Morphological changes in the adrenergic ground plexus of the iris elicited by lead, cadmium and mercury
The environmental burden of heavy metals is steadily increasing. Among the most widely used are lead, cadmium and mercury, all known to accumulate in living organisms and produce damage to various tissues (see Olwin, 1977). During the last decade, an increasing number of papers have been published concerning the toxicity of lead, cadmium and mercury on the nervous system.
