“…Results between the workers and their corresponding mannequins agree with each other and with their partner tank samples. After extraction using a modified IP-346 method (21) and reanalysis using a gas chromatograph with a time of flight mass spectrometer, detectability of the PAHs was improved for the tank and laboratory generated fume samples, since ample fume was available. Table VII contains these data, where detection limits were improved to 0.08 mg/kg except for acenaphthylene, which was 0.8 due to overlap with alkylated analogues.…”

“…Methodology followed that of SW 846-8270 C (20) protocol. With ample sample available for the tank and laboratory generated fumes, a modified DMSO (21) cleanup procedure based on IP-346 (22) was utilized to achieve lower detection limits for the unsubstituted PAHs using gas chromatography coupled with a time of flight mass spectrometer (TOF/MS).…”

This study had two fundamental goals. The first was to collect sufficient quantities of bitumen fumes used in both the roofing and paving industry in the United States to do detailed chemical and biological testing in preparation for a two-year animal skin painting study on select samples. These bitumen fumes need to be similar to the fumes to which workers in these industries are actually exposed. In this first phase, bitumen from four geographical regions of the United States were selected, which produced bitumen from four different major crude sources in roofing and four sources in paving. Each source was supplied to projects where workers were monitored for exposure. The industrial hygiene samples from workers were then tested for physical and chemical properties. These results were used to guide collection of fumes from each source using the vapor headspace of tanks containing each bitumen. Bitumen fumes were collected using the same protocol that the Fraunhofer Institute of Technology and Medicine employed in a recent animal inhalation study. The second goal of this study was to better understand previous studies conducted by NIOSH which generated fumes for mouse skin painting studies using a roofing bitumen in a laboratory fume generator. In the current study, bitumen fumes from the four roofing sources were generated using the NIOSH protocol and compared to fumes collected in the roofing work sites and taken from the tank headspace. One of the sources was selected to generate enough fumes for a chronic two-year animal skin painting study. Results from an array of physical, chemical and biological tests were used to characterize the subsequent fumes. Acceptance criteria were designed to match parameters that could be analyzed both on the workplace samples and the bitumen fumes collected from the tank and involved three basic categories: simulated distillation, fluorescence and gas chromatography/mass spectroscopy for polynuclear aromatic hydrocarbon analysis and extracted ion fingerprinting. Methods employed for the collection of these fumes were selected to optimize the capture of the most toxicologically relevant components.Distinctions between paving and roofing fume samples are outlined. Bitumen fumes from the paving sources produced from four different crude sources were quite similar to each other in a number of the tests performed. Bitumen fumes from the roofing sources also were very similar to each other. On the other hand, fumes generated using the NIOSH protocol show results that significantly differ from the corresponding worker exposures.

“…These high molecular weight components of residual petroleum products, because of their high molecular weights and general insolubility, have a very limited mobility in the However, some residual petroleum products also contain significant amounts of lower molecular weight hydrocarbons and related hetero-compounds. Particularly prominent in residual fuels and asphalts are relatively high concentrations (compared to lighter fuels) of three-through six-ring polycyclic aromatic hydrocarbons (PAHs) [25] [26] [27]. The composition and total concentration of the PAH fraction in a residual fuel oil depends on the nature and amount in it of the low viscosity blending stocks and the proportions of virgin (from crude distillation) and cracked (residues from thermal and catalytic cracking units) residues.…”
