National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Coal Tar Pitch Sampling Analysis.

PB82151309

Publication Date	1972
Personal Author	Coulter, P. D.; Petro, B. A.
Page Count	150
Abstract	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 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.
