Fluoranthene quantities

GC-MS examination of the PAH fraction of sample S2 (S2-C2) gave very similar results the total ion chromatogram is shown in Figure 5. Major constituents were phenanthrene, fluoranthene, pyrene, and methyl, dimethyl/ethylphenanthrene/anthracene. Relative abundance of some C2-alkylphenanthrenes/anthracenes were higher in this sample than in S1-C2. Smaller quantities of benzo[ghi]fluoranthene, chrysene, benzo[ajanthracene, tripheny-lene, benzo[b,j, k]fluoranthenes, and benzo[e aJpyrenes and were characterized by MS. In addition, most compounds listed in Table 1 were also detected in this sample. 

The authors reported an example of such solvent effects in the catalytic two-step denitrogenation of coal liquid distillates. With large quantities of added 1-methylnaphthalene or 20% added pyrene or fluoranthene, no additional catalyst is necessary for the second step to achieve high levels of denitrogenation. 

Saxena et al. [512] used polyurethane foams to concentrate trace quantities of six representatives of polynuclear aromatic hydrocarbons (fluoranthene, benzo(k)fluoranthene, benzo(j)fluoranthene, benzo(a) pyrene, benzo(ghi) perylene, and indeno(l,2,3-cd)pyrene) prior to regular screening of these compounds in US raw and potable waters. Final purification and resolution of samples was by gas chromatography and two-dimensional thin layer chromatography, followed by fluorometric analysis and quantification.

Not only the quantity but also the quality of organic matter has been shown to influence bioavailability (Karickhoff et al., 1979). Sediment organic carbon provides a primary food source for benthic organisms. DeWitt et al. (1992) found that sediment pore water partitioning and toxicity of fluoranthene to the amphipod, Rheopyxinius abronius, were affected by sediment organic matter quality. 

PROBABLE FATE photolysis insufficient data, but photolysis may be very important, atmospheric and aqueous photolytic half-lives 21 hrs-2.6 days, in the unadsorbed state, it will degrade by photolysis with a half-life of a few days to a week oxidation chlorine and/or ozone in sufficient quantities may oxidize fluoranthene, photooxidation half-life in air 2.02-20.2 hrs hydrolysis not an important process volatilization not an important transport process sorption adsorption onto suspended solids and sediments is probably the dominant transport process, when released to water, it will quickly adsorb to sediment and particulate matter in the water...
