T Tomas et al.
International journal of occupational medicine and environmental health, 12(4), 331-343 (2000-03-07)
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)
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, 10(3), 303-311 (1997-01-01)
Sensory respiratory irritation effects of trimethylbenzene isomers (TMBs) (hemimellitene, mesitylene and pseudocumene) in male Balb/C mice were investigated in conditions of acute exposure and in male Wistar rats in conditions of repeated 90-day inhalation exposure to pseudocumene. The pseudocumene, mesitylene
