Residual neurobehavioral impairment in a water technician exposed to hydrazine-containing mixtures.

Residual neurobehavioral impairment in concentration, comprehension, memory, task performance and mood status persisted in a water technician with respiratory and dermal exposures to hydrazine-containing mixtures prior to treatment with steroids for concurrent thrombocytopenia. The findings call attention to the possibility that residual neurobehavioral impairment may be an effect of exposure to hydrazine mixtures.
