This study was performed to find out whether in acute exposure to trimethylbenzene (TMB) isomers the dose effect relationship is linear or biphasic. In experiments performed on rats, the effect of four solvents was studied: three TMB isomers: 1,3,5-TMB (mesitylene)
E Janik-Spiechowicz et al.
Mutation research, 412(3), 299-305 (1998-05-26)
The three trimethyl isomers of benzene (hemimellitene, 1,2,3-TMB; pseudocumene, 1,2,4-TMB and mesitylene, 1,3,5-TMB) were investigated for different genotoxicity endpoints: in vitro, in the Ames test with Salmonella typhimurium TA97a, TA98, TA100 and TA102 strains in the presence and absence of
J Järnberg et al.
Toxicology and applied pharmacology, 140(2), 281-288 (1996-10-01)
The objective of this study was to determine the uptake and disposition of inhaled trimethylbenzenes (TMBs) in man. The toxicokinetics were studied in 10 male, healthy volunteers exposed to TMB vapor in an exposure chamber for 2 hr during a
Z Korsak et al.
International journal of occupational medicine and environmental health, 13(3), 223-232 (2000-12-08)
Toxic effects of exposure to 1,2,3-trimethylbenzene (hemimellitene) in the condition of subchronic inhalation experiment were examined. Rats were exposed to vapours of hemimellitene at concentrations of 123 mg/m3, 492 mg/m3 and 1230 mg/m3, 6 h/day, 5 days/week for 3 months.
T Tomas et al.
International journal of occupational medicine and environmental health, 12(1), 73-84 (1999-06-09)
In a series of acute experiments on rats the potential of toluene, mesitylene, hemimellitene and pseudocumene to affect the CNS function was assessed following an analysis of spontaneous and evoked hippocampal and cortical activity. The electrophysiological examinations were performed on
