IVo extrn. nethods for detn. of DOT residues in green tea were compared by Goodwin (Analyst 86, 697, 1961), who used acetone and Mills (JAOAC 46, 186, 1963), who used acetonitrile. After purlf. by passage through Nuchar Attaclay and Florisll, reap., the exts. were analyzed by GC on a 5 ft x 1/8 In col. of 2% of QF-1 on Chromosorb G, 60-80 mesh, at 170*0, with ^2 50 ml/min, as carrier gas. The best extrn. was obtained by using a Soxhlet app., with acetone. 100 ml for a 20 g sample, or acetone-hexane, 1:1, as solvent. 91-89-83a-61b )0696 No. 73-0696 AND POLYCHLORINATED BIPHENYL (ARDCL0R 1242) EFFECTS OF UPTAKE ON E. C0LI GROWTH J. Kail and S. Sandifer (Sect. Preventive Med., Medical Univ., SC); L. Prleater (Environmental Health Lab., State Board Health, Columbia, SC); C. Graber (Microbiol. Dept., Med. Univ. SC) Water Res. No. 7: 837-41 (July 1972) DDT at 0.01 and PCB at 0.01 and 0.1 ppm consistently stimulated E. coll growth in vitro. Differences between treatments and controls were statistically significant at the 952 confidence level. E. coll uniformly converted DDT to DDD, 75% and DDE, 25%. DDT and PCB were analyzed by GC using a 6 ft x 1/4 in, o.d., col. packed with 3% SE-30 on 60-80 mesh ABS Chromosorb W and 2% QF-1 on 60-80 mash ABS Chromosorb W.

Oil Chemists' Soc. 50, No. 1: 11-15 (Jan. 1973) Fatty acid compns. of partially deuterated prods, were detd. with a Varian Aerograph GC equipped with dual 6 ft x 1/8 in s.s. cols, packed with 15% EGSS-X on Gaa Chrom P, operated with FID and a nitrogen carrier gas flow rate of 20 ml/ min. Col. temp, was 190C. Positional isomers of various monoene, conjugated diene and trlene fractions were detd. by reductive ozonolysis followed by temp, progr. GC of aldehydes and aldehyde esters (50*-190*C at the rate of 6*C/mln).
