Although poisonings (fatal and non-fatal) due to intentional or accidental acute exposure to toluene or toluene mixture fumes have been previously reported in the literature, several issues concerning lethal doses or lasting post-exposure neuropathological impairments still remain unclear. Two male painters (18 and 30 years old) were accidentally exposed to toxic concentrations of paint diluent fumes containing toluene (TL), acetone (ACT) and methyl ethyl ketone (MEK) (60:15:15 w/w/w respectively) during their work in an underground reservoir. Both workers were found unresponsive by colleagues and were immediately transferred to the regional hospital. On admission, the younger man was pronounced dead, while the other remained in the intensive care unit for 3 days and then 4 days in the internal medicine ward. TL, ACT and MEK concentrations in blood samples taken from the survivor on admission were 6.3, 30.6 and 40.5 μg/mL. Postmortem toxicology of the dead worker revealed TL, ACT and MEK blood levels of 12.4, 90.8 and 80.4 μg/mL respectively. The solvent levels in the liver, kidney, lung, brain, testis and gland were also quantified and showed a somewhat similar distribution of the chemicals among these tissues with the highest levels found in the brain and the liver. The fatal and the non-fatal outcome that resulted despite similar intoxication conditions, most probably demonstrates the interindividual tolerance among the painters who also had similar body weights. The surviving painter did not develop any neuropsychological impairment in post-exposure time. The reported case strongly emphasizes the necessity to take precautions when using paint diluents in enclosed spaces.
