mainly from technical DDTs, and PAHs mainly originated from biomass and coal combustion. The mass flux analysis showed that PAHs had a higher emission and heavier burden than OCPs in the Danshui River Basin. OCPs and PAHs emitted from agricultural or other human activities could enter the groundwater and then be transported to the surface/river water in the karst area. The adsorption of OCPs and PAHs by particles and the sedimentation of particles could be the primary processes to intercept these pollutants in the water of the karstic river system.
