Title Distribution of conduction velocity in the ulnar nerve among lead exposed workers
Original title Rozkład prędkości przewodzenia we włóknach nerwu lokciowego u osób zawodowo narażonych na działanie ołowiu [in Polish]

Abstract Clinical and neurophysiological assessments of the peripheral nervous system were carried out in 34 lead-exposed workers and 20 healthy controls. None of the workers showed clinical signs of neuropathy or abnormalities in routine neurographic examination. Compared with controls, a significantly lowered conduction in slow-conducting motor fibres and neurogenic changes in EMG were observed in workers with a blood lead concentration over 400 µg/1 and in workers with free erythrocyte protoporphyrin levels over 70 µg/100 ml. It is concluded that the neurotoxic effect of lead on peripheral nerves is manifested by the damage of slow-conducting motor nerve fibres when overt neuropathy is not yet visible.
