Slotnick has also opined (personal communication) that intranasal zinc may well have more long-lasting effects in some species, including that so vain as to call itself "Homo sapiens." It may be next to impossible to determine if an individual's anosmia resulted from the application of intranasal zinc (it could have resulted from a viral infection of the olfactory mucosa, which stimulated the patient to use intranasal zinc). That said, the available evidence does strongly suggest that zinc solutions, should they reach the olfactory mucosa, can do long-lasting damage. My summary of the research I have been able to find is at http://personal.ecu.edu/wuenschk/Zinc.htm . Having experienced how devastating anosmia can be, I would NEVER deliberately introduce a zinc solution into my nose!

Slotnick et al (2000) showed that Alberts and Galef (1971) were mistaken, and the application of zinc sulphate to the nasal mucosa of the rat does not produce anosmia.
