The standard curve of PAHs was including naphthalene, acenaphthylene, acenaphthene, fluorene, phenanthrene, anthracene, fluoranthene, pyrene
, benzo(a)anthracene, chrysene, benzo(b) fluoranthene, benzo(a)pyrene, indeno(1,2,3-cd) pyrene
, and benzo(g,h,i)perylene as shown in figure 1.
The ratios of excretion to intake via dermal absorption for fluorene, phenanthrene, and pyrene
were lower than the ratios from dietary exposure but higher than the ratios from inhalation.
Polycyclic aromatic hydrocarbons (PAHs): Naphthalene, acenaphthylene, acenaphthene, phenanthrene, fluorene, anthracene, pyrene
, chrysene (internal standard (i.s)), benzo(a)anthracene, fluoranthene, benzo(b)fluoranthene, benzo(k)fluoranthene, benzo(a)pyrene, benzo(g,h,i)perylene, indeno(1,2,3-cd)pyrene and dibenzo(a,h)anthracene.
However, 12.08 and14.68 ppb for Benzo(e)pyrene and 5.62 ppb for Indenol (1, 2, 3 - cd) pyrene
exceeded the expected limit.
Earlier we reported about testing CDA fibers and films as matrices for the SSF of pyrene
taken as a model PAH [21, 22].
These PAHs are naphthalene, fluorene, phenanthrene, and pyrene
, all present in high concentrations in the complex Superfund-derived PAH mixture.
All 16 PAH standards, naphthalene (NAP), acenaphthylene (ACNY), acenaphthene (ACN), fluorene (FL), phenanthrene (PHEN), anthracene (ANTH), fluoranthene (FLU), pyrene
(PYR), benz[a]anthracene (B[a]A), chrysene (CHRY), benzo[b]fluoranthene (B[b]F), benzo[k]fluoranthene (B[k]F), benzo[a]pyrene (B[a]P), indeno[1,2,3-cd]pyrene (I-123-cd_P), dibenz[a,h]anthracene (D[ah]A), and benzo[g,h,i] perylene (B[ghi]P), were purchased from Cambridge isotope laboratories (Frontage Road, Andover, MA, USA).
, composed of four aromatic rings, originates primarily from the thermal decomposition of organic matter and its subsequent recombination (Cerniglia 1993; Samanta, Sing, & Jain, 2002; Haritash & Kaushik 2009).
Ethyl bromide (Sigma-Aldrich) and pyrene
(Molecular Probes) were used as received.
A certified solution of 16 standard polycyclic aromatic hydrocarbons (naphthalene; acenaphthylene; acenaphthene; fluorene; phenanthrene; anthracene; fluoranthene; pyrene
; benz[a]anthracene; chrysene; benzo[k] fluoranthene; benzo[b]fluoranthene; benzo[a]pyrene; indeno[1, 2,3-cd]pyrene; dibenz[a,h]anthracene; and benzo[g,h,i]perylene) with 10 mg/L concentration of each compound was purchased from Supelco, Milan, Italy.
Numerous PAHs, including benz[a]anthracene, benzo[a] pyrene
, benzo[b] fluoranthene, benzo [j] fluoranthene, benzo[k] fluoranthene, chrysene, dibenz [a,h] anthracene, and indeno [1,2,3-c,d] pyrene
, were responsible for tumors in laboratory animals when they breathed these substances in the air (David, 1990).
The fourteen contributions that make up the main body of the text are devoted to polymer hydrogel dressing in wood management, dendritic organic semiconductors based on pyrene
and triazine derivatives, preparation of polymer and ferrite nanocomposites for EMI applications, and a wide variety of other related subjects.
