Abstract

Concentrations of six polycyclic aromatic hydrocarbons (benzanthrone, benz[a]anthracene, chrysene, fluoranthene, pyrene, and triphenylene) of soil samples from Diboll, an East Texas city (USA), were analyzed with gas chromatography-mass spectrometry (GC-MS). Samples were collected from five sites; Old Orchard Park, two heavy traffic intersections (Judd Street and Lumberjack Drive), an industrial site (West Borden Drive), and a truck stop. Acetone and dichloromethane extracts in all samples showed the presence of fluoranthene and pyrene. The sum of fluoranthene and pyrene concentrations in sites followed the order West Borden Drive > Judd Street > Lumberjack Drive > Old Orchard Park > truck stop. Concentrations of fluoranthene and pyrene were in the range 12.3 – 396.5 μg kg-1 (ppb) and 13.6 – 209.8 μg kg-1 (in dry soil), respectively. Benzanthrone, benz[a]anthracene, chrysene, and triphenylene concentrations were < 2 ppb levels. The higher concentrations in soils were associated with sites close to heavy traffic and vehicular emissions.

Comment: Numerous studies on occurrence of PAHs in soil have been conducted in the past five decades. Hence, the study lacks novelty. Probably, the authors may want to treat these experiments as preliminary investigation for a more novel study.

Comment: This study addresses specif aims in a specific location in a rural area. Studies on the apportionment of PAHs in this area are non-existent. A busy high highway (Highway-69) with traffic flow passes through the the city. Thus, the thrust of the study are (i) a study of the contribution and apportionment of the PAHs studied (4 ring PAHs) - whether they come from diesel or gasoline combustion engines. The other objective of the study, a part from the quantitation of concentrations, is for interrogation of the contributions of nearby industrial sites to the the total PAH concentrations found in the study.
