Coal Tar Pitch Sampling Analysis.
NIOSH 1972 Jul:143 pages
The abilities and efficiencies of sampling procedures and analytical methods are evaluated so that potential hazards associated with coking and roofing operations may be determined. Methods are presented for the determination of: benzene soluble material, polynuclear aromatic compounds, benzo(a)pyrene (50328) in airborne particulates, the composite emission index of volatile matter collected on air sampling filters and on glass fiber filters, trace metals in airborne particulates, and organic vapors. Methods are given for polynuclear aromatics using gas chromatography and ultraviolet spectrophotometry, and liquid chromatography and spectrophotometry, after different extraction techniques. Modifications, improvements, and drawbacks to the methods are noted. (Contract No. 099-71-0007)
