Abbreviations used: LACs - sum of 2,3-ring aromatic contaminants (lower molecular weight).

HACs - sum of 4-6-ring aromatic contaminants (higher molecular weight).

nd - indicates that the analyte was not detected above the limit of detection which ranged from 2 to 30 ng/g (ppb) wet weight.

RSD - relative standard deviation is the standard deviation divided by the mean and expressed as a percent,

Results were determined by gas chromatography (GC)/mass spectrophotometry (MS) - multiple ion detection.

Napththalene-d8 was the internal standard (surrogate standard) for naphthalene through c4-naphthalenes. Acenaphthene-d10 was the internal standard for acenapththylene through C1-fluoranthenes/pyrene. Benzo[a]pyrene-d12 was the internal standard for benz[a]anthracene through benzo[ghi]perylene.

Percent recoveries for the internal standards averaged 86%, RSD = 19%, n = 35. Percent recoveries of the surrogates include quality assurance samples.
