Two specific alkylated PAHs (Figure 1), 2-methylnaphthalene
and 1-methylphenanthrene, were found at [greater than or equal to] MDL.
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.
Henry Waxman, D-CA, said that the substance was likely 2-methylnaphthalene
and that the company destroyed tainted packaging before announcing the recall.

Mass transfer and bioremediation of naphthalene, 2-methylnaphthalene
and 1,5-dimethylnaphthalene have been studied in a rotating bioreactor modified with the addition of baffles and beads.
The airborne concentrations of compounds commonly present in creosote (indene, naphthalene, 2-methylnaphthalene
, 1-methylnaphthalene, biphenyl, acenaphthene, dibenzofuran, and fluorine) were determined for all air samples tested.
Additionally, we have sulfidogenic consortia that re-mineralize benzene, naphthalene, 2-methylnaphthalene
, and phenanthrene as a sole carbon source.

He was able to show naphthalene, 2-methylnaphthalene
, and phenanthrene were degraded under sulfidogenic conditions but not under the other reducing conditions.
Not previously considered for TEFs were the naphthalene derivatives 1-methylnaphthalene and 2-methylnaphthalene
, which were prominent PAHs in the coal tar mixtures (Culp et al.
