The compounds mainly fall into the following 12 aromatic hydrocarbon series: naphthalene (m/z 128, m/z 142, m/z 156, m/z 170, m/z 184, m/z 198), phenanthrene (m/z 178, m/z 192, m/z 206, m/z 220), benzopyrene (m/z 252), fluoranthene
(m/z 202, m/z 216), dibenzothiophene (m/z 184, m/z 198, m/z 212, m/z 226), benzonaphthothiophene (m/z 234), dibenzofuran (m/z 168, m/z 182, m/z 196), fluorene (m/z 166, m/z 180, m/z 194), chrysene (m/z 228, m/z 242, m/z 256), biphenyl (m/z 154, m/z 168, m/z 182), triaromatic sterane (m/z 231) and benzohopane (m/z 191).
(99%) and MAH (99%) and PP-g-MAH (weight grafting degree: 0.
, and pyrene are also commonly found at levels exceeding 5 percent of total PAH concentrations at these sites (Ozretich et al.
Naphthalene, biphenyl, acenaphthene, fluorene, fluoranthene
, and pyrene showed partial compatibility.
9:30 Phototoxicity of Sediment-Associated Fluoranthene
5 cm is especially remarkable with a 3-fold and 2-fold improvement for fluoranthene
and acenaphthylene, respectively.
The combustion products fluoranthene
and pyrene each appeared in three drinking-water samples, as did triclosan, an antibacterial agent in household products (SN: 5/27/00, p.
The objective of the study was to determine what surfactant level is needed to effectively make sand-bound fluoranthene
bioavailability to S.
Human exposure to compounds that are metabolized to dihydrodiols, particularly fluoranthene
and benzo[c]phenanthrene, is extensive.
LOCs for anthracene, phenanthrene, fluoranthene
, fluorene, naphthalene, and pyrene--PAHs that are not considered carcinogens--were calculated using a safety threshold known as a reference dose (RfD) (FDA 2010).
5%) contains several PAHs: phenanthrene, fluoranthene
, pyrene, benz[a]anthracene, chrysene, benzo[b+k]fluoranthene
, benzo[a]pyrene, etc.
Tests of soil at the junction of two stormwater outfall pipes encompassing drainage to surface water downstream of an unlined construction and demolition landfill and a lined municipal solid waste landfill in the Rogers-Eubanks community revealed the presence of arsenic, chromium, lead, nickel, benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene
, benzoic acid, chrysene, fluoranthene
, indeno(1,2,3,-cd)pyrene, and pyrene (data not shown).
