- There was no neurobehavioral white spirit-induced neurotoxicity. As expected, age-related differences in motor activity were detected, however, no dose-related macroscopic or histopathological changes were found. The concentration of neurotransmitters noradrenaline (NA), dopamine (DA), and 5-hydroxytryptamine (5-HT) in various brain regions and in whole brain was changed in the 400 and 800 ppm groups.
The authors conclude that this study revealed different irreversible changes within the CNS. However, the significance of changes in neurotransmitter levels is difficult to evaluate. In the absence of any pathological or functional changes, it is difficult to determine if this is toxicological, phenomenological, compensatory, or merely a random variation - Dose descriptor:

- 600 mg/m³
- Study duration:
- subacute
- Species:

- Quality of whole database:
- Neurobehavioural effects were evaluated in rats.
In male rats exposed to white spirit type 1 (0, 600, 2400 or 4800 mg/m³ (approximately 0, 100, 400 and 800 ppm, respectively), 8 hours/day for three consecutive days), the spontaneous motor activity was decreased at the highest exposure level and the psychomotor speed was affected exposuredependently at the two highest levels. This study confirmed that acute white spirit exposure at 200 to 800 ppm could produce transient behavioral effects. Overall, the NOAEC was 600 mg/m3 (approximately 100 ppm).
Effect on neurotoxicity: via dermal route
Endpoint conclusion
- Endpoint conclusion:
- no study available
Additional information
The results of available animal studies on mineral spirits containing up to 22 volume % aromatics demonstrate that the acute CNS effects produced by concentrations as high as 800 ppm are completely reversible. The potential for persistent effects is less clear. Several studies have reported changes in behavior, neurochemistry, and sensory evoked potentials that the authors have interpreted as evidence of long-lasting, perhaps irreversible changes. However, these findings have generally been subtle and not obviously associated with functional deficits or behavioral changes. Therefore, it is not clear whether these finding are a reflection of a true neurotoxic effect or simply a measured change from baseline values without toxicological significance. There is no consistent evidence that chronic low-level solvent exposure in animal models produces irreversible CNS effects.
Justification for classification or non-classification
