This contract is for the supply - for acquisition, delivery and installation of a gas chromatography linked to a mass spectrometer including a PTV and a thermal desorption unit for the analysis of PAHs (naphthalene, acenathylene , acenaphthene
, fluorene, phenanthrene, anthracene, fluoranthene, pyrene, benzo (a) anthracene, chrysene, benzo (b) fluoranthene, benzo (j) fluoranthene, benzo (k) fluoranthene, benzo (a) pyrene, indeno (1,2,3 -cd) pyrene, dibenzo (a, h) anthracene and benzo (g, h, i) perylene).
2001 Phenol AIFBR This study (a) Olive mill wastewater (b) Coal conversion wastewater (c) Pentachlorophenol (d) Poly aromatic hydrocarbons (PAHs) such as naphthalene, acenaphthene

The concentrations of acenaphthene
, acenaphthylene, anthracene, fluorene and naphthalene were near or beyond the detection limit.
EPA 2012) to estimate ambient air concentrations of 16 PAHs (including the 12 PAHs measured in this study, as well as acenaphthene
, acenaphthylene, fluorine, and naphthalene) attributable to emissions from major stationary sources (e.
Levels of phenanthrene, pyrene and acenaphthene
are relatively low.
All EPA Priority Pollutant PAHs except acenaphthene
, acenaphthylene, and anthracene, were detected in all of the blends; however, only benzo[a]antracene, benzo[a]pyrene, and bezo[f]luoranthene consistently exceeded remediation criteria.
We tested for naphthalene, 2-methylnaphthalene, 1-methylnaphthalene, anenaphthylene, acenaphthene
, flourene, anthracene, phenanthrene, fluoranthene, pyrene, chysene, benz(a)nthracence, benzo(a)pyrene, benzo(b)flouranthene, benzo(k)fluoranthene, indeno(l,2,3-cd)pyrene, dibenz(a,h)anthracene, benzo(ghi)perylene.

Levels of all 16 priority pollutant PAHs including naphthalene, acenaphthylene, acenaphthene
, fluorene, phenanthrene, anthracene, fluoranthene, pyrene, benzoanthracene, chrysene, benzo[b]fluoranthene, benzo[f]fluoranthene, benzo[a]pyrene, indenopyrene, benzo[e] perylene, and dibenzo[a,h]anthracene were quantified by comparison with known standards (EPA 1982).
Among aromatic compounds lower benzene alkylsubstituted derivatives, naphthalene, methyl- and dimethylnaphthalenes, diphenyl, acenaphthene
, fluorene, phenanthrene, and anthracene were identified.
Naphthalene, biphenyl, acenaphthene
, fluorene, fluoranthene, and pyrene showed partial compatibility.
