Analytical Methods Evaluation and Validation for 1,2,4- Trichlorobenzene; 1,2,4,5-Tetrachlorobenzene; Pentachlorobenzene; and Polychlorinated Terphenyls.
NIOSH 1981 May:92 pages
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-2. 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.
