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.

Development of Sampling and Analytical Methods for Carcinogens. Progress Report, January 1--September 30, 1976.

LA7058PR

Publication Date	1977
Personal Author	Morales, R.; Rappaport, S. M.; Weeks, R. W.; Campbell, E. E.; Ettinger, H. J.
Page Count	29
Abstract	Components used for the generation of aerosols and vapors of certain aromatic amines on the Occupational Safety and Health Administration list of carcinogens are described. A two-stage sampling tube incorporating a glass fiber filter followed by silica gel was developed for collecting aerosols of benzidine and 3,3'-dichlorobenzidine. For alpha - and beta -naphthylamine, a similar sampler having a greater capacity for retaining vapors was developed. Efficient desorption and sensitive analytical procedures for the quantitative determination of these four amines are described. Results of respirator canisters evaluated for protection against 4,4'-methylenebis(2-chloroaniline) and the naphthylamines are given. (ERA citation 03:026997)
