“…3), which also indicates that vehicle emissions were also a PAH source in the urban area. In addition, at a depth of 10-30 cm, a high proportion of fluorene was detected, which is characteristic of coal and/or its combustion products (Lee et al 1982;Radke et al 2000). In our previous study on the heterocyclic aromatic hydrocarbons in Beijing soil, we found that coal and its combustion products were primary sources in the urban soil (Zhang et al 2007).…”

Vertical distribution of both the concentration and composition of polycyclic aromatic hydrocarbons (PAHs) in ten profiles in Beijing has been investigated. The results showed that PAH concentrations and compositions in topsoil from different sampling sites were different. PAH concentrations were much higher in topsoil of the investigated urban area, industrial region, and paddy field with wastewater irrigation than in other areas. Moreover, PAH concentrations in topsoil were much higher than those at greater depth, where the concentrations were relatively consistent in most soil profiles. The fingerprints of PAHs in the samples from topsoil (0-30 cm) in the same profiles were similar and were obviously different from those at greater depth, suggesting that PAH sources were consistent in topsoil samples and were discriminating between topsoil and deeper soils. PAHs in topsoil mainly arose from mixed sources of combustion of liquid fuel, coal, and/or wood, as well as wastewater irrigation, while those at greater depth were derived from soil genesis and the process of soil formation.

“…The ratios of FL/Pyr, IND/IND + BghiP, BaP/BghiP and BaP/BaP + CHR can be used to identify the predominant sources for PAHs since the values are quite different to various sources such as gasoline emission, diesel emission, and coal combustion, respectively (Sawicki, 1962;Lee et al, 1982;Khalili et al, 1995;Kavouras et al, 1999;Kavouras et al, 2001;Manoli et al, 2004;Chen et al, 2005;Mantis et al, 2005). In this study, the ratio FL/Pyr, IND/IND + BghiP, BaP/BghiP and BaP/BaP + CHR of the six sampling sites range from 0.94 (DL) to 1.27 (SZ), 0.48 (BC) to 0.54 (HX), 1.10 (HX) to 1.25 (BC) and 0.39 (DL) to 0.43 (DXC and BC) in heating period respectively (Table 5).…”

Spatial variations were predominantly due to the different strengths of source emission. The total PAHs concentrations at Dongli Monitoring Station (DL) site and Beichen Science and Technology Park (BC) site were higher than those at other four sites in heating period, while those at Meijiang community (MJ) site and Beichen Science and Technology Park (BC) site were higher in no-heating period. Higher PAHs concentrations during heating period and lower concentrations during no-heating period were observed at the six sampling sites, which may be caused by the stronger emissions from stationary combustion sources in heating period and the quicker air dispersion, washout effects, photodegradation and higher percentage in the air in vapor phase in no-heating period. The PAHs concentrations in gaseous phase were predicted with gas/particle partition model, and the BaP and BaP equivalency results indicated that the health risk of gas and particle phase PAHs to human in Tianjin were higher than that in other cities. The contributions from potential sources to PAHs in PM 10 were estimated by the diagnostic ratios between PAHs and principal component analysis (PCA). In whole sampling period, coal combustion was found to the predominant contributor of PM 10 -bound PAHs, followed by vehicles emission and wood combustion.

“…The EPA Method 3510C was adopted in the extraction of organic fractions from the water samples (Lee et al, 1982) and was employed. 100 mL of water sample was measured into a 250 mL separatory funnel, and then extracted three times with 20 mL of methylene chloride, giving ~60mL of final extracting solvent.…”

Poly-brominated Di-phenyl Ethers (PBDEs) are important chemical flame retardants, added to many consumer products to reduce the spread of fire. This study was aimed at assessing the bio-accumulation of polybrominated diphenyl ethers (PBDEs), oxidative stress, and histopathological alterations in Malapterurus electricus from Epe Lagoon, Lagos, Nigeria. Water samples were collected from three different stations of the lagoon and the physiochemical parameters were analyzed using Horiba. Also, fish specimens of Malapterurus electricus were randomly selected from vendors at the Epe Lagoon, Lagos Nigeria. These specimens were then dissected to remove intestine, liver and parasite for examination. The excised liver, intestine and parasite (Electrotaenia malopteruri) were then taken to the laboratory to analyze for bioaccumulation of PBDEs, oxidative stress, and histopathological assessment. Results showed that the physico-chemical parameters of water body had their mean values either below or within established permissible limits. BDE-183 had the highest concentration accumulated in the liver meanwhile BDE-209 congener was not detected at all across the intestine, liver and parasite. The oxidative stress response parameters, GPx (glutathione peroxidase) was highest for both intestine and liver, GPx, and SOD (superoxide dismutase) were higher in the uninfected fish than the infected one. Histopathological findings in the uninfected fish showed normal villi structure, normal mucosa, submucosa, and muscularis while the infected fish showed a mild increase in the connective tissue of the sub-mucosa and a focal area of loss of villous structure. The results reflect the biological effects of PBDEs pollution on the aquatic organisms and in combination with oxidative stress markers and histopathology of the guts; the endangered state of the Epe lagoon was unveiled.retardant properties, as detailed by Madgett et al. (2022). These substances are integral components in the fabrication of various commercial and consumer goods, including but not limited to textiles, paint, building materials, automobiles, polyurethane foams used in furniture, mattresses, carpets, car seats, plastics, and electrical appliances. They are extensively employed as non-reactive additives in textiles, polyurethane foams, thermoplastics, and electronic products, as elucidated by La Guardia et al. (2012). The composition of PBDE congener groups, such as TriBDEs, HexaBDEs, HeptaBDE, and NonaBDE, varies in their respective proportions, as discussed by La Guardia et al. (2012) and Winid (2015).PBDEs have emerged as a significant environmental pollutant due to their recalcitrant nature and capacity for bioaccumulation, resulting in adverse toxic effects. Elevated concentrations of PBDEs have been detected in air, water, sediment, and soil within densely populated regions, particularly in proximity to manufacturing, recycling, and waste disposal facilities, which constitute point sources of PBDEs in non-living media, as demonstrated by Osuala et al. (2020). PBD...
