Numerous investigations have been carried out on the acute and chronic toxicity of volatile aromatics (for reviews, see [3, 10, 12, 13, 132, 137, 195-199, 224-228]). Four newest reviews should especially be mentioned  

Chronic toxication, metabolic changes, changes in the blood composition, changes in the white blood count, leukocytosis, anaemia, chromosomal changes at least 0.01-1 g/m and more 3-20 Many observations without statement of concentration  

Odour perception thresholds Electrical activity of the cerebral cortex biochemical changes in pregnant mammals 2.8-5 mg/m 1-2 mg/m 0.1-2 mg/m 0.6 mg/m 0.6-0.7 mg/m 0.2 mg/m Zero effect level for changes of the ALA-metabolism 0.004 mg/m
