Determination of polycyclic aromatic hydrocarbons in a coal tar standard reference material

Polycyclic aromatic hydrocarbons (PAHs) in continental shelf sediment of China: Implications for anthropogenic influences on coastal marine environment

“…Perylene was detected in nearly all samples except for site 22, with concentration ranges of 2e980 ng/g (average: 65 ng/g), accounting for 3.5e96.6% (average: 26.5%) of S 22 PAH (List S2 (Jenkins et al, 1996), wood combustion (wood) (Yunker et al, 2002), lignite and brown coal combustion (Lign) (Oros and Simoneit, 2000), bituminous coal combustion (Bitu) (Oros and Simoneit, 2000), coal tar combustion (coal tar) (Wise et al, 1988), crude oil combustion (Crud) (Benner et al, 1990), tobacco combustion (Toba) (Zhang et al, 2009), gasoline exhaust (Gaso) (Rogge et al, 1993), and diesel exhaust (Dies) (Yunker et al, 2002). The categories A (sites 1e3), B (sites 4e8), C (9e13), D (sites 14e17, 31), E (sites 18e23), and F (sites 24e30) were grouped on a basis of geographical locations (Table S1).…”

Polycyclic aromatic hydrocarbons (PAHs) in the water column and sediment core of Deep Bay, South China

“…Ratios of phenanthrene to anthracene (Ph/An) and fluoranthene to pyrene (Fl/Py) have been widely used to distinguish petrogenic and pyrogenic sources of PAHs (Gschwend and Hites, 1981;Sicre et al, 1987;Yang, 2000;Yunker et al, 2002;Chen et al, 2006). PAHs of petrogenic origin are generally characterized by Ph/An values >10, whereas combustion processes often result in low Ph/An ratios (<10) (Wise et al, 1988;Benner et al, 1990). For the Fl/Py ratios, values greater than 1 have been used to indicate pyrolytic origins, and values less than 1 are attributed to petrogenic source (Sicre et al, 1987).…”

Degradation of Benzo[ a ]pyrene by Mycobacterium vanbaalenii PYR-1

“…There are more than 100 different PAH compounds, and the health effects of individual PAHs are not exactly alike (27,28). The presence of PAHs in contaminated soils and sediments poses a significant risk to the environment, since they have ecotoxic, mutagenic, and, in some cases, carcinogenic effects.…”
