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.

Analytical Methods Evaluation and Validation for 1,2,4-Trichlorobenzene; 1,2,4,5-Tetrachlorobenzene; Pentachlorobenzene; and Polychlorinated Terphenyls.

PB92128297

Publication Date	1981
Personal Author	Dillon, H. K.; Bryant, M. L.
Page Count	102
Abstract	The development of a personal sampling and analytical method for the determination of three chlorinated benzenes in the air, including 1,2,4-trichlorobenzene (120821), 1,2,4,5-tetrachlorobenzene (95943), and pentachlorobenzene (608935), are described. The selection of collection device and preliminary evaluation, an independent sampling method for the determination of the chlorinated benzenes, and evaluation of the total method are discussed. The personal air sampler consisted of a teflon filter in a stainless steel holder and a solid sorbent tube containing Amberlite XAD-s. The pooled relative standard deviations for the determinations of the compounds by the overall sampling and analytical method were 9.3 percent for 1,2,4-trichlorobenzene, 9.7 percent for 1,2,4,5-tetrachlorobenzene, and 9.8 percent for pentachlorobenzene.
