“…To assist in validating the accuracy of PAH measurements, several Standard Reference Materials (SRM's) have been issued by the National Bureau of Standards since 1980 for use in the determination of these compounds (5)(6)(7)(8)(9)(10)(11)(12). These SRM's range in analytical difficulty from a simple calibration solution of the 16 priority pollutant PAH (SRM 1647) (5) to several complex, natural matrix materials such as shale oil (SRM 1580) (6,10), crude oil (SRM 1582) (7,11), air particulate material (SRM 1649) (8,12,13), and diesel particulate matter (SRM 1650) (9). A new SRM, which is intermediate in complexity when compared to existing SRM's, has been prepared and certified for use in the determination of PAH.…”

“…To avoid the time-consuming and tedious fraction collection and off-line measurements, some investigators have examined on-line measurement of highmolecular-weight PAHs. Romanowski et al [12] determined PAHs with molecular weights up to 456 u in a coal tar extract by using GC-MS with a modified high temperature interface. Fetzer et al [13] used conventional HF'LC with photodiode array detection to identify 13 high-molecular-weight PAHs in diesel exhaust particulates; identification was based on comparison of W/k spectra and retention times with those of authentic standards synthesized in their laboratory.…”

Polycyclic aromatic hydrocarbons (PAHs) comprise a class of potentially hazardous com- pounds of concern to the U.S. EPA. The application of particle-beam (PB) liquid chromatography-mass spectrometry (LC-MS) to the measurement of high-molecular-weight PAHs was investigated. Instrument performance was evaluated for 16 PAHs in the molecular weight range 300-450 u. The PAHs were separated by reverse-phase high-performance liquid chromatography via a polymeric octadecylsilica (C-18) packing and gradient elution with methanol-tetrahydrofuran. On-column instrument detection limits, as measured by selected ion monitoring on the singly charged molecular ion of each PAH, were found to be 0.15-0.60 ng for PAHs with molecular weights up to 352 u and 2-4 ng for PAHs with molecular weights greater than 352 u. Instrument response was generally linear for PAHs with molecular weights 300-352 u and generally nonlinear for PAHs with molecular weights greater than 352 u. The PB electron impact mass spectra of the PAHs were found to vary with the ion distribution ratio of the singly charged molecular ion to the doubly charged molecular ion, dependent on molecular weight, ion source temperature, and concentration. Analysis by PB LC-MS was applied to extracts of PAH-spiked soil and a PAH-contaminated soil from the Pacific Northwest. Target analyte concentrations in the PAH-contaminated soil ranged from 0.85 to 84 µg/g. Quantitative estimates for nontarget PAHs also were determined. Analysis of a second soil extract from a hazardous waste site in the northeast part of the United States displayed isomeric patterns of high-molecular-weight PAHs similar to those of the Pacific Northwest extract.

“…HMW PAHs have been identified in combustion-related samples such as coal tar, [13][14][15] fuel combustion exhaust, [16][17][18] and in the environmental air particulate matter. [19][20][21] The U.S. Department of Health and Human Services (HHS) has listed four MW302 isomers including dibenzo[a,l]pyrene (DBalP), DBaeP, DBaiP, and dibenzo[a,h]pyrene (DBahP) as potential carcinogens to humans.…”

in an industrial complex site (site A) and an electronic waste recycling site (site B) to determine the seasonal and diurnal variations of 19 individual polycyclic aromatic hydrocarbons (PAHs) with molecular weight 302 (MW302) including four highly carcinogenic dibenzopyrene (DBP) isomers dibenzo [a,l] [a,e]fluoranthene (DBaeF), constituting 52.0 to 55.4% of the total MW302 isomers. All the MW302 isomers showed notable seasonal variations. Most of the MW302 isomers in site B showed distinctive diurnal variations with higher concentrations occurring in the night. Taking into account both concentration and potency equivalence factors (PEFs), the strongest carcinogen in the analyzed samples was DBaiP, and the ratios of sum carcinogenic potency of four highly carcinogenic DBP isomers to benzo[a]pyrene (BaP) was about 0.94 in winter to 1.89 in summer, indicating the importance of DBP isomers for the risk assessment. Health risk assessment indicated that on average, 1 in 100 000 residents in the two industrial sites may have an increased risk of cancer due to PAH exposure.
