This is a case report on acute intoxication caused by exposure to m-dinitrobenzene (DNB) that occurred in 1969 in our country. Six workers involved in the intoxication used hammers to remove the DNB crystal layer from the sur-face of an accidentally overflowed tank and were probably exposed to a large amount of DNB dust. The workers developed cyanosis which was followed by a slight to moderate anemia, viz 1.9-15.5% loss in specific gravity of the whole blood (GB). The magnitude of the anemia was not so different from those reported previously4), but prolonged recovery from the anemia was a characteristics of the intoxication cases of the present report. All the workers exposed to the chemical had been followed for ten years and it was confirmed that there was no long term adverse effect being attributable to the exposure.
