Polycyclic aromatic hydrocarbon emissions from the combustion of crude oil on water

Polycyclic aromatic hydrocarbon fingerprints in the Pichavaram mangrove–estuarine sediments, southeastern India

“…Phenanthrene (PHE) is thermodynamically a more stable isomer than anthracene (ANT). Hence, petroleum contains relatively more PHE than ANT, and it is characterized by the high PHE/ANT ratio (Benner et al, 1990). The plots between ANT/(ANT+PHE) vs. FLT(FLT+PYR) and BaA/(BaA+CHR) vs. FLT(FLT+PYR) in these sediments suggest that PAHs derived from a mixture of both petrogenic and pyrolytic sources (Fig.…”

Polycyclic aromatic hydrocarbons contamination in subsoil from outskirts of Beijing, People's Republic of China

“…In the studied area, the unsubstituted PAHs were the most abundant components, which suggested combustion or pyrolysis process was dominant for the PAHs (Benner et al, 1990). Moreover, at low to moderate temperature, as in the wood stove (Lake et al, 1979), or as from the combustion of coal (Laflamme and Hites, 1978), low molecular weight parent PAH compounds are abundant.…”

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).…”
