Efforts in the area of analytical services to NIOSH for special measurement problems are summarized. Samples were difficult to analyze and outside the scope of typical analytical problems handled by NIOSH laboratories (SIC-3797). Twenty-three benzene (71432) soluble extracts for filters containing coal-tar pitch volatiles were submitted. Each extract was quantitatively analyzed for acridine (260946), benzol(a)pyrene (50328), and beta-naphthylamine (91598). Eight lacquer thinner samples were analyzed qualitatively for isopropyl-alcohol (67630), isopropyl-acetate (108214), methylethylketone (78933), methylisobutylketone (108101), isobutyl- alcohol (78831), isobutylacetate (110190), propylacetate (109604), butylacetate (123864), toluene (108883), xylenes/M, O, P-isomers (1330207), benzene, and 3-methylhexone. Three pentachorophenol samples were analyzed for 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) using gas-chromatography via electron capture. A detergent sample was analyzed for monoethanolaminedodecyl-benzene-sulfonate , o- benzyl-p-chlorophenol, tetrasodium-ethylenediaminetetra-acetate , isopropanol, benzene, toluene, and water. The analytical procedures for each element are listed.
