Toxic fluorinated compounds as by-products of certain boron trifluoride-catalyzed industrial processes. Bedford, C. T.; Blair, D.; Stevenson, D. E. (Shell Toxicol. Lab., Shell Res. Ltd., Sittingbourne, Engl.). Nature (London), 267(5609), 335 (English) 1977. CODEN: NATUAS. DOCUMENT TYPE: Journal CA Section: 4 (Toxicology) Section cross-reference(s): 23, 35 Toxic CH2FCH2OH [371-62-0] and/or 2-(2-fluoroethoxy)ethanol [373-22-8] were detected in low concns. in a range of industrial chemicals manufd. from ethylene oxide [75-21-8] using BF3 catalyst. F-, a by-product of BF3-catalyzed reactions, may be the source of the toxicants.

Method for testing the degree of avoidance reaction in rats to acute raticides

Method for testing the degree of avoidance reaction in rats to acute raticides. K'osev, M. (MA, Sofia, Bulg.). Epidemiol., Mikrobiol. Infekts. Boles., 21(2), 48-52 (Bulgarian) 1984. CODEN: EMIBA3. ISSN: 0425-1482. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) Gray rats (Rattus norvegicus) of the exptl. group were allowed to observe for 2 h the action of acute raticides on another group over wire fencing, then the fencing was removed and the exptl. group was given the bait with the same poison. The obsn. decreased the bait intake and thereby increased the survival after exposure to 3% zinc phosphide [51810-70-9], 0.5% Crimitox (castrix) [535-89-7], 0.5% Flutritex-2 (ethylenefluorohydrine) [371-62-0], and 1% Flutritex-1 (fluoracetamide) [640-19-7] from 0.21, 0.22, 0.03, and 0.03, resp., to 0.78, 0.30, 0.44, and 0.03, resp., thus showing different degrees of avoidance reaction.
